Aviation Quiz

What is the purpose of the rudder on an airplane?

• To control yaw.

• To control overbanking tendency.

• To control roll.

Trim systems are designed to do what?

• They relieve the pilot of the need to maintain constant back pressure on the flight controls.

• They are used during approach and landing to increase wing lift.

• They move in the opposite direction from one another to control roll.

The term "angle of attack" is defined as the angle

• between the wing chord line and the relative wind.

• between the airplane's climb angle and the horizon.

• formed by the longitudinal axis of the airplane.

Ground effect is most likely to result in which problem?

• Settling to the surface abruptly during landing.

• Becoming airborne before reaching recommended takeoff speed.

• Inability to get airborne even though airspeed is sufficient for normal takeoff needs.

In what flight condition must an aircraft be placed in order to spin?

• Partially stalled with one wing low.

• In a steep diving spiral.

• Stalled.

What determines the longitudinal stability of an airplane?

• The location of the CG with respect to the center of lift.

• The effectiveness of the horizontal stabilizer, rudder, and rudder trim tab.

• The relationship of thrust and lift to weight and drag.

As altitude increases, the indicated airspeed at which a given airplane stalls in a particular configuration will

• decrease as true airspeed decreases.

• decrease as the true airspeed increases.

• remain the same regardless of altitude.

Which statement is true concerning primary flight controls?

• The effectiveness of each control surface increases with speed because there is more flow over them.

• Only when all three primary flight controls move in sequence do the airflow and pressure distribution change over and around the airfoil.

• Primary flight controls include ailerons, rudder, elevator, and trim systems.

In what flight condition are torque effects more pronounced in a single-engine airplane?

• Low airspeed, high power, high angle of attack.

• Low airspeed, low power, low angle of attack.

• High airspeed, high power, high angle of attack.

Floating caused by the phenomenon of ground effect will be most realized during an approach to land when at

• less than the length of the wingspan above the surface.

• twice the length of the wingspan above the surface.

• a higher-than-normal angle of attack.
