Aircraft Flashcards
Piper 28
P28A
Low wing
Cessna 172
High wing
4 strokes of piston engine
Intake stroke - Induction
Compression stroke
Combustion stroke - Power
Exhaust stroke
Primary flight controls
Ailerons - Longitudinal, Roll
Elevators - Lateral, Pitch
Rudder - Vertical, Yaw
Secondary flight controls
Slats -
Flaps
Spoilers
Trim tabs
Speed brakes
Slats
Extension on the leading edge of a wing
Allow the wing to operate at higher angle of attack
Flaps
Mounted on trailing edge
Deflects down to increase lift - reduce stalling speed
And increase drag - act as air brakes
Spoilers
Extends upwards to reduce lift and increase drag
Trim tabs
Adjust the resting position of control surface
Stabilise pitch
Speed brake
Parachute behind
Pitot-static system
Measures pressure and pressure differences
• Air speed indicator (Both)
• Altimeter (Only static)
• Vertical speed indicator (only static)
4 powers affecting an aircraft
Thrust
Drag
Lift
Weight
Parasite drag
Skin friction - actual contact of air particles against the surface of the aircraft
Form drag - caused by separation of air that is flowing over the aircraft or airfoil
Interference drag - caused by the interaction of two aerodynamic bodies
Total drag
Parasite drag + induced drag
Angle of climb
Altitude gained relative to distance
Calibrated and indicated air speed is the same
True
TAS had nothing to do with IAS
True
Rate of climb
Altitude gained by time
(Think sim)
