AVIT 323 block 12- Dilse UPDATED Exam
Questions and CORRECT Answers
Define adverse yaw - CORRECT ANSWER - The tendency of an airplane to yaw away
from the direction of aileron roll input
-aileron deflection causes it
Define overbanking tendency - CORRECT ANSWER - When the top wing moves faster
than the bottom wing causes a banking tendency
In a 60 degree bank turn, what happens to the aircraft - CORRECT ANSWER - -a 3000
pound aircraft will act like a 6000 pound aircraft
-2 G's will be pulled
Definition of load factor - CORRECT ANSWER - -the ratio between the lift and the
weight of an aircraft.
Load Factor = Lift / Weight (expressed in number of "Gs")
Definition of safety factor - CORRECT ANSWER - describes the structural capacity of a
system beyond the expected loads or actual loads
-Safety factor is the ultimate load factor
Definition of ultimate load factor - CORRECT ANSWER - -the Limit Load multiplied by
a prescribed Safety Factor of 1.5
Definition of limit load factor - CORRECT ANSWER - -the maximum load factor
authorized during flight
What affects the radius and rate of a turn - CORRECT ANSWER - Bank and Airspeed
, Static stability - CORRECT ANSWER - -INITIAL tendency to return to the equilibrium
condition following a disturbance
Types of static stability - CORRECT ANSWER - -Positive: when it goes back to trimmed
state
-Neutral: stays at the disturbance attitude
-Negative: changes to a more dramatic attitude once disturbed
Dynamic stability - CORRECT ANSWER - -TIME HISTORY of an aircrafts response to a
disturbance
-In order to have any type of dynamic stability, you must have positive static stability.
Longitudnal stabilty - CORRECT ANSWER - up/down
Pitch stability:
-ALONG the longitudinal
-AROUND the lateral axis
Forward CG - CORRECT ANSWER - -Poor performance
Greater distance between the elevator and the CG, making the TDF greater, therefore needing
more lift.
Greater lift required, more drag= slower AS
Aft CG - CORRECT ANSWER - -Better performance
Smaller distance between the elevator and the CG, making the TDF Less, therefore needing less
lift.
Less lift required, Less drag= greater AS
Directional stability - CORRECT ANSWER - Yawing left/right
Yaw stability:
