PAR exam Flight Theory-with Complete
Solutions 100% Verified | Updated Questions
Why does increasing speed also increase lift? - ANSWER The increased impact of the
relative wind on an airfoil's lower surface creates a greater amount of air being
deflected downward.
What is the purpose of an elevator trim tab? - ANSWER Modify the downward tail load
for various airspeeds in flight eliminating flight-control pressures.
The left turning tendency of an airplane caused by P-factor is the result of the - ANSWER
Propeller blade descending on the right, producing more thrust than the ascending
blade on the left
When are the four forces that act on an airplane in equilibrium - ANSWER During
unaccelerated flight
What force makes an airplane turn - ANSWER The horizontal component of lift
Four forces acting on an airplane in flight - ANSWER lift, weight, thrust , drag
What type of drag is the result of the production of lift? - ANSWER induced drag
What is the purpose of ailerons on an airplane? - ANSWER to control roll
The amount of excess load that can be imposed on the wing of an airplane depends
upon the - ANSWER speed of the airplane
, What is the relationship between centrifugal force and the horizontal lift component in
a coordinated turn - ANSWER Horizontal lift and centrifugal force are equal
Additional back pressure may be required during a turn because - ANSWER the bank
results in a reduced vertical lift component
When airspeed is increases in a turn, what must be done to maintain a constant altitude
- ANSWER increase the angle of bank and/or decrease the angle of attack
In theory, if the angle of attack and other factors remain constant and the airspeed is
doubled, the lift produced at the higher speed will be - ANSWER four times greater than
at the lower speed
What is ground effect - ANSWER The result of the interference of the surface of the
Earth with the airflow patterns about an airplane.
What is the relationship of lift, drag, thrust, and weight when the airplane is in straight-
and-level flight - ANSWER lift equals weight and thrust equals drag
The purpose of an anti-servo tab is to - ANSWER increase the force required to move the
control surface
The purpose of a servo tab is to - ANSWER reduce the force required to move the
control surface
During a steady climb, the angle of climb depends on - ANSWER excess thrust
The angle of attack of a wing directly controls the - ANSWER distribution of pressures
acting on the wing
