FAA Private Pilot Helicopter (PRH)WeatherMedium

A pilot preparing for a flight through mountainous terrain wants current, actual weather conditions reported by other pilots who recently flew the route. Which report should be requested from Flight Service?

  1. AMETAR
  2. BPIREP
  3. CAIRMET
  4. DTAF
Show answer & explanation

Correct answer: B. PIREP

A Pilot Report (PIREP) provides firsthand, in-flight observations of actual conditions such as turbulence, icing, cloud tops, and visibility, making it the best source for current conditions along a specific route as experienced by other pilots.

Why the other options are wrong

  • A. A METAR is a scheduled surface observation at an airport, not an en route pilot report.
  • C. An AIRMET is a forecast advisory for hazardous weather, not an actual pilot-reported condition.
  • D. A TAF is a scheduled forecast for a specific airport, not an actual in-flight pilot observation.

Pilot Report (PIREP)

A report of actual in-flight weather conditions, such as turbulence, icing, cloud tops/bases, and visibility, submitted by pilots to help other pilots and forecasters.

  • Provides real-time, actual conditions rather than forecasts
  • Coded format includes location, time, altitude, aircraft type, and conditions
  • Especially valuable in mountainous or data-sparse areas

Memory trick: PIREP = Pilots Reporting Exactly what's Present
