Landing Expectancy
After many successful landings the go-around proficiency decays
and you anticipate every approach results in a landing. There is a
tremendous change in expectation and outcome when a landing changes to a
go-around. There is a safety boundary between the two that becomes more
and more narrow with experience. The successful pilot soon loses sight of
the go-around as a safety manoeuvre.
When do you go-around?
Anytime, for whatever reason, if you feel uncomfortable about any aspect
of the landing procedure. On approach if you feel too high, low, fast, or
slow. In the flare if not straight, ballooning, high, bouncing, slow or
fast. the go-around is an exercise of judgment. The student should never
try to save a landing. Go-around. Do not use the radio. Over a real or
imaginary runway continue straight until reaching the departure end of the
runway and a safe/noise abatement altitude before turning.
The pilot who is not
prepared for the go-around may be unintentionally preparing for an
accident. Being hesitant in making the go-around is just as likely to
precipitate an accident, as is a poor landing. The go-around is the 'Hail
Mary' of landing procedures. It is as aggressive a manoeuvre as the
non-aerobic pilot is going to make. Get in full power and accept a loss of
altitude if needed to regain flying and climb speed. Simulated go-arounds
can never create the experience of the visual and unnerving ground rising
to meet you.
Go-Around and Why
When do you go-around?
Anytime, for whatever reason, if you feel uncomfortable about any aspect
of the landing procedure. On approach if you feel too high, low, fast, or
slow. In the flare if not straight, ballooning, high, bouncing, slow or
fast. The go-around is an exercise of judgment. The student should never
try to save a landing. Go-around. Do not use the radio. Over a real or
imaginary runway continue straight until reaching the departure end of the
runway and a safe/noise abatement altitude before turning.
The earlier you go-around
the better. This is an action deemed necessary to correct control,
approach, flare, or rollout problems. Altitude allows some trade off for
airspeed. The lower the go-around the more difficult it may seem but this
is not necessarily so. You have less distance to fall in a stall the
closer to the ground you are. This is because flight within ground effect
requires less power for a given performance. The aircraft can fly close to
the ground even with full flaps. In ground effect the partial removal of
flaps is less likely to cause a stall. There is more excess power in
ground effect so that more acceleration can occur as the flaps are
removed.
The go-around should be a
smooth transition from a landing situation into takeoff configuration.
Stop landing, start climbing. The go-around usually is initiated for
instructional purposes, traffic, lack of aircraft control, weather or
surface conditions. The go- around is essentially a takeoff with full
flaps. You must have practiced at altitude so that you know ahead of time,
which pressures to anticipate as flaps are retracted, and you maintain
level flight. Flap retraction must be carefully controlled because most
training aircraft have little excess power.
The successful go-around
is predicated on the pilot's understanding of required planning, setting
aircraft attitude, cleaning up the configuration, and use of power. The
greatest enemy of planning is any form of delay, procrastination or
hesitation. The delayed go-around greatly increases the pucker factor. The
proximity to the ground should not do this but it does. Actually, the
ground proximity should rightly be considered an asset. Ground effect,
properly used, greatly enhances the ability of the aircraft to avoid the
ground, accelerate and climb. Most often go-around accidents are the
result of premature and unintentional climbs at low airspeeds. Airspeed is
money in the bank. Get the airspeed up with full SMOOTH power, a level
attitude or slight dive held against the power and flap effort to raise
the nose, and get off the flaps slowly until reaching climb speed. The
best go-around is a precision control manoeuvre when done properly. Every
move is done in anticipation of what you know will come next. If you don't
know, learn. A pilot's reliability factor can well be measured by the
smoothness with which a go-around is performed.
Knowing how to evaluate
whether you're prepared to make any specific approach is one of the more
difficult flight operations. Failure to go-around soon enough is a factor
of attitude. A delay in initiating a go-around is most apt to result in an
incident/accident.
Accidents that are
subsequent to initiation of a go-around are reflective of late decision,
poor attitude control, airspeed and heading problems and a flight path
leading to an obstacle. Making a go-around from a touchdown past the
mid-point of the runway may be too late. You are more likely to survive a
slower contact with an obstacle on the ground than a higher speed
uncontrolled contact from the air. Ground looping will use the aircraft
structure to take the initial shock of impact.
The Flight Safety
Foundation has found that pilots fail to recognize an unsalvageable
approach in time to initiate a safe go-around. The go-around, if not
always a part of your expectations, requires an instant change of
procedure. If the procedure is not known as a first learned process then
the mental and physical coordination must be performed at a more conscious
level. Although the go-around is most usually begun relatively low to the
ground, this need not be the case. If things are not right on the downwind
you can begin there and just fly the pattern at altitude. Regardless of
the aircraft the fundamentals of the go-around are the same; power,
airspeed, re-configure, climb. The go-around is not an item for
discussion. At the first idea of a go-around, it is time.
The go-around requires a
sudden switch in mental awareness. Instead of going down we must begin a
reversal of process and thinking. The areas of importance change, first
things now become last things. Full power, accelerate in level flight to
climb speed, clean up flaps, climb attitude, and trim.
Go-Around Procedure
The generic go around has the
following sequence:
1. Smoothly to full power (including carburettor heat #2)
2. Pitch initially to level for acceleration as...
3. Flaps removed by increments or milking according to speed and rate of
acceleration.
4. Pitch and trim for climb reaching Vx or Vy as required.
A safe go-around can be
accomplished at any altitude if the initial effort is just to stay at
altitude while power and configuration is adjusted to allow a climb. A
common fault is attempting to climb before the aircraft is capable of
climbing. Have a go-around plan and fly the plan.
"Go-around". Apply full
throttle smoothly but rapidly then carb heat. Anticipate the yoke and
rudder applications that will be required by your airspeed and
configuration. The "go-around" is one of the best safety procedures in
flying. If you are not positioned for a safe landing, go-around. Full
power in the go-around increases the airflow over the wing. With flaps
extended the power application causes the nose to pitch up abruptly. This
must be anticipated!! Hold forward pressure on the yoke to prevent
pitching up.
Fly the airplane is # 1.
The go-around is not an emergency, it is a standard procedure even if the FAA says it is considered an emergency procedure. The go-around is a
precautionary option. Properly performed it is neither difficult or of any
particular hazard. You don't need to tell the tower anything until they
ask your intentions. A go-around should be made any time there is a
significant deviation from intentions to land or a requirement for radical
manoeuvring. A go-around is a 'sound' controlled manoeuvre. Listen for the
sound of full power, acceleration, Vy, and climb.
Keep your eyes outside
during the go-around. Keep the aircraft coordinated and in a pre-selected
direction. Apply full power smoothly, remove carburettor heat, anticipate
torque, P-factor, and slipstream with right rudder. Keep the aircraft
level with a locked elbow and remove the flaps judiciously with reference
to your airspeed and altitude. There is no hurry. Accelerate to 65 Kts
(C-150), trim for climb and set the pitch attitude that will maintain a Vy
climb. Now, you can look at your instruments.
There are several common
faults typical to the go-around. Most problems occur when power is first
added and before flaps are raised. The student's eyes should be focused
outside the airplane on the nose attitude of the aircraft. Learn to locate
the flap switch by feel. No trim is required. The aircraft must be kept
level. The student must lock the elbow on the door. The application of
full power with flaps will tend to cause a rapid nose pitch up. P-factor
will cause the nose to turn to the left so right rudder pressure must be
anticipated. The nose must be held down or there will be a loss of
airspeed. This will require locking the arm on the door and a full palm
pressure forward. The pitch-up and left turning of the nose must be
anticipated and corrected before it occurs. Apply throttle BEFORE carb
heat. If you are having a problem you probably forgot to milk up the
flaps.
Fly the airplane is # 1.
The go-around is a precautionary option. Properly performed it is neither

there is a significant deviation from intentions or a requirement for
radical manoeuvring. A go-around is a sound controlled manoeuvre. Listen
for the sound of full power, acceleration, Vy, and climb.
Forgetting to bring up
flaps is the most common student fault. Aircraft are certified, when new,
to be able to climb at 2-degrees in normal, utility, and aerobatic
categories with full flaps. Just as old instructors have more trouble
making the climb into an aircraft, so do old airplanes have trouble making
the climb for which they were originally certificated.
The manner used for
removal of flaps depends on the airspeed. The old FAA recommendation was
to take 20 degrees off initially, get climb speed, and then take off the
rest. This is still good unless the aircraft is below 60 kts. Below 60 kts
the flaps should be 'milked' up by quick applications of the switch while
being sure not to go past neutral. If you don't want to chance looking at
the airspeed indicator, use the 'milking' method until the sound of the
aircraft indicates climb speed. The nose should be level until climb speed
is acquired. Any attempt to climb will result in loss of airspeed. In this
very slow configuration, the sudden and complete removal of flaps can
result in an immediate stall or sudden contact with the ground. Get the
speed; then climb.
Raising flaps too quickly
or too much can precipitate a stall. Be gentle. From 40-degree flaps, a
slight removal reduces mostly drag. This is true up to about 20-degrees of
flap. From 15-degrees to no-flaps you are losing mostly lift. Flap removal
by measured stages reduces the change in control forces, change in
attitude, and required pilot reaction. The second most common student
fault in a go-around is failing to use the pre-landing checklist on the
second approach.
Hold the nose on the horizon while bringing up the flaps with minimal
delay. Since we should be at 60 kts we can bring up 20 degrees of flaps at
once and immediately bring back the yoke to set and hold what we have
learned to visualize as a proper attitude to hold altitude as the aircraft
accelerates to 65. If we stay level this should occur quickly and we can
bring up the rest of the flaps and establish a climb attitude. Trim for
climb. It will probably be necessary for the instructor to re-establish
the pre-go-around configuration several times. It is essential that the
go-around procedure be smoothly performed in the correct sequence at the
correct speeds. Once performed well at altitude the go-around is ready for
use at ground level. Milk up at speeds below 60 knots. Flaps may be
brought up without milking once climb speed is attained. Yoke is used to
prevent any undesired sink. Trim as required.
There are several common
faults typical to the go-around. Most problems occur when power is first
added and before flaps are raised. The student's eyes should be focused
outside the airplane on the nose attitude of the aircraft. Learn to locate
the flap switch by feel. No trim is required. The aircraft must be kept
level. The full application of power with flaps will tend to cause a rapid
nose pitch up. P-factor will cause the nose to turn to the left so right
rudder pressure must be used in anticipation. The nose must be held down
or there will be a loss of airspeed. This will require locking the arm on
the door and a full palm pressure forward. The pitch-up and left turning
of the nose must be anticipated and corrected before it occurs. Apply
throttle BEFORE carb heat. If you are having a problem you probably forgot
to milk up the flaps.
For some reason many
students think that the carburettor heat must go off before throttle
application. It doesn't. The throttle should be applied smoothly first and
then the carb heat taken off with the thumb to get full power. The
position of the carb heat control was designed to be pushed in with the
right thumb. A too rapid application of throttle can cause the engine to
load up with excess fuel. This causes a delay in getting full power.
Smooth throttle operation will give smooth engine operation and allow
smoother application of rudder. It is surprising how often students seem
to think that the hand must stay frozen on the throttle to keep it in. It
doesn't. Keep the friction lock of the throttle snug. By holding the
throttle you will fail to get the flaps up. The yoke pressure makes them
think that something is wrong with the trim. There isn't. Once full power
is applied the right hand goes immediately to the flap switch.
There is a go-around
situation that can cause instinctive reactions to overcome training. This
is when the time of the go-around is delayed until an obstacle gets so
close that both power and instinctive raising the nose occurs due to
perceived danger. The result is a nose high, low speed, prelude to an
accident. In any go-around the nose must be held level during the use of
full power. The climb speed must be attained and retained during removal
of flaps. The climb will naturally result from the power, configuration,
and airspeed. For this reason some go-around instruction should include
this situation. As in many flying situations, instinctive reactions can
bite you.
The student should be made
to realize that all of the final approach procedures are, when arranged in
a given sequence, the landing process. For a landing the airspeed must be
made to transition smoothly from cruise, to approach, to stall. There will
be a sequence of turns, left or right, while descending. The trim and
flaps must be smoothly coordinated in application to maintain the approach
angle and speed. Power is smoothly changed from cruise to 1500 to off. The
power off stall at moment of ground contact is the landing.
At some airports a go-around may not be possible due to geographical
features. This one-way airport should never be attempted without good
proficiency both in flying and judging aircraft performance. It is best to
overfly at a safe altitude before making your approach. Density altitude
performance limitations is a reason to carefully consider your options
before using an airport where a go-around is a possibility.
The go-around is an exercise in good judgment. Scenarios can be because of
traffic, turbulence, hazards, speed and approach problems. The earlier the
decision the better. Procedures close to the ground are more critical in
their need for correct procedure and performance. Largest single
experience grouping of go-around accidents is pilots with 100 to 500
hours.
A go-around that is both
close to the ground and at low initial power requires anticipatory forward
yoke and rudder pressure to prevent radical pitch and heading changes.
Hold near level flight until acceleration occurs. There is always a
certain amount of ground shyness during a low-level go-around. The
go-around sequence is power, pitch, and flaps. The power goes to full with
appropriate simultaneous rudder. The pitch goes to level and flaps are
raised incrementally until reaching Vy. Fly to the right side of the
runway. Obey noise abatement procedures.
Delay close to the ground
is always dangerous because the delay means an additional loss of
altitude. Power application must be both positive and smooth so as to
allow engine to adapt to the situation. The pilot must anticipate the need
for using rudder and forward (locked) pitch to avoid pitch up and loss of
airspeed. There are occasions where descending into ground effect may be
beneficial since it increases effective engine power, propeller efficiency
and reduced drag. Aircraft will accelerate to climb speed more quickly and
allow quicker removal of flaps.
The use of ground effect is a variable depending on wing span and density
altitude. The ground effect you get in winter will not be there in summer.
Leaving ground effect too early can easily put the aircraft behind the
power curve. This means that altitude must be sacrificed in order to get
airspeed. It is far better to gain excess airspeed before you begin to
climb out of ground effect. Just as you must learn to plan ahead when
passing traffic with a low powered car, so must you learn to plan ahead
when climbing from a low speed, low altitude situation.
Flap removal should be in
stages with the size of stage much smaller the lower the airspeed and
higher the aircraft. The flight region from full flaps to half flaps is
where removal will reduce drag considerably more than it will reduce lift.
Go-Around Preparation
When you have been flying a
while, you expect to land...every time. The go-around becomes unusual,
abnormal, and unprepared for. When ATC calls a go-around you are usually
high enough and fast enough to perform without any special anticipation.
The lower and slower you get into the landing procedure the less likely
will you be prepared for the go-around. Do not add additional trim in
anticipation of making the flare attitude easier. Such additional trim
will greatly increase the control pressures and likelihood of a go-around
stall.
A crosswind landing
increases the likelihood of a go-around because of the possibility of
uncorrected drift. You don't want to land with side loads on the landing
gear or off runway. The crosswind go-around requires the pilot to make a
change in orientation. While the landing is made with a wing-low heading
parallel to the runway, the go-around requires a wings-level crab heading
at an angle to the runway.
The go-around and missed
approach is best initiated before slowing to Vref since it reduces the
acceleration time required for Vy. Go to climb power, using throttle
before carburettor heat, clean up flaps/gear, maintain positive climb rate
and runway heading. All of the factors in the prior paragraph are
important in making the go-around determination. The pre-Vref speed,
headwind component, and weight all affect the pilot's sight-line. The
determination of the sight-line is the judgmental factor used in choice of
the go around.
Go-Around and Flare
Even inside these C. G. limits
your normal reaction time to a ballooned landing flare or a bounced
landing may create sensations and flight attitudes that cause your
reaction time of one second to make the situation worse. You are pushing
or pulling on the yoke at the wrong time. The only correct procedure is to
GO-AROUND. Apply full power, hold the aircraft level, milk up the flaps,
stay level to obtain climb speed, climb out and make a new landing
approach.
If you are behind the
power curve when the go-around becomes necessary it is too late. Behind
the power curve means that your angle of attack is so great that there is
insufficient power to climb. Gaining speed requires a certain loss of
altitude. With your AGL (above ground level) near zero, ground contact is
assured. Get the power off so that a bounce will not make you airborne and
behind the power curve at ever a higher altitude.
What Makes the Go-around A Problem:
Pilot indecision that
results in too much runway behind you and not enough in front.
Pilot optimism in belief that he/she can salvage a poor approach to make
a good landing rather than go around and make a new landing approach.
If you are behind the
power curve when the go-around becomes necessary it is too late. Behind
the power curve means that your angle of attack is so great that there is
insufficient power to climb. Gaining speed requires a certain loss of
altitude.
Why Accidents Are Related to the To-around:
1. Failure to initiate at
first indication of a problem.
2. Failure to use rudder to maintain directional control.
3. Failure to anticipate effects of power.
4. Incorrect use of flight controls, especially ailerons, flaps and rudder
Go-around Carburettor Heat
Because carburettor heat is taken
off before taking off during touch-and-go's, many students think that the
carburettor heat must go off before throttle application. It doesn't. For
the go-around the throttle should be applied smoothly first and then the
carb heat taken off with the thumb to get full power. The position of the
carb heat control was selected so it could pushed in with the right thumb.
A too rapid application of throttle can cause the engine to load up with
excess fuel. This causes a delay in getting full power. Smooth throttle
operation will give smooth engine operation and allow smoother application
of rudder. It is surprising how often students seem to think that the hand
must stay frozen on the throttle to keep it in. It doesn't. Keep the
friction lock of the throttle snug. By holding the throttle you will fail
to get the flaps up. The yoke pressure makes students think that something
is wrong with the trim. There isn't. Once full power is applied the right
hand goes immediately to the flap switch.
Making the Go-around Safe
Have the go-around procedure
as part of your prelanding list. The "go-around" is one of the best safety
procedures in flying. If you are not positioned for a safe landing,
go-around. 150 annual go-around mistakes occur every year. Less than 20%
are by student pilots. Student pilots do not have the high expectations of
landing that many pilots develop in the 100 to 500 hour range. Caveat: The
more experience you get the more you should practice go-arounds.
The phase of an aircraft
in the takeoff/landing sequence most likely to cause a fatal accident is
during the go-around. The ability of a pilot to make a timely decision is
the significant issue. An unexpected tailwind presents the most difficult
decision making situation. Pilots should not allow themselves to be
victimized by either other pilots or ATC into making downwind takeoffs or
landings. Effective risk management means that the pilot should know the
limits of his piloting ability and those of his aircraft. There is a
practical side to safety that requires the go-around to be considered the
first and best option when a landing is in doubt.
The go-around requires the
student to overcome many instinctive and false ideas. We are not trying to
get away from the ground, yet. We are initially gaining airspeed and
cleaning up the aircraft for climb. We want to go faster, not up.
Established in the approach configuration of trim, flaps and power the
aircraft is descending. By making a significant increase in power the nose
wants to rise. This instinctively seems like a great idea but the cost in
airspeed can be excessive to fatal. We must hold the nose level. Lock the
elbow against the door panel to prevent the yoke and nose from erratic
movement.
The student must be warned
to anticipate with rudder and yoke the effect caused by a smooth but rapid
power application. Every change in flap setting and airspeed will require
a different amount of anticipation. Failure to anticipate will cause the
aircraft to balloon, lose airspeed and make the go-around more difficult
to perform. Watch the nose, keep it level. Listen for an increase in
airspeed before looking at the indicator. At 60 kts the aircraft will be
able to hold altitude while the flaps are raised. Below 60-kts the
aircraft will probably sink if flaps are raised all at once. Climb at 65.
A speed faster than 65 will not let you climb as well. (C-150)
Remember--The idea that
just adding power to an airplane will make it fly slower is another
example of a flying contradiction is not easily accepted or understood by
students. In every other situation in life, adding power makes things go
faster. This phenomenon is best demonstrated at altitude. Establish the
airplane in trimmed low cruise of 70 kts. Add full power with a touch of
rudder to hold heading. The nose will rise and the aircraft will slow. Do
this again without the use of rudder to note the effect of P-factor.
Go-Around & Low Approach
We have made a series of left and
right go-arounds at altitude and are now ready for the close to the ground
real thing. The proximity of the runway and ground creates tensions that
affect the student's ability to perform. By agreement, no landings will be
made. Much of the psychological pressure is thereby removed if the student
knows that NO landing are going to take place.
First at 200', then at
100', then at 50' and lastly in the flare. The distinction between the
go-around procedure at above 60-kts and at below 60-kts is illustrated in
the last instance. We will now proceed to do at least four identical low
approaches in the opposite pattern before flying home. The errors common
to the go-around should be allowed to occur so that they can be brought to
the attention of the student.
The instinctive desire to
add power abruptly and climb, especially on the lower go-arounds, should
be anticipated by the instructor. Smooth throttle operation will give
smooth engine operation and allow smoother application of rudder. Most
control problems occur in the interval between power application and
removal of flaps. The pitch up and left turning of the nose must be
ANTICIPATED and corrected BEFORE it occurs. Putting more than one finger
behind the yoke on a go-around is a 'probable cause' of over reaction and
abrupt control movements.
The go-around procedure
varies somewhat in every situation but there are two basic situations that
require significantly different control pressures. If the go around is
initiated at approach speed or higher the flaps can be safely brought up
immediately after full power is applied with just a momentary pause at 20
degrees to check climb speed and performance.
If the go-around is initiated at less than approach speed the flaps must
be 'milked' up while the plane is led in a level attitude and allowed to
accelerate to climb speed. At climb speed the flaps are removed. The most
common fault is for the student to freeze on the throttle and forget to
bring up the flaps. The most dangerous fault is for the student to take
off the flaps too quickly at too slow a speed. This causes the plane to
sink and perhaps contact the ground. Student control inputs will be
excessive and in reaction rather than anticipation. Raising the nose to
stop the sink lowers the speed even more. The more standardized the
procedure used in removing the flaps the better the student can anticipate
the control pressures required. The low-speed go-around must be practiced
until it can be done correctly and safely.
Heard about an instructor
who would not teach go-arounds because they were considered dangerous.
Like almost any area of flying, the improperly executed go-around can lead
to loss of control and/or a stall. If the go-around does not adequately
compensate for winds by using a crab angle for the heading the pilot may
experience directional control problems. The wing low and opposite rudder
is used on final to keep the nose straight with the runway. At the moment
of go-around the aircraft is allowed to crab into the wind as required to
keep the ground course over the runway regardless of the heading. The
stall during the go-around is most likely to occur if the aircraft is not
allowed to accelerate in level flight while slowly bringing up the flaps.
At approach speeds a rapid removal of flaps will precipitate a stall.
Go-around Flaps
The manner used for removal of
flaps depends on the airspeed. The old FAA recommendation was to take 20
degrees off initially, get climb speed, and then take off the rest. This
is still good unless the aircraft is below 60 kts. Below 60 kts the flaps
should be 'milked' up by quick applications of the switch while being sure
not to go past neutral. The nose should be level until climb speed is
acquired. Any attempt to climb will result in loss of airspeed. In this
very slow configuration, the sudden and complete removal of flaps can
result in an immediate stall or sudden contact with the ground. The stall
during the go-around is most likely to occur if the aircraft is not
allowed to accelerate in level flight while slowly bringing up the flaps.
Get the speed; then climb.
Raising flaps too quickly
or too much can precipitate a stall. Be gentle. From 40-degree flaps, a
slight removal reduces mostly drag. This is true up to about 20-degrees of
flap. From 15-degrees to no-flaps you are losing mostly lift. Flap removal
by measured stages reduces the change in control forces, change in
attitude, and required pilot reaction.
Forgetting to bring up
flaps is the most common student fault. Aircraft are certified, when new,
to be able to climb at 2-degrees in normal, utility, and aerobatic
categories with full flaps. The second most common student fault in a
go-around is failing to use the prelanding checklist on the second
approach.
Go-Around Hazards
Have the go-around procedure as
part of your prelanding list. The go-around is one of the best safety
procedures in flying. If you are not positioned for a safe landing,
go-around. 150 annual go-around mistakes occur every year. Less than 20%
are by student pilots. Student pilots do not have the high expectations of
landing that many pilots develop in the 100 to 500 hour range. The more
experience you get the more you should practice go-arounds. Most problems
occur when power is first added and before flaps are raised.
If the go-around does not adequately
compensate for winds by using a crab angle for the heading the pilot may
experience directional control problems. The wing low and opposite rudder
is used on final to keep the nose straight with the runway. At the moment
of go-around the aircraft is allowed to crab into the wind as required to
keep the ground course over the runway regardless of the heading. Most
control problems occur in the interval between power application and
removal of flaps. The pitch up and left turning of the nose must be
ANTICIPATED and corrected BEFORE it occurs. Putting more than one finger
behind the yoke on a go-around is a 'probable cause' of over reaction and
abrupt control movements.
Your normal reaction time
to a ballooned landing flare or a bounced landing may create sensations
and flight attitudes that cause problems. Your reaction time of one second
is likely to make the situation worse. You are pushing or pulling on the
yoke at the wrong time. The only correct procedure is to GO-AROUND. Apply
full power, hold the aircraft level, milk up the flaps, stay level to
obtain climb speed, climb out and make a new landing approach.
There is a go-around
situation that can cause instinctive reactions to overcome training. This
is when the time of the go-around is delayed until an obstacle gets so
close that both power and instinctive raising the nose occurs due to
perceived danger. The result is a nose high, low speed, prelude to an
accident. In any go-around the nose must be held level during the
application of full power. The climb speed must be attained and retained
during removal of flaps. The climb will naturally result from the power,
configuration, and airspeed. For this reason some go-around instruction
should include this situation. As in many flying situations, instinctive
reactions can bite you.
When you have been flying
a while, you expect to land...every time. The go-around becomes unusual,
abnormal, and unprepared for. When ATC calls a go-around you are usually
high enough and fast enough to perform without any special anticipation.
The lower and slower you get into the landing procedure the less likely
will you be prepared for the go-around. Do not add additional trim in
anticipation of making the flare attitude easier. Such additional trim
will greatly increase the control pressures and likelihood of a go-around
stall.
Special Circumstances
At some airports a go-around may
not be possible due to geographical features. This one-way airport should
never be attempted without good proficiency both in flying and judging
aircraft performance. It is best to overfly at a safe altitude before
making your approach.
There is a go-around
situation called 'getting-behind-the-power-curve' that arises when the
go-around is delayed. Behind the power curve means that your angle of
attack is so great that there is insufficient power to climb. Gaining
speed requires a certain loss of altitude. Instinctive reactions overcome
training until an obstacle gets so close that both power and instinctive
raising the nose occurs due to perceived danger. The result is a nose
high, low speed, prelude to an accident. A delayed go-around that adds
incremental power changes can create this situation where there is no more
power available and altitude must be surrendered. If the altitude is not
available a go-around is not possible. Get the power off so that a
crash/bounce will not make you airborne and behind the curve at ever a
higher altitude.
Go-Around Practice
Even inside C. G. limits your
normal reaction time to a ballooned landing flare or a bounced landing may
create sensations and flight attitudes that cause your reaction time of
one second to make the situation worse. You are pushing or pulling on the
yoke at the wrong time. The only correct procedure is to GO-AROUND. Apply
full power, hold the aircraft level, milk up the flaps, stay level to
obtain climb speed, climb out and make a new landing approach.
Hold the nose on the
horizon while bringing up the flaps with minimal delay. Since we should be
at 60-kts (C-150) we can bring up 20-degrees of flaps at once and
immediately bring back the yoke to set and hold what we have learned to
visualize as a proper attitude to hold altitude as the aircraft
accelerates to 65. If we stay level this should occur quickly and we can
bring up the rest of the flaps and establish a climb attitude. Trim for
climb. It will probably be necessary for the instructor to re-establish
the pre-go-around configuration several times. It is essential that the
go-around procedure be smoothly performed in the correct sequence at the
correct speeds. Once performed well at altitude the go-around is ready for
use at ground level. Milk up at speeds below 60 knots. Flaps may be
brought up without milking once climb speed is attained. Yoke is used to
prevent any undesired sink. Trim as required. Keep track of your trim
settings.
All Phases of the Go-Around
The go-around should be a smooth transition from a landing situation
into takeoff configuration. Stop landing, start climbing. The go-around
usually is initiated for instructional purposes, traffic, lack of aircraft
control, weather or surface conditions. The go-around is essentially a
takeoff with full flaps. You must have practiced at altitude so that you
know ahead of time which pressures to anticipate as flaps are retracted
and you maintain level flight. Flap retraction must be carefully
controlled because most training aircraft have little excess power.
The earlier you go-around
the better. This is an action deemed necessary to correct control,
approach, flare, or rollout problems. Altitude allows some trade off for
airspeed. The lower the go-around the more difficult it may seem but this
is not necessarily so. You have less distance to fall in a stall the
closer to the ground you are. This is because flight within ground effect
requires less power for a given performance. The aircraft can fly close to
the ground even with full flaps. In ground effect the partial removal of
flaps is less likely to cause a stall. There is more excess power in
ground effect so that more acceleration can occur as the flaps are
removed.
The successful go-around
is predicated on the pilot's ability to understand the required planning,
set aircraft attitude, clean up the configuration, and the use of power.
The greatest enemy of planning is any form of delay, procrastination or
hesitation. The delayed go-around greatly increases the pucker factor. The
proximity to the ground should not do this but it does. Actually, the
ground proximity should rightly be considered an asset. Ground effect,
properly used, greatly enhances the ability of the aircraft to avoid the
ground, accelerate and climb. Most often go-around accidents are the
result of premature and unintentional climbs at low airspeeds. Airspeed is
money in the bank. Get the airspeed up with full SMOOTH power, a level
attitude or slight dive held against the power and flap effort to raise
the nose, and get off the flaps slowly until reaching climb speed. The
best go-around is a precision control manoeuvre when done properly. Every
move is done in anticipation of what you know will come next. If you don't
know, learn. A pilot's reliability factor can well be measured by the
smoothness with which a go-around is performed.
Reasons the Go-around Is
Difficult:
A safe go-around can be accomplished at any altitude if the initial effort
is just to stay at altitude while power and configuration is adjusted to
allow a climb. The most common fault is attempting to climb before the
aircraft is capable of climbing. Have a go-around plan and fly the plan.
Fly the airplane is # 1.
The go-around is not an emergency, it is a standard procedure even if the
FAA says it is. The go-around is a precautionary option. Properly
performed it is neither difficult or of any particular hazard. You don't
need to tell the tower anything until they ask your intentions. A
go-around should be made when there is a significant deviation from
intentions or a requirement for radical manoeuvring. A go-around is a
sound controlled manoeuvre. Listen for the sound of full power,
acceleration, vy, and climb.
Keep your eyes outside
during the go-around. Keep controls smoothly coordinated and a heading in
a pre-selected direction. Apply full power smoothly, the remove
carburettor heat, anticipate torque, P-factor, and slipstream with right
rudder. Keep the aircraft level with a locked elbow and remove the flaps
judiciously with reference to your airspeed and altitude. There is no need
to hurry. Accelerate to 65 Kts (C-150), trim for climb and set the pitch
attitude that will maintain a Vy climb. Now, you can look at your
instruments.
Raising flaps too quickly
or too much can precipitate a stall. Be gentle. From 40-degree flaps, a
slight removal reduces mostly drag. This is true up to about 20-degrees of
flap. From 15-degrees to no-flaps you are losing mostly lift. Flap removal
by measured stages reduces the change in control forces, change in
attitude, and required pilot reaction. The second most common student
fault in a go-around is failing to use the pre-landing checklist on the
second approach.
Forgetting to bring up
flaps is the most common student fault. Aircraft are certified, when new,
to be able to climb at 2-degrees in normal, utility, and aerobatic
categories with full flaps. Just as old instructors have more trouble
making the climb into an aircraft, so do old airplanes have trouble making
the climbs for which they were originally certificated. The stall during
the go-around is most likely to occur if the aircraft is not allowed to
accelerate in level flight while slowly bringing up the flaps.
As in many flying
situations, instinctive reactions can bite you. Your normal reaction time
to a ballooned landing flare or a bounced landing may create sensations
and flight attitudes that cause problems. Your reaction time of one second
to make the situation worse. You are pushing or pulling on the yoke at the
wrong time. The only correct procedure is to GO-AROUND. Apply full power,
hold the aircraft level, milk up the flaps, stay level to obtain climb
speed, climb out and make a new landing approach.
There is a go-around
situation called 'getting-behind-the-power-curve' that arises when the
go-around is delayed. Behind the power curve means that your angle of
attack is so great that there is insufficient power to climb. Gaining
speed requires a certain loss of altitude. instinctive reactions overcome
training until an obstacle gets so close that both power and instinctive
raising the nose occurs due to perceived danger. The result is a nose
high, low speed, prelude to an accident. A delayed go-around that adds
incremental power changes can create this situation where there is no more
power available and altitude must be surrendered. If the altitude is not
available a go-around is not possible. Get the power off so that a
crash/bounce will not make you airborne and behind the curve at ever a
higher altitude.
When you have been flying
a while, you expect to land...every time. The go-around becomes unusual,
abnormal, and unprepared for. When ATC calls a go-around you are usually
high enough and fast enough to perform without any special anticipation.
The lower and slower you get into the landing procedure the less likely
will you be prepared for the go-around. Do not add additional trim in
anticipation of making the flare attitude easier. Such additional trim
will greatly increase the control pressures and likelihood of a go-around
stall.
A crosswind landing
increases the likelihood of a go-around. Because of the possibility of
uncorrected drift. You don't want to land with side loads on the landing
gear or off runway. The crosswind go-around requires the pilot to make a
change in orientation. While the landing is made with a wing-low heading
parallel to the runway, the go-around requires a wings-level crab heading
at an angle to the runway.
At some airports a
go-around may not be possible due to geographical features. This one-way
airport should never be attempted without good proficiency both in flying
and judging aircraft performance. It is best to overfly at a safe altitude
before making your approach.
Avoiding the Hazards of
the Go-Around
There are several common
faults typical to the go-around. Most problems occur when power is first
added and before flaps are raised.
Remember--The idea that
just adding power to an airplane will make it fly slower is another
example of a flying contradiction. In every other situation in life,
adding power makes things go faster. This phenomenon is best demonstrated
at altitude. Establish the airplane in trimmed low cruise of 70 kts. Add
full power with a touch of rudder to hold heading. The nose will rise and
the aircraft will slow. Do this again without the use of rudder to note
the effect of P-factor. Do it again with flaps and slower airspeeds.
Most control problems
occur in the interval between power application and removal of flaps. The
pitch up and left turning of the nose must be ANTICIPATED and corrected
BEFORE it occurs. Putting more than one finger behind the yoke on a
go-around is a 'probable cause' of over reaction and abrupt control
movements.
For some reason many
students think that the carburettor heat must go off before throttle
application. It doesn't. The throttle should be applied smoothly first and
then the carb heat taken off with the thumb to get full power. The
position of the carb heat control was designed to be pushed in with the
right thumb. A too rapid application of throttle can cause the engine to
load up with excess fuel. This causes a delay in getting full power.
Smooth throttle operation will give smooth engine operation and allow
smoother application of rudder. It is surprising how often students seem
to think that the hand must stay frozen on the throttle to keep it in. It
doesn't. Keep the friction lock of the throttle snug. By holding the
throttle you will fail to get the flaps up. The yoke pressure makes them
think that something is wrong with the trim. There isn't. Once full power
is applied the right hand goes immediately to the flap switch.
Any time an aircraft is
not doing what it is supposed to do where it is supposed to do it during
an approach, go-around. Saving a landing is the lowest form of ego trip a
pilot should ever take. First apply full power, hold a level altitude,
clean up the plane (In ground effect if you can) and climb using Vy.
Finally trim. The go-around is not very intuitive. The pilot must overcome
and counter many concerns and fears. Proximity to the ground is the
'biggie'. However, being close to the ground is the safest place to be.
Performance will be better, you won't fall as far, and you get to see
where you are. Controlled excess speed can get you over an obstacle if
properly utilized.
Go Around Mantra
One mantra for a missed
approach or go-around is:
Power up
Pitch up (level)
Going up
Clean up
I.e. add power, raise the nose, confirm that you have positive rate of
climb established, and then retract gear and flaps. No reason why the same
mantra couldn't be used for a VFR go-around. Learning this a as a
go-around procedure will help in making the transition to the instrument
missed easier.
When to Make a Go Around
About that "jammed the throttle in" phrasing; I'm sure you already know
this, but just in case; NEVER jam in a throttle!! Always use a gentle
progressive hand on a throttle, ESPECIALLY on a go around. As for
when
to initiate a go around; always be prepared to initiate a go around from
ANY position on the approach; during
the flare to a landing attitude, and even after touchdown if it's
necessary and space is available.
There are only three limiting factors for determining a go around;
1. The judgment that it's necessary
2. The room to accomplish it safely.
3. The smarts to complete number 1 at a point that makes number 2 a given!
