ANSWERS GRADED A+
Which device is a secondary flight control?
A. Spoilers
B. Ailerons
C. Stabilators
A. Spoilers
Trim systems are designed to do what?
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:
Lift, Weight, Thrust, and Drag
When are the four forces that act on an airplane in equilibrium?
During unaccelerated flight
What is the relationship of lift, drag, thrust, and weight when the airplane is in
straight-and-level flight?
,Lift equals weight
Thrust equals drag
Which statement relates to Bernoulli's principle?
Air traveling faster over the curve upper surface of an airfoil causes lower pressure
on the top surface

Between the wing chord line and the relative wind
Angle of attack is defined as the chord line of an airfoil and the...
Direction of the relative wind
The angle of attack at which an airplane wing stalls will...
Remain the same regardless of gross weight
As altitude increases, the indicated airspeed at which a given airplane stalls in a
particular configuration will...
Remain the same regardless of altitude
,What is one purpose of wing flaps?
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...
Increase the angle of descent without increasing the airspeed
What is the purpose of the rudder on an airplane?
To control yaw
Which is not a primary flight control surface?
A. Flaps
B. Stabilator
C Ailerons
A. Flaps
The elevator controls movement around which axis?
Lateral
Which statement is true concerning primary flight controls?
, A. The effectiveness of each control surface increases with speed because there is
more airflow 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.
A. The effectiveness of each control surface increases with speed because there is
more airflow 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.
B. Flaps allow an increase in the angle of descent without increasing airspeed
In what flight condition must an aircraft be placed in order to spin?
Stalled
During a spin to the left, which wing(s) is/are stalled?
Both wings are stalled
How will frost on the wings of an airplane affect takeoff performance?
