What this covers

Sample questions

What is the angle of attack of a wing?

  1. The angle between the chord line and the horizon
  2. The angle between the wing and the fuselage centerline
  3. The angle between the flight path and the ground
  4. The angle between the chord line and the relative wind
Show the answer

D. The angle between the chord line and the relative wind

Angle of attack is measured between the wing's chord line and the oncoming relative wind. The angle to the horizon is pitch attitude, which can differ greatly from angle of attack.

What is load factor?

  1. The load the wings support divided by the aircraft's weight
  2. The aircraft's weight divided by its total wing area
  3. The battery weight divided by the total takeoff weight
  4. The payload weight divided by the aircraft's empty weight
Show the answer

A. The load the wings support divided by the aircraft's weight

Load factor is the ratio of the lift the wings must produce to the actual weight of the aircraft, expressed in G. Weight divided by wing area is wing loading, a different quantity.

Reference: FAA-H-8083-25, Chapter 5

A fixed-wing unmanned aircraft holds altitude while its bank angle is increased. What happens?

  1. Load factor and stall speed both increase
  2. Load factor and stall speed stay the same
  3. Load factor increases; stall speed decreases
  4. Load factor decreases; stall speed increases
Show the answer

A. Load factor and stall speed both increase

In a level turn the wings must supply extra lift to balance weight and turn the aircraft, so load factor rises with bank. A higher load factor raises the speed at which the wing stalls.
