  1. A remote pilot plans a flight 3 nautical miles from launch. If the GPS fails mid-flight, which action best supports navigation back to launch?

    Answer: Use pre-noted compass heading and elapsed time for dead reckoning return

    Recording the outbound heading and time allows the pilot to reverse course and use elapsed time to estimate distance back to the launch point.

  2. On a sectional chart, what does a 'R' followed by a number (e.g., R-2508) designate?

    Answer: A restricted area

    The prefix 'R-' on a sectional chart identifies restricted airspace, which has limitations on non-participating aircraft without ATC authorization.

  3. Which of the following best describes 'track' in UAS navigation terminology?

    Answer: The actual path of the aircraft over the ground

    Track (also called course made good) is the actual path the aircraft travels over the ground, which may differ from heading due to wind.

  4. A remote pilot in the US notices their sectional chart was revised 6 months ago. Why might this be a concern?

    Answer: New temporary flight restrictions, airspace changes, or new obstacles may not be depicted

    Sectional charts in the US are updated every 56 days; a 6-month-old chart may not reflect new TFRs, airspace reclassifications, or newly erected obstacles.

  5. When a sUAS pilot calculates their maximum operating radius from launch, which factor primarily limits the legal distance for Part 107 operations?

    Answer: Visual line-of-sight limitation

    Part 107 requires the remote pilot or a visual observer to maintain unaided visual line of sight with the sUAS at all times.

  6. What does the phrase 'course reversal' refer to in UAS navigation planning?

    Answer: Flying the reciprocal (opposite) heading to return to origin

    A course reversal means flying the reciprocal heading—exactly 180° opposite to the outbound heading—to return directly to the starting point.

  7. A pilot observes that a tower symbol on the sectional chart shows '1547' and '(849)'. What do these numbers represent?

    Answer: MSL elevation (1547 ft) and AGL height (849 ft) of the tower top

    On sectional charts, the upper bold number is the obstruction's top elevation MSL, and the lower parenthetical number is its height above ground level.
