WEEK 3 QUIZ

What is the purpose of the rudder on an airplane?

• To control yaw.

• To control over banking tendency.

• To control roll.

An airplane said to be inherently stable will

• Be difficult to stall.

• Require less effort to control.

• Not spin.

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 the rudder trim tab.

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

Loading an airplane to the most aft CG will cause the airplane to be.

• Less stable at all speeds.

• Less stable at slow speeds, but more stable at high speeds.

• Less stable at high speeds, but more stable at low speeds.

If an airplane weighs 2,300 pounds, what approximate weight would the aircraft structure be required to support during a 60 degree banked turn while maintaining altitude?

• 2,300 Pounds

• 3,400 Pounds

• 4,600 Pounds

The amount of excess load that can be imposed on the wing of an airplane depends upon the

• Position of the CG.

• Speed of the airplane.

• Abruptness at which the load is applied.

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

• Climbs

• Turns

• Stalls

During a spin to the left, which wing(s) is/are stalled?

• Both wings are stalled

• Neither wing is stalled

• Only the left wing is stalled

Wingtip vortices are created only when an aircraft is

• Operating at high airspeeds.

• Heavily loaded.

• Developing lift.

The greatest vortex strength occurs when the generating aircraft is

• Light, dirty, and fast.

• Heavy, dirty, and fast.

• Heavy, clean and slow
