GLEIM Unit 1: Airplanes and Aerodynamics
With complete solutions
What is one purpose of wing flaps? ANS✔✔ 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: ANS✔✔ Increase the angle of descent without
increasing the airspeed
What is the purpose of the rudder on an airplane? ANS✔✔ To control yaw.
Which is not a primary flight control surface? ANS✔✔ Flaps
The elevator controls movement around which axis? ANS✔✔ lateral axis
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 ANS✔✔ A is correct because the rudder,
aileron and elevator effectiveness increases with speed due to increased airflow over the surface of the control device
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 ANS✔✔ Answer (B): Flaps allow an increase in the
angle of descent without increasing airspeed.

Explanation: Flaps are attached to the trailing edge of the wing and are used during approach and landing to increase
wing lift. This allows an increase in the angle of descent without increasing airspeed.
Which device is a secondary flight control?
A. Spoilers
B. Ailerons
C. Stabilators ANS✔✔ Spoilers
Trim systems are designed to do what?
A. They relieve the pilot of the need to maintain constant pressure on the flight controls
B. They are used during approach and landing to increase wing lift
C. They move in the opposite direction from one another to control roll ANS✔✔ A: is correct, also note that Trim
systems include trim tabs, anti-servo tabs, and ground adjustable tabs
The four forces acting on an airplane in flight are: ANS✔✔ lift, weight, thrust, and drag
When are the four forces that act on an airplane in equilibrium? ANS✔✔ During unaccelerated level flight
What is the relationship of lift, drag, thrust, and weight when the airplane is in straight-and-level flight? ANS✔✔ Lift
equals weight and thrust equals drag
Which statement relates to Bernoulli's principle:
A. For every action there is an equal and opposite reaction
B. An additional upward force is generated as the lower surface of the airfoil deflects air downward
C. Air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface ANS✔✔ C is
correct
(Refer to Figure 1.) The acute angle A is the angle of
A. incidence
