  1. A remote pilot loses visual line of sight (VLOS) with the UAS unexpectedly. What is the correct immediate response?

    Answer: Activate RTH or have a visual observer reacquire the aircraft

    FAA Part 107 requires VLOS; activating RTH or using a visual observer to reacquire the aircraft restores compliance.

  2. During an emergency descent, which obstacle presents the greatest hidden hazard to a UAS pilot?

    Answer: Power lines and utility cables

    Power lines and utility cables are thin and extremely difficult to see, especially during rapid descents or in poor lighting.

  3. What action should a remote pilot take if a manned aircraft enters the flight area at low altitude?

    Answer: Descend the UAS and land as quickly as safely possible

    Manned aircraft always have right of way; descending and landing the UAS removes it from conflict airspace.

  4. A UAS enters an uncontrolled spin (toilet bowl effect) during flight. This is most commonly caused by:

    Answer: Compass interference or miscalibration

    The toilet bowl effect is typically caused by compass interference or a poorly calibrated compass affecting GPS-assisted flight modes.

  5. When should a remote pilot NOT use the Return-to-Home function as an emergency response?

    Answer: When the home point is in a hazardous location or obstacles are between the UAS and home

    RTH is unsafe if the home point is hazardous or obstacles exist along the return path, as the aircraft may not avoid them.

  6. What is the primary purpose of establishing a lost-link procedure before every UAS flight?

    Answer: To ensure the aircraft behaves predictably if communication is interrupted

    A pre-planned lost-link procedure ensures the UAS responds predictably — hover, RTH, or land — when the control link is severed.

  7. Which condition is most likely to cause a remote pilot to lose control link with the UAS?

    Answer: Radio frequency interference from nearby electronics or other transmitters

    RF interference from nearby electronic equipment, Wi-Fi networks, or other transmitters is the most common cause of control link loss.
