School Marm
With an Attitude
Connie Edwards,
long time sparkplug of the warbird movement
and quintessential Texan is credited with
saying, "Start out in a Bearcat, transition
to the P-51 and then you're ready for the
T-6."
Edwards was referring to
the T--6's less-then-spotless reputation for
ground handling. And he's right. Many
civilians transitioning into fighter
aircraft are amazed at how much easier
fighters are to handle (in most situations,
anyway) then the old Texan, a supposedly
easily-tamed "trainer." When I got my chance
to fly Mustangs, I was amazed and relieved
to find this was absolutely the case. If the
P-51 had been the quantum jump up from the
T-6 in ground handling difficulties that it
was in aerial performance, my first Mustang
hop would have culminated in a spectacular
fire at the edge of the runway. Even if I
kept control and survived the flight, I
would have drowned in post-flight adrenaline
flow. Obviously it didn't happen that way
because the Mustang was such a pussy cat
compared to the Texan.
I can't speak for others,
but the Six had me so wired for abysmal
ground handling that the Mustang was a
breath of fresh air. There was nothing that
big bird could do that would surprise me.
Yes, "relieved" is definitely the right
word.
My reaction to the Six
was probably typical and definitively
indicative of what the old school marm
represents...the epitome of the
higher-performance trainer. It wasn't
supposed to be easy to fly. It was not,
repeat not, supposed to take a student out
and give him a good time. By the same token,
the Texan wasn't supposed to present him
with impossible tasks either. And it didn't.
What the AT-6 (SNJ to you Navy types)
represented, and still represents, was the
finest combination of challenges ever built
into a military trainer. The student had to
fly the airplane, reading its every nuance.
His proficiency benefited from this mental
and physical exertion. He got better whether
he wanted to or not!
The best
indication of how good a trainer the Texan
was/is can be seen by the fact that here we
are forty years into the jet age and there
are still countries around the world using
the North America aerial classroom as
first-line trainers. As recently as five
years ago, major air forces still used it
and it is the updating of those air forces
which has pumped so many surplus T-6s into
the American civilian market.
A specialty industry has
developed to support and sell the T-6/SNJ/Harvard.
Part of this industry has worked to bring
back as many Texans as possible from
overseas where they are being retired. Ray
Stutsman of Elkhart, Indiana brought back a
herd or two of Spanish T-6s while others are
working on bringing back the South African
birds. Prices vary wildly, ranging from
$20,000 to $60,000 with $30-$35,000 giving
you a fairly clean airplane with lots of
time left on the P&W R-1340. As is usually
the case, you get what you pay for.
(Editor's Note From the Year 2000: Budd, you
dummy, you should have bought a couple
dozen, when you could. Just quadruple those
prices and you'll be close to today's
prices)
I am not a high-time
Texan driver. Without digging through logs
and adding up all the numbers, I'd say my
time spent in the cavernous cockpit would
barely top 100 hours, all of it civilian. Of
that time, at least half was in the back
seat either receiving dual time (in
preparation for bigger birds with longer
noses) or giving dual to Texan owners who
wanted to know how to land/spin/aerobat
their airplane. I'm not the definitive
authority on T-6 performance and handling. I
am, however, pretty typical of the average
civilian pilot who is lucky enough to find
himself strapped into one of the biggest
pieces of iron commonly available to us. My
viewpoint is grassroots . . . and reasonably
current.
Oddly enough, I'm not
sure where I flew my first T-6. It may have
been the D model operated by Flight Safety
out of Vero Beach, Florida. But while I'm
hazy where my first T-6 time came from,
there's no doubt where I spent the most
instructive time in the Texan: at Junior
Burchinal's Warbird school in Paris, Texas,
during the early 1970s. I've put a lot of
time into T-6s since then and I've enjoyed
all of them more than I enjoyed those with
Junior. I can, however, guarantee I've never
learned more than in those ten hours with
Junior. He believes firmly in working your
buns off for your own good. And it worked.
When you climb into the
front hole of the T-6 it feels like a
fighter. I've said this before, many times,
but it's true. And one reason it feels like
a fighter is because North American designed
the Texan to give the student the feel and
controls of a big bird with less speed and a
more forgiving nature.
Describing the cockpit of
a T-6 is like describing a cockpit of most
World War Two fighters (especially North
Americans), although it is quite a bit
larger than something like a Bearcat.
Beneath your left arm are all of the primary
accessory controls, i.e. elevator, aileron,
and rudder trims, as well as the landing
gear and flap actuators. All of the
electronic and radio goodies are on a
console by your right arm.
You have to dig deep to
find the visual differences between a T-6
and SNJ and to differentiate the models of
Sixes, which the Air Force, adopted. One
sure clue of a SNJ or an early T-6 is a tail
wheel lock sticking out of the left side of
the canopy rail. Later T-6s had steerable
tail wheels similar to the Mustang, which
unlocked when you pushed the stick forward.
Supposedly this feature was on later Ds, all
Gs and the Canadian-built Harvards IV's
while earlier models and all SNJs had tail
wheels that were either locked straight
forward or free swivel depending on the
position of the control in the cockpit.
Another noticeable difference in the later
airplanes is the lack of a large cutout in
the upper right hand side of the instrument
panel; In SNJs and earlier model Sixes, a
provision was made to mount a .30 caliber
machine gun and the receiver stuck through
the instrument panel. The later airplanes
also eliminated the inertia starter, so the
energize and engage pedal between the
rudders may or may not be there. SNJ's and
early airplanes also have a separate
hydraulic actuation lever by your left knee.
In actuality there were a
ton of minor differences between all the
models but only the steerable tailwheel and
the late model servo-tabs on the ailerons
(which really do make the airplane much
nicer to fly) are noticeable.
Cranking up a round
engine is one of the world's true sensual
delights and it's made even more so if an
inertia starter is being used. The whine of
the starter winding up and the descending
mechanical growl of engagement are right out
of a late night movie sound track. And, of
course, as the engine coughs into life,
blowing smoke and noise past your elbows,
which are sticking out over the canopy
rails, the mechanical nostalgia gets even
deeper.
Canopy back, "S" turning
your way out to the runway, there's no doubt
you are working with a big piece of iron. As
you roll out on to the centerline, double
checking to make sure the tailwheel is
locked, you bring the power up smoothly and
wait for the 600 horses to start shoving all
that sheet metal down the runway. Many
airplanes accelerate much faster than a Six
and because of sheer size the Texan feels
almost as if it is lumbering along. Your
visibility isn't nearly as bad as expected,
only the centre portion of the runway is
blocked, so it is relatively simple to ease
rudder one way or the other to keep tracking
straight.
As
soon as the power is against the stop, the
tail is picked up gently (repeat, gently)
and the airplane will fly off with little or
no provocation from the pilot who thinks
he's in command. Hoist the tail vigorously
and you'll get a surprisingly quick swing to
the left as the gyroscopic precession of the
prop kicks in.
At this point I always
have to remind myself what model of Six I'm
flying, since retraction of the landing gear
requires an extra step in the earlier birds.
In the late models, you just jerk the gear
handle (that's down by your left knee) in
and up. In earlier Sixes and most SNJs,
however, you have to first activate the
hydraulic system by pushing down on a power
lever which gives you juice for something
like thirty seconds. At least once I thought
a T-6 was a real turkey in climb, then
looked down at my shadow and saw that the
gear was still out. Dumb!
Setting up climb power at
30 inches and 2000 rpm you can just sit back
and watch as the world gradually falls away.
While the rate of climb isn't going to do
much to amaze you, the feeling that comes
over you will. You find yourself drifting
into a military mental mode, since there is
nothing about the airplane that even vaguely
reminds one of a civilian airplane.
Absolutely nothing! The Texan is hardcore
military and the only difference between the
Six and a fighter is the number on the
airspeed gauge is much lower. Numbers are
only numbers. If you don't have telephone
poles whizzing past to give numbers some
scale, they are totally abstract, so you can
play fighter pilot to your hearts content in
a Six.
I dearly love to aerobat
the Six, although I'll have to admit that
since my chicken quotient is much higher
than my talent quotient I keep a healthy
amount of air between me and the hard stuff
below . . . like 6,000 feet for instance. At
that altitude, a Six will only be indicating
160-170 mph (depending on how clean the
airplane is and how much the airspeed lies),
so I'll drop the nose and get 180 on the
clock while centering a point on the horizon
in the windshield. Rolling forty-five
degrees to the right, I pull the nose up
into a giant barrel roll to the left,
keeping my reference point dead in the
centre of the roll. The Six loves those
kinds of manoeuvres . . big smooth ones.
It's so stable in all regimes that it
literally grooves through rolls as if on
rails.
The loops are the same.
The Six seems like it takes forever to find
the way up and over the top, chugging away
like a locomotive headed for Peoria.
The T-6 has some good/bad
habits that make it an excellent trainer.
One of these is the ability to unload in an
accelerated stall, if you don't pay
attention to the almighty airspeed/G-force
relationship something I always keep in the
back of my mind when I'm twisting the
airplane's tail.
The Texan stalls clean
somewhere in the neighbourhood of 70 mph but
the addition of G and/or bank angle can run
that up rapidly. I love to show students
that capability by pulling a bit too hard on
the top of a loop. The airplane will gently
stall and do a half-snap to right side up
and will continue into a spin if you wait
too long to release the back pressure.
You can see the same type
of stall performance in a tight turn. I have
the student pull into a tight turn to the
left, increasing back pressure as the speed
burns off. Somewhere along the line the
airplane will decide it's had enough and do
a half snap to the outside (if the ball is
centered) in one of the prettiest vertical
reverses you've ever seen. If the ball is
shoved to the outside, however, the Six will
snap to the inside and you'd better have a
little altitude to recover.
Accompanying
this ability to unload when you least expect
it is a definite appetite for secondary
stalls. If you spin the airplane or stall in
any way, you absolutely have to allow time
to accelerate and not put on any G until the
Six has enough speed to support flight. It's
really easy to accidentally spin the
airplane while dog fighting and get anxious
on the recovery, causing a secondary stall
and a spin in the other direction. This has
killed more than a few experienced pilots
who are goofing around without the
obligatory cushion of extra altitude.
Don't construe
these stall characteristics as being bad.
Yes, the T-6 will bite you but it will do so
the same way every time. It's totally
predictable. You get slow and pull and the
Texan lets you have it right now! Those
areas where the Six tends to get fiesty are
those areas where light handed flying is
required. A little attention to the speed/G
relationship will keep you out of trouble
all together. In other words, you have to
learn to fly the airplane . . . which is the
true test of a trainer in the first place.
One of the neatest things
about the Texan is to be sitting there just
chugging along at altitude, pretending the
world is still at war. You are surrounded by
a flat-black and zinc chromate green world
that's awash in a sea of cryptic placards.
You sit quite high in the airplane, well
over the nose, and you are very conscious of
protruding up into a greenhouse enclosure
with cockpit framing everywhere you look.
Your feet are stretched out to either side
of the stick, resting in giant trays with
equally giant rudder pedals at the forward
end. Even the simplest task, like checking
the fuel, reminds you that you are astride
an anachronistic military animal . . . the
fuel gauges are on the floor on either side
of the seat. Often you have to shade your
eyes to see down into the bowels of the
airplane.
Every time I get ready to
land a Six I can feel my mouth start to turn
to dust, a trait experienced Six drivers say
is good. At least I'm not over-confident (an
understatement), since most of the Six's
reputation for being cantankerous comes from
the landing phase.
Throwing the gear out on
downwind, you check the gear lights, but you
also squint to see through little plexiglass
windows on the top of each side of the wing
center section. It's only by checking to see
that the locking pins are secure that you
know for sure the gear is locked down. Then
you set up what is fairly normal approach
planning to have 90 mph on final, by which
time you'll have all 45 degrees of flap out.
The flaps are split trailing edge affairs
rather than true-hinged surfaces, so they
generate as much drag as they do lift. This
puts your nose down and gives you tremendous
visibility on final.
As a normal
rule, I'll opt for a three-point landing and
I slide my feet up high on the rudder pedals
to give mechanical advantage on the brakes
should I need them. Actually, the only
assumption you can make about a T-6 at all
is that it is going to swerve one way or the
other and you can't be sure which way. So
you plan accordingly, getting your nerves
and feet ready to handle whatever it dishes
out. The results of a bad swerve can be
really exciting-like crumpled wings, folded
landing gear, etc. If you do it really
right, you'll be awarded with a view of the
airport from an upside down position
alongside the runway. The trick is to catch
the swerves right at the beginning while
they are still tiny turns. Nip each of those
in the bud and the airplane is absolutely no
problem. It only gets nasty, if you let the
nose wander too far before getting your feet
in the act.
The machine wheel lands
quite easily, which is what most folks do
these days. However, the swerving tendency
is still there and you have to be wide awake
as the tail settles because it just loves to
meander as the wind goes out of the rudder.
I've always found G
models and Harvard Mk. IVs easier to land,
probably because of the steerable tail-wheel
but that may be an illusion brought about by
coincidence and luck.
A lot of folks think
they'll never get a chance to fly a real
Warbird. With the numbers of actual combat
aircraft dwindling down to nothing, it's
easy to overlook the fact that there are
between 500 to 600 T-6s running around the
country. That number is increasing everyday
and the T-6 is just as much Warbird as
anything that totes along a half dozen .50
calibres. More important, you can go a
lifetime without finding a Mustang owner
willing to give or sell you a ride. But the
possibility of some free fuel and a couple
of cool ones can tempt many a T-6 owner into
letting rag legs like you and me into the
backseat. There you aren't cooped up in a
hot, sweaty, noisy, little box as you are in
the back of a P-51 . . . strictly a
passenger in a cement mixer. In the back of
a T-6 you are still a pilot and can actually
fly the airplane. You can put your hands on
forty years of history and get a feel for
the way it was.
One note of caution: like
any Warbird the T-6 is a high-performance
machine possessed of high-performance quirks
and maintenance. So don't go up with just
any T-6 driver since the law of averages
says there's bound to be at least a few who
don't get enough time to stay truly
proficient. Don't be afraid to ask around
before jumping in with someone who may or
may not be as good as he or she thinks they
are.
In a T-6 you get the same
nostalgic rush most Warbirds give, only the
raw edged performance is missing. Most of
that performance, however, is measured only
by numbers on a dial.
Maybe T-6 owners should
repaint their airspeed indicators! |
