Emergency Procedures, Maintenance & Inspection

Correct

The answer is C: Log it in the maintenance record and report the anomaly

After GPS jamming or spoofing, the AIM recommends documenting it in the maintenance log so that faults are cleared, and filing a report through the FAA's GPS anomaly reporting site. A GPS anomaly that ends in a normal landing isn't an NTSB notification, and a safe landing doesn't remove the value of the record.

Correct

The answer is B: Whether other pilots could see it 3 SM away here

AC 107-2A's night risk questions ask whether you, and other aircraft operating in the area, will be able to see the anti-collision light for at least 3 SM, considering weather such as fog and terrain such as hills and mountains, and whether the flash rate is sufficient. The light is there for other pilots, so seeing it yourself isn't enough, and it may be dimmed for safety but not switched off.

Correct

The answer is B: Find the source; it may be a fire or extreme-heat hazard

Table C-1 lists a smell of electrical burning or arcing, and visible signs such as soot tracings or sparking, as conditions calling for further inspection to find the possible electrical malfunction, which may pose a risk of fire or extreme heat. A test hover, or waiting for visible smoke, skips the inspection.

Correct

The answer is B: As unscheduled maintenance to finish before flying

AC 107-2A defines small UAS maintenance to include system software upgrades, and says a manufacturer may require an unscheduled software update to correct a problem; when such a condition is found, flight operations should not occur until it is corrected. It isn't deferred to the scheduled interval just because it comes from the manufacturer.

Correct

The answer is C: Cover the whole system, scaled to the aircraft and job

AC 107-2A says the preflight inspection should be scalable to the small UAS, the program and the operation, and should encompass the entire system (aircraft, control station, links, power, support equipment) to determine a continued condition for safe operation before each flight. Two items aren't the whole system, and a monthly full check doesn't meet the before-each-flight standard.
