AVIT 323 EXAMS SET COMPREHENSIVE
QUESTIONS AND SOLUTIONS HIGH SCORE
PREPARATION

●● Definition of a stall
Answer: Exceeding the critical angle of attack


●● Coefficient of lift
Answer: -The ratio between dynamic pressure and lift pressure
DOES NOT CHANGE WITH:
-Weight
-CG
-Aircraft pitch attitude (think AOA)
-Or Aircraft weight


●● Angle of indicence
Answer: Chord line related to the longitudinal axis


●● Negative AOA
Answer: More lift on the bottom of the airfoil

, ●● Positive AOA
Answer: More lift on the top of the airfoil


●● AOA differs with
Answer: ›Pitch Attitude
›Altitude
›Weight
›Speed


●● High density altitude
Answer: High altitude, air is thinner so lift is decreased


●● Low density altitude
Answer: Low Altitude, thick air, good for flight performance.


●● Types of parasite drag
Answer: -form drag (Separation drag)
-skin friction drag (viscus drag)
-Interference drag (produces two boundary layers 1+1=3)
-Profile drag (combo of skin friction and form drag)
-Cooling drag
-Leakage drag
