410. PILOT WEATHER REPORTS (PIREP)
FAA air traffic facilities are required to solicit PIREPs whenever ceilings are at or below
5000 feet, visibility is at or below five miles (surface or aloft), thunderstorms and related
phenomena, icing of light degree or greater, turbulence of moderate degree or greater, wind shear
or volcanic ash clouds are reported or forecast. Aircrews are urged to cooperate and volunteer
reports of cloud tops, upper cloud layers, thunderstorms, ice, turbulence, strong winds and other
significant flight condition information. The PIREP should be transmitted to METRO, if
possible, or to the FAA ground facility with which communication is established (e.g., FSS or
ARTCC). The format and procedures are contained in Section C of the Flight Information
"KATT 833, Eglin Metro, request PIREP."
"KATT 833, 20 miles east of Crestview at 10,000,
T-34, cloud Tops 15,000, temperature + 20, wind
280/10, light turbulence in clouds."
"KATT 833, roger."
Section C of the Flight Information Handbook (see Figure 4-7) contains airframe icing and
turbulence reporting criteria tables. These tables give specific descriptions of intensities of icing
and turbulence. The most important information for any PIREP would be your type of aircraft
and position/altitude. There is a tremendous difference between a T-34 reporting moderate
turbulence and a 747 reporting moderate turbulence.
