8.10 UAS Loading and Performance - Practice Questions

(Refer to FAA-CT-8080-2H, Figure 2, Load Factor Chart) At what bank angle does the load factor of your aircraft begin to change significantly?

• 15°

• 30°

• 45°

What happens when your UA center of gravity (CG) is too far aft, or too far to the back of, your aircraft?

• A longer take-off distance is required

• It's more difficult to recover from a stall / more difficult to control

• You'll see more maneuverability at higher altitudes

What is the rudder on a fixed-wing UA used for?

• Roll

• Pitch

• Yaw

To ensure that the unmanned aircraft center of gravity (CG) limits are not exceeded, follow the aircraft loading instructions specified in the

• Pilot's Operating Handbook or UAS Flight Manual.

• Aeronautical Information Manual (AIM).

• Aircraft Weight and Balance Handbook.

When operating an unmanned airplane, the remote pilot should consider that the load factor on the wings may be increased any time

• the CG is shifted rearward to the aft CG limit.

• the airplane is subjected to maneuvers other than straight-and-level flight.

• the gross weight is reduced.

A stall occurs when the smooth airflow over the unmanned airplane's wing is disrupted, and the lift degenerates rapidly. This is caused when the wing

• exceeds the maximum speed.

• exceeds maximum allowable operating weight.

• exceeds its critical angle of attack.

(Refer to FAA-CT-8080-2H, Figure 2, Load Factor Chart) If an unmanned airplane weighs 33 pounds, what approximate weight would the airplane structure be required to support during a 30° banked turn while maintaining altitude?

• 34 pounds

• 47 pounds

• 38 pounds

The four forces acting on an airplane in flight are

• weight, thrust, power, and drag.

• pitch, roll, yaw, and thrust.

• thrust, drag, weight (gravity), and lift.

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.

What is the relationship of lift, drag, thrust, and weight when the airplane is in straight-and-level flight?

• Lift equals weight and thrust equals drag.

• Lift, drag, and weight equal thrust.

• Lift and weight equal thrust and drag.
