pitot tube
Measuring instrument consisting of a combined Pitot tube and static tube that measures total and static pressure; used by the aircraft to measure airspeed.

left aileron
These surfaces, located on the outside trailing edges of the wings, control the airplane around its longitudinal axis, i.e., the degree of bank or whether one wing is higher or lower than the other wing.

undercarriage shock absorber
aircraft use different systems but may be made of rubber disks or shock cord

left wing
Provides lift by creating a low pressure area on the top of the wing and a high pressure area on the bottom. The top of the wing is curved, which provides a longer distance for air to flow over the wing than under the wing. As the air on top of the wing travels a further distance, it moves faster than the air flowing under the wing, which results in less pressure on top than on the bottom of the wing. At the same time, the bottom of the wing deflects air downward, which also produces lift.

main landing gear
The component of the airplane that touches the runway first during a normal landing. It is stressed to take large loads and impacts.

right wing leading edge
Provides lift by creating a low pressure area on the top of the wing and a high pressure area on the bottom. The top of the wing is curved, which provides a longer distance for air to flow over the wing than under the wing. As the air on top of the wing travels a further distance, it moves faster than the air flowing under the wing, which results in less pressure on top than on the bottom of the wing. At the same time, the bottom of the wing deflects air downward, which also produces lift.

right aileron
These surfaces, located on the outside trailing edges of the wings, control the airplane around its longitudinal axis, i.e., the degree of bank or whether one wing is higher or lower than the other wing.

propeller
Propellers may be classified as to whether the blade pitch is fixed or variable. Fixed propellers are used mostly on microlights. The propeller blades are themselves aerofoils and this is what produces the thrust when rotating. The demands on the propeller differ according to circumstances. For example, in takeoffs and climbs more power is needed, and this can best be provided by low pitch. For speed at cruising altitude, high pitch will do the best job. A fixed-pitch propeller is a compromise.

skid
protects the tail in the event of contact with the ground

rudder
This surface, which is connected to the vertical stabilizer, moves the airplane around its vertical axis and is used to yaw (move the tail to the left or right) the airplane. The rudder is attached to the vertical stabilizer -- This surface provides directional (right or left) stability. It acts like a weathervane.

spinner
This smooths the air to give optimum flow to the propeller

Horizontal stabilizer
This structure, located in the rear of the airplane, is designed to provide continuous longitudinal (from front to rear) stability.

elevator
A movable part on the rear of the horizontal stabilizer. It is used to move the airplane about the lateral axis. It provides the input of pitch and helps control altitude.

wing strut
supports the wing structure. This may be absent on more advanced aircraft

radio antenna
this can be mounted in a number of places

nose gear
This component is designed to steer the airplane on the ground. It is not stressed for excessive impacts or loads. However, it is designed to carry the weight of the forward portion of the airplane.

engine
microlight engines can be water or air cooled. The popular water cooled Rotax series is often used. These can be 4 or 2 stroke. 2 stroke engines have a poorer record for reliability but are lighter for a given power output.
