UAS Flight Operations 2 — Questions and Answers
Question 1: Under 14 CFR Part 107, what is the maximum groundspeed allowed for a small UAS?
- 87 knots (100 mph) (Correct answer)
- 100 knots (115 mph)
- 107 knots (123 mph)
- 120 knots (138 mph)
Correct answer: 87 knots (100 mph)
Part 107 limits small UAS groundspeed to no more than 87 knots (100 mph) during flight.
Question 2: When operating a sUAS at night under Part 107, which lighting requirement must be met?
- Anti-collision light visible for at least 3 statute miles (Correct answer)
- Strobe light visible for 1 statute mile
- Red and green position lights only
- No lighting is required if flying below 100 feet AGL
Correct answer: Anti-collision light visible for at least 3 statute miles
Part 107 requires an anti-collision light visible for at least 3 statute miles when operating at night.
Question 3: A remote PIC is planning to fly a sUAS near a wildfire. Which agency must grant authorization?
- FAA via LAANC or DroneZone waiver
- National Interagency Fire Center (NIFC)
- Local fire incident commander (Correct answer)
- State aviation authority
Correct answer: Local fire incident commander
The FAA issues Temporary Flight Restrictions (TFRs) over wildfires, but flight within the TFR requires coordination with and authorization from the incident commander on scene.
Question 4: What does a METAR code 'OVC010' indicate?
- Overcast ceiling at 1,000 feet AGL (Correct answer)
- Overcast visibility of 10 statute miles
- Scattered clouds at 10,000 feet MSL
- Broken ceiling at 1,000 feet MSL
Correct answer: Overcast ceiling at 1,000 feet AGL
OVC indicates overcast sky coverage and the number '010' represents the ceiling height in hundreds of feet AGL, equaling 1,000 feet.
Question 5: During preflight, a remote PIC notices a small crack in the sUAS airframe. What is the correct action?
- Do not fly until the aircraft is repaired and deemed airworthy (Correct answer)
- Fly at reduced altitude and speed to minimize stress on the airframe
- Note the defect in a logbook and proceed with caution
- Fly only if the crack does not affect propeller or motor mounts
Correct answer: Do not fly until the aircraft is repaired and deemed airworthy
The remote PIC is responsible for ensuring the sUAS is in safe operating condition before each flight; any structural damage makes it unairworthy.
Question 6: What is the purpose of a Lost Link (RTH) procedure during sUAS operations?
- To automatically return the aircraft to its home point when the control link is severed (Correct answer)
- To notify ATC when radio communication is lost
- To shut down motors immediately upon signal loss
- To activate an emergency locator transmitter
Correct answer: To automatically return the aircraft to its home point when the control link is severed
Return-to-Home (RTH) is a contingency procedure that autonomously flies the aircraft back to its launch point when the control link is lost.
Question 7: Under what condition may a remote PIC deviate from Part 107 regulations without a waiver?
- In response to an in-flight emergency to ensure safety (Correct answer)
- When flying for recreational purposes only
- If the operation is conducted below 50 feet AGL
- When visual observers are present at all times
Correct answer: In response to an in-flight emergency to ensure safety
Part 107.21 permits deviation from any rule to the extent necessary to meet an emergency that requires immediate action.
