  1. What information should a remote pilot record in a maintenance log after replacing a motor on a sUAS?

    Answer: Date, nature of maintenance, parts used, and who performed the work

    A thorough maintenance record includes the date, description of work, replacement parts, and the person who performed the work to establish a complete maintenance history.

  2. A pilot notices that the flight controller firmware update available is marked 'mandatory safety update.' What action should be taken?

    Answer: Apply the update before the next flight and verify all systems after updating

    Mandatory safety updates address known safety-critical bugs or vulnerabilities and must be applied before operating the aircraft to maintain airworthiness.

  3. Which of the following best describes 'range testing' as part of a sUAS pre-flight check?

    Answer: Verifying control link integrity at a reduced power setting according to manufacturer procedures

    Range testing uses a reduced transmitter power mode to simulate long-range signal conditions at close range, allowing verification of control link quality without actually flying far away.

  4. A remote pilot discovers that the propeller mounting nuts were over-tightened during the last maintenance session, causing thread damage. What is the appropriate response?

    Answer: Replace the damaged hardware with manufacturer-approved fasteners before flying

    Damaged threads cannot reliably secure propellers under flight loads and vibration, so stripped or damaged fasteners must be replaced with approved hardware before flight.

  5. What is the significance of checking the center of gravity (CG) on a sUAS before flight?

    Answer: An improperly balanced CG can cause unpredictable flight characteristics and reduce motor authority

    An off-center CG forces some motors to work harder to maintain level flight, reduces maneuverability, and can cause the aircraft to flip if one motor reaches its limit.

  6. Under Part 107, who is responsible for ensuring a sUAS is in a condition for safe operation before each flight?

    Answer: The remote pilot in command

    Part 107.15 places the responsibility for ensuring the sUAS is in safe operating condition directly on the remote pilot in command before each flight.

  7. A remote pilot is about to fly in cold weather (below 32°F / 0°C). Which battery-related precaution is most important?

    Answer: Pre-warm the batteries and expect reduced capacity and flight time

    LiPo batteries suffer significant capacity reduction in cold temperatures, and flying without pre-warming them can cause sudden voltage drop and unexpected power loss mid-flight.
