  1. What information does a Terminal Aerodrome Forecast (TAF) provide that is most useful for drone pilots?

    Answer: Forecast weather conditions at an airport for up to 30 hours

    A TAF provides forecast weather conditions including wind, visibility, and sky cover at an airport location for up to 30 hours ahead.

  2. Which condition is most dangerous for drone operations involving potential ice accumulation?

    Answer: Flying through visible moisture when temperatures are near or below freezing

    Flying through visible moisture such as clouds, rain, or fog when temperatures are near or below freezing creates structural icing risk on drone components.

  3. What does 'wind shear' mean in the context of drone flight planning?

    Answer: A sudden change in wind speed or direction over a short distance

    Wind shear is a sudden change in wind speed or direction over a short distance, which can cause rapid and unexpected changes in drone performance.

  4. Under Part 107, which weather condition would most likely require a waiver before conducting operations?

    Answer: Flight visibility below 3 statute miles

    Part 107 requires minimum 3 statute miles flight visibility; operations below this visibility require a waiver from the FAA.

  5. What is a 'convective SIGMET' and when would a drone pilot likely encounter its effects?

    Answer: A warning about severe thunderstorm-related hazards including turbulence and hail

    A convective SIGMET warns of severe thunderstorm-related hazards such as extreme turbulence, hail, and lightning that pose serious risk to all aircraft including drones.

  6. How does a temperature inversion affect low-altitude drone flights?

    Answer: Can trap pollutants and reduce visibility; also creates unusual wind patterns

    A temperature inversion can trap pollutants, haze, and fog below the inversion layer reducing visibility, and creates unusual wind shear at the inversion boundary.

  7. When reading a METAR, what does 'OVC008' in the sky condition field indicate?

    Answer: Overcast clouds at 800 feet AGL

    OVC008 means overcast cloud layer at 800 feet AGL (cloud heights in METARs are reported in hundreds of feet).
