What does the term 'angle of attack' refer to?
Answer: The angle between the chord line and the relative wind
Angle of attack is the angle between the wing's chord line and the relative wind.
An aircraft will always stall at the same:
Answer: Angle of attack
A wing always stalls at the same critical angle of attack, though the corresponding airspeed varies.
What is the primary purpose of wing flaps?
Answer: To increase lift and drag for slower approach speeds
Flaps increase both lift and drag, allowing steeper, slower approaches.
Load factor is defined as the ratio of:
Answer: Load supported by the wings to the actual weight of the aircraft
Load factor is the ratio of the load the wings support to the aircraft's actual weight.
During a coordinated level turn, stall speed:
Answer: Increases
Load factor increases in a turn, which raises the stall speed.
What causes an airplane to yaw to the left during takeoff at full power (torque effect)?
Answer: Propeller slipstream, torque, P-factor, and gyroscopic precession
The left-turning tendencies combine torque, P-factor, slipstream, and gyroscopic precession.
Ground effect is most likely to result in which problem?
Answer: Becoming airborne before reaching recommended climb speed
Ground effect reduces induced drag, so the aircraft can lift off before reaching a safe climb speed.
