Chapter 4 - Loading & Performance

Question 1

True/False - A UAS may carry a payload of hazardous materials as defined by 49 CFR 171?

Answer 1

False, UAS may not transport hazardous materials without a waiver

Question 2

As density altitude increases, what happens to the performance of the UAS?

Answer 2

Decreases

Question 3

What causes density altitude to increase?

Answer 3

High altitude, high temperature, high humidity

Question 4

What is the critical angle of attack?

Answer 4

The angle at which lift is no longer generated and the UAS goes into an aerodynamic stall.

Question 5

According to 14 CFR part 107, who is responsible for determining the performance of a small unmanned aircraft?

1. Owner or operator
2. Remote Pilot in Command
3. Manufacturer

Answer 5

Remote Pilot in Command

Question 6

When operating an unmanned aircraft, the Remote Pilot in Command should consider that the load factor on the wings or rotors may be increased anytime when:

1. The center of gravity (CG) is shifted rearward to the aft CG limit
2. The aircraft is subjected to maneuvers other than straight and level flight.
3. The gross weight is reduced

Answer 6

The aircraft is subjected to maneuvers other than straight and level flight.

Question 7

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:

1. Exceeds maximum allowable operating weight
2. Exceeds the maximum speed
3. Exceeds its critical angle of attack

Answer 7

Exceeds its critical angle of attack

Question 8

Before each flight, the Remote PIC must ensure that:

1. The site supervisor has approved the flight
2. Objects carried on the sUAS are secure
3. ATC has granted clearance

Answer 8

Objects carried on the sUAS are secure

Question 9

What could be a consequence of operating a small unmanned aircraft above its maximum allowable weight?

1. Increased maneuverability
2. Shorter endurance
3. Faster speed

Answer 9

Shorter endurance

Question 10

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

1. Aircraft Weight and Balance Handbook
2. Pilot’s Operating Handbook or UAS Flight Manual
3. Aeronautical Information Manual (AIM)

Answer 10

Pilot’s Operating Handbook or UAS Flight Manual
