1.8 airplane stability

Question 1

what determines the longitudinal stability of an airplane

Answer 1

the location of the CG with respect to the center of lift

Question 2

an airplane said to be inherently stable will

Answer 2

require less effort to control

Question 3

changes in the center of pressure of a wing affect the aircraft’s

Answer 3

aerodynamic balance and controllability

Question 4

an airplane has been loaded in such a manner that the CG is located aft of the aft CG limit. one undesirable flight characteristic a pilot might experience with this airplane would be

Answer 4

difficulty in recovering from a stalled condition

Question 5

What causes an airplane (except a T-tail) to pitch nose down when power is reduced and controls are not adjusted

Answer 5

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

Question 6

What is the effect of advancing the throttle in flight

Answer 6

Both aircraft groundspeed and angle of attack will increase

Question 7

loading an airplane to the most aft CG will cause the airplane to be

Answer 7

less stable at all speeds

Question 8

an airplane loaded with the center of gravity (CG) rear to the aft CG limit could

Answer 8

increase likelihood of inadvertent overstress
