What is one purpose of wing flaps?
Correct Answer: To enable the pilot to make steeper approaches to a landing
without increasing the airspeed.
One of the main functions of flaps during approach and landing is to:
Correct Answer: Increase the angle of descent without increasing the airspeed.
What is the purpose of the rudder on an airplane?
Correct Answer: To control yaw.
Which is not a primary flight control surface?
A. Flaps
B. Stabilator
C Ailerons
Correct Answer: A. Flaps
The elevator controls movement around which axis?
Correct Answer: Lateral.
1
,Which statement is true concerning primary flight controls?
A. The effectiveness of each control surface increases with speed because there is
more flow over them
B. Only when all three primary flight controls move in sequence do the airflow and
pressure distribution change over and around the airfoil.
C. Primary flight controls include ailerons, rudder, elevator, and trim systems
Correct Answer: A. The effectiveness of each control surface increases with speed
because there is more flow over them.
Which of the following is true concerning flaps?
A. Flaps are attached to the leading edge of the wing and are used to increase wing lift.
B. Flaps allow an increase in the angle of descent without increasing airspeed.
C. Flaps are high drag devices deployed from the wings to reduce lift.
Correct Answer: B. Flaps allow and increase in the angle of descent without
increasing airspeed.
Which device is a secondary flight control?
A. Spoilers
B. Ailerons
C. Stabilators
Correct Answer: A. Spoilers
Trim systems are designed to do what?
2
,Correct Answer: They relieve the pilot of the need to maintain constant back
pressure on the flight controls.
The four forces acting on an airplane in flight are:
Correct Answer: Lift, Weight, Thrust, & Drag
When are the four forces that act on an airplane in equilibrium?
Correct Answer: During unaccelerated flight.
What is the relationship of lift, drag, thrust, and weight when the airplane is in straight-
and-level flight?
Correct Answer: Lift equals weight.
Thrust equals drag.
Which statement relates to Bernoulli's principle?
Correct Answer: Air traveling faster over the curve upper surface of an airfoil causes
lower pressure on the top surface.
The term "angle of attack" is defined as the angle...
Correct Answer: between the wing chord line and the relative wind.
Angle of attack is defined as the chord line of an airfoil and the...
Correct Answer: Direction of the relative wind.
3
, The angle of attack at which an airplane wing stalls will...
Correct Answer: Remain the same regardless of gross weight.
As altitude increases, the indicated airspeed at which a given airplane stalls in a
particular configuration will...
Correct Answer: Remain the same regardless of altitude.
In what flight condition must an aircraft be placed in order to spin?
Correct Answer: Stalled.
During a spin to the left, which wing(s) is/are stalled?
Correct Answer: Both wings are stalled.
How will frost on the wings of an airplane affect takeoff performance?
Correct Answer: Frost will disrupt the smooth flow of air over the wing, adversely
affecting its lifting capability.
Why is frost considered hazardous to flight?
Correct Answer: Frost spoils the smooth flow of air over the wings, thereby
decreasing lifting capability.
How does frost affect the lifting surfaces of an airplane on takeoff?
