  1. A Terminal Aerodrome Forecast (TAF) covers what time period?

    Answer: 24 to 30 hours

    TAFs are issued four times daily and cover a 24-hour forecast period (sometimes 30 hours for major airports) in a 5-statute-mile radius of the airport.

  2. What METAR sky condition code indicates a broken cloud layer?

    Answer: BKN

    BKN (broken) indicates 5 to 7 oktas (5/8 to 7/8) of sky coverage and constitutes a ceiling when the layer is below 5,000 ft AGL.

  3. What does the 'TEMPO' group in a TAF indicate?

    Answer: Temporary fluctuations lasting less than one hour and less than half the period

    TEMPO in a TAF describes temporary fluctuations in weather conditions that last less than one hour at a time and less than half of the indicated time period.

  4. What is the primary hazard associated with freezing rain (FZRA) for arriving and departing aircraft?

    Answer: Rapid, hard-to-remove ice accumulation on lifting surfaces

    Freezing rain creates clear ice that accumulates rapidly on airframe surfaces, is aerodynamically disruptive, and is extremely difficult to remove with standard de-icing equipment.

  5. A pilot requests 'ride reports' from ATC. What is the controller's proper action?

    Answer: Relay available PIREPs and solicit new reports from other aircraft in the area

    Controllers should relay any available PIREPs (Pilot Reports) and, when able, solicit turbulence ride reports from other aircraft operating in the area.

  6. Which cloud type is most associated with severe turbulence, hail, and lightning that controllers must relay to pilots?

    Answer: Cumulonimbus

    Cumulonimbus (CB) clouds are the mature stage of thunderstorm development and contain all severe weather hazards including turbulence, hail, lightning, and icing.
