A remote pilot must abort a flight when the UAS enters a fail-safe return-to-home (RTH) sequence. The FIRST action should be:
Answer: Cancel RTH and regain manual control if safe to do so
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.
What effect does a strong crosswind have on a multirotor UAS's battery consumption?
Answer: It increases consumption as motors work harder to maintain position
In a crosswind, the flight controller commands motor speed changes to counteract wind drift, increasing power draw and reducing overall flight time.
During an emergency, a sUAS propeller separates mid-flight. The CORRECT immediate action is to:
Answer: Cut throttle and attempt to land immediately in the safest available area
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.
The maximum endurance airspeed for a fixed-wing UAS is BEST described as the speed that:
Answer: Minimizes total power required to maintain level flight
Maximum endurance is achieved at the speed of minimum power required, which allows the aircraft to stay airborne the longest on available battery energy.
A remote pilot is operating a UAS on a hot summer day and notices sluggish motor response. The MOST likely cause is:
Answer: Motor windings overheating, causing thermal protection throttle reduction
Excessive heat causes motor winding resistance to increase and activates thermal protection circuits, reducing available power and making the aircraft respond sluggishly.
When planning a flight in a confined area with obstacles, which loading consideration is MOST critical?
Answer: Keeping the CG within limits to maintain maneuverability for obstacle avoidance
A CG within manufacturer limits ensures predictable and responsive handling needed to safely navigate around obstacles in confined spaces.
Which emergency procedure is correct when a sUAS experiences a fly-away due to compass interference?
Answer: Switch off GPS, take manual control, and land as soon as possible
Compass interference corrupts GPS-based navigation; switching to manual/attitude mode removes the erroneous GPS input, giving the pilot direct control to execute an emergency landing.
