ACTUAL Exam Questions and CORRECT
Answers
Air flowing over the top of the wing moves...? - CORRECT ANSWER - Faster



Which part of the airfoil has relatively low pressure? - CORRECT ANSWER - Top side of
airfoil


Which part of the airfoil has relatively high pressure? - CORRECT ANSWER - Bottom
side of airfoil


What creates lift? - CORRECT ANSWER - High pressure below the wing, with low
pressure above the wing
The pressure differential is what creates lift


What is the Angle of attack? - CORRECT ANSWER - The angle between chord line and
relative wind


The angle of attack directly controls? - CORRECT ANSWER - Lift, drag and airspeed



When AOA is increased, what factors increase? - CORRECT ANSWER - Lift and drag
are increased


Critical angle of attack? - CORRECT ANSWER - Highest AOA where air flows smoothly
over the wing


Laminar flow? - CORRECT ANSWER - a smooth airflow over the airfoil

,A loss of laminar flow over the wing results in...? - CORRECT ANSWER - A stall



The AOA of wing directly controls the...? - CORRECT ANSWER - Distribution of
pressures acting on a wing


In unaccelerated flight, there is a corresponding indicated airspeed for every...? - CORRECT
ANSWER - AOA to generate lift



At higher altitudes, the airplane must be flown at a higher...? - CORRECT ANSWER -
TAS for any given AOA


Reaching the critical AOA means the wing will...? - CORRECT ANSWER - Continue to
have smooth airflow


Critical AOA is the same regardless of...? - CORRECT ANSWER - Weight
Dynamic pressure
Bank angle
Pitch attitude


Indicated stalling speeds are affected by...? - CORRECT ANSWER - Weight
Load factor (G's)
Power


The Critical angle of attack never...? - CORRECT ANSWER - Changes


The airplane will always stall at the same Critical AOA, but changes in weight, load factor and
power will result in the aircraft reaching the CAOA at a...? - CORRECT ANSWER -
Lower indicated airspeed

,Will turbulence change your stall speed? - CORRECT ANSWER - Yes, it changes load
factor


Frost on the wing will cause the airplane to stall at an AOA...? - CORRECT ANSWER -
Lower than normal


Wing planforms? - CORRECT ANSWER - The shape and layout of the wing



Rectangular wing planforms tend to stall...? - CORRECT ANSWER - Near the root, with
the stall progressing to wingtips


The need to slow aircraft below Va is brought by which weather phenomenon? - CORRECT
ANSWER - Turbulence, with an increase in stall speed



The stalling speed of an airplane is most affected by...? - CORRECT ANSWER -
Variations in airplane loading


Primary flight controls? - CORRECT ANSWER - Ailerons, Rudder, Elevator



Secondary flight controls? - CORRECT ANSWER - Flaps
Trim


What is the main purpose of flaps? - CORRECT ANSWER - Provide same lift at slower
airspeed


What affect do flaps of have aerodynamic ability? - CORRECT ANSWER - Increased
drag
Increased lift

, What is the purpose of trim? - CORRECT ANSWER - To relieve control pressures



Trim tab? - CORRECT ANSWER - Maintains same position relative to elevator



Servo tab? - CORRECT ANSWER - Moves in opposite direction of movement
assists in moving primary control surfaces


Anti servo tab? - CORRECT ANSWER - Tab moves in same direction as control surface
Prevents control surface from moving full deflection


What is the purpose of spoilers? - CORRECT ANSWER - Increase Drag to slow down



Four forces working on an aircraft? - CORRECT ANSWER - Thrust
Drag
Lift
Weight


Thrust? - CORRECT ANSWER - The force applied to propel an object in a certain
direction


Drag? - CORRECT ANSWER - Force that acts parallel to both relative wind and flight
path of aircraft


Lift? - CORRECT ANSWER - Force perpendicular to relative wind



Weight? - CORRECT ANSWER - Acts towards the center of the Earth



In steady flight, the forces are are...? - CORRECT ANSWER - Equal to each other
