Stability and Controllability

Question 1

An airplane is said to be inherently stable will:

Answer 1

require less effort to control

Question 2

The longitudinal stability of an airplane is determined by:

Answer 2

the location of the CG (center of gravity), with respect to the center of lift

Question 3

Loading an airplane to the most AFT CG limit will cause:

Answer 3

the airplane to be less stable at ALL speeds

Question 4

If an airplane is loaded AFT of the AFT CG limit, the pilot might experience:

Answer 4

difficulty in recovering from a stalled condition

Question 5

The nosedown pitch tendency of an airplane when power is reduced (except in T-Tail airplanes), occurs because:

Answer 5

the downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced

Question 6

Changes in the center of pressure of a wing affect:

Answer 6

the aircraft’s aerodynamic balance and controllability

Question 7

Aft means

Answer 7

Tail of the aircraft
