Aerodynamics Unit Exam - FAA Questions

What is the purpose of the rudder on an airplane?

• To control yaw.
• To control roll.
• To control overbanking tendency.

In straight-and-level flight, if thrust exceeds drag then:

• There is no direct correlation between thrust and drag.
• Speed decreases.
• Speed increases.

When are the four forces that act on an airplane in equilibrium?

• During unaccelerated flight.
• When the aircraft is accelerating.
• When the aircraft is at rest on the ground.

In slow flight, prior to a stalled condition:

• The noise of the propeller increases.
• The controls start to feel mushy—not as responsive.
• The nose of the airplane begins to bounce around the horizon.

Extending the flaps:

• Lowers the stalling speed.
• Increases the stalling speed.
• Allows for more stable control in a slow flight condition.

A turn coordinator provides an indication of the:

• attitude of the aircraft with reference to the longitudinal axis.
• angle of bank up to but not exceeding 30°.
• movement of the aircraft about the yaw and roll axis.

Using a turn and slip indicator, how do you know that you are in a coordinated turn?

• The miniature airplane’s wing is pointing to the 15 degree mark
• The miniature airplane’s wing is pointing to the 30 degree mark.
• Centering the ball results in a coordinated turn.

Which basic flight maneuver increases the load factor on an airplane as compared to straight-and-level flight?

• Climbs.
• Stalls.
• Turns.

What force makes an airplane turn?

• The vertical component of lift.
• Centrifugal force.
• The horizontal component of lift.

What are the three axes of rotation for an airplane?

• Vertical, longitudinal, and aileron.
• Lateral, rudder, and aileron.
• Lateral, vertical, and longitudinal.
