Drone Operations & Safety Procedures Flashcards

Under Part 107, what is the maximum groundspeed allowed for a small UAS during flight?

Answer: 87 knots

Part 107.51 limits small UAS groundspeed to 87 knots (100 mph).

A remote PIC loses visual contact with their drone during an authorized BVLOS operation. What is the correct first action?

Answer: Activate the return-to-home function immediately

Activating return-to-home restores the aircraft to a known location and helps reestablish visual contact safely.

When operating near a wildfire suppression operation, a temporary flight restriction (TFR) is typically issued. What minimum distance must an unwaivered drone operator maintain?

Answer: 1 nautical mile

FAA TFRs for wildfire suppression typically establish a 1 NM radius and specific altitude restrictions to protect firefighting aircraft.

Which of the following actions is required before each flight under Part 107?

Answer: Inspect the sUAS to ensure it is in safe operating condition

Part 107.49 requires the remote PIC to inspect the sUAS and ensure it is in safe operating condition before each flight.

A remote PIC is operating in Class G airspace at 300 feet AGL. A manned helicopter approaches at 400 feet AGL. What does right-of-way require?

Answer: The drone must give way to the manned aircraft

Part 107.37 requires that small unmanned aircraft always yield right-of-way to all manned aircraft.

What does the term 'visual line of sight' (VLOS) require under Part 107?

Answer: Unaided vision or corrective lenses only — binoculars are not permitted

Part 107 VLOS requires unaided or correctively-lensed vision; binoculars or other magnifying devices do not satisfy the requirement.

During a sUAS preflight inspection, the remote PIC notices a small crack in one of the propeller blades. What is the correct action?

Answer: Replace the propeller before flight

A cracked propeller must be replaced before flight because propeller failure can cause loss of control and create a safety hazard.
