PPL Aeronautical Knowledge 2

Question 1

What does the term 'angle of attack' refer to?

Accepted Answer

The angle between the chord line and the relative wind

Answer

The angle between the wing and the horizon

Answer

The pitch attitude shown on the attitude indicator

Answer

The angle between the longitudinal axis and the ground

Question 2

An aircraft will always stall at the same:

Accepted Answer

Angle of attack

Answer

Airspeed regardless of attitude

Answer

Power setting

Answer

Altitude

Question 3

What is the primary purpose of wing flaps?

Accepted Answer

To increase lift and drag for slower approach speeds

Answer

To increase cruise speed

Answer

To reduce stall angle of attack

Answer

To improve fuel efficiency

Question 4

Load factor is defined as the ratio of:

Accepted Answer

Load supported by the wings to the actual weight of the aircraft

Answer

Thrust to drag

Answer

Total weight of aircraft to fuel weight

Answer

Lift to thrust

Question 5

During a coordinated level turn, stall speed:

Accepted Answer

Increases

Answer

Decreases

Answer

Remains the same

Answer

Drops to zero

Question 6

What causes an airplane to yaw to the left during takeoff at full power (torque effect)?

Accepted Answer

Propeller slipstream, torque, P-factor, and gyroscopic precession

Answer

Adverse yaw only

Answer

Crosswind from the right

Answer

Excessive right rudder

Question 7

Ground effect is most likely to result in which problem?

Accepted Answer

Becoming airborne before reaching recommended climb speed

Answer

Reduced lift on takeoff

Answer

Increased induced drag near the ground

Answer

A steeper stall angle
