RPC UAS Loading, Performance & Emergency Procedures 3

Question 1

A remote pilot must abort a flight when the UAS enters a fail-safe return-to-home (RTH) sequence. The FIRST action should be:

Accepted Answer

Cancel RTH and regain manual control if safe to do so

Answer

The pilot should attempt to cancel RTH and resume manual control first, because RTH may navigate the UAS into obstacles if the home point or environment has changed.

Question 2

What effect does a strong crosswind have on a multirotor UAS's battery consumption?

Accepted Answer

It increases consumption as motors work harder to maintain position

Answer

In a crosswind, the flight controller commands motor speed changes to counteract wind drift, increasing power draw and reducing overall flight time.

Question 3

During an emergency, a sUAS propeller separates mid-flight. The CORRECT immediate action is to:

Accepted Answer

Cut throttle and attempt to land immediately in the safest available area

Answer

A separated propeller makes controlled flight impossible or highly unstable; the pilot must immediately reduce throttle and guide the aircraft to the safest available landing area.

Question 4

The maximum endurance airspeed for a fixed-wing UAS is BEST described as the speed that:

Accepted Answer

Minimizes total power required to maintain level flight

Answer

Maximum endurance is achieved at the speed of minimum power required, which allows the aircraft to stay airborne the longest on available battery energy.

Question 5

A remote pilot is operating a UAS on a hot summer day and notices sluggish motor response. The MOST likely cause is:

Accepted Answer

Motor windings overheating, causing thermal protection throttle reduction

Answer

Excessive heat causes motor winding resistance to increase and activates thermal protection circuits, reducing available power and making the aircraft respond sluggishly.
