AERODYNAMICS EXAM QUESTIONS
AND ANSWERS
Does the angle of attack at which an airplane wing stalls change with differing
weights? - ANSWER-No, remains the same regardless of weight
Does altitude at a given airspeed effect the airspeed at which an airplane will stall? -
ANSWER-No altitude does not effect the airspeed at which an airplane will stall
What is required for spin to occur? - ANSWER-The airplane must stall
During a spin to the left, are both wings stalled, or just one wing? - ANSWER-Both
wings
How will frost on the wings affect takeoff performance? - ANSWER-Disrupt smooth
flow of air over the wing, affecting its lifting capability and prevent liftoff at normal
speed.
Airplanes have a ___-turning tendency causing the pilot to have to hold more ___
rudder. - ANSWER-Left....Right
What is P-factor - ANSWER-Asymmetric propeller loading - causing the airplane to
yaw to the left
Why does P-factor cause yawing to the left? - ANSWER-The descending Right
propeller blade takes a greater bite of air than the ascending blade on the left,
therefore producing more thrust on the R side. Thus it yaws to the left.
Torque effect (left turning tendency) is greatest at ___ airspeed, __ power, and ___
angle of attack. - ANSWER-low airspeed, high power, and greater angle of attack
T/F: at higher speeds, there isn't as much of a left turning tendency because
airplanes are built with the left wing having a greater angle of attack. - ANSWER-
True
The ___ stability of an airplane is determined by the location of CG with respect to
the center of lift. - ANSWER-longitudinal
Loading airplane to the most aft (rearward) CG limit will make the plane __ stable at
all speeds - ANSWER-less
T/F: If an airplane is loaded aft of the aft CG limit, it will be difficult to recover from a
stalled condition - ANSWER-true
The tendency for nose-down pitch to occur when power is reduced is because ___ -
ANSWER-The decreased downwash from the propeller slipstream on the elevators
