Lesson 26 Flashcards
What is the purpose of a PIREP?
to report meteorological conditions in flight
Name the 2 classifications of PIREPs:
- Urgent (UUA): weather phenomena reported by a pilot which represent a hazard or a potential hazard to flight operations
- Routine (UA): all received PIREPs are classified as routine
______ use PIREPs to expedite traffic flow in the vicinity of the airport and to provide hazardous weather avoidance procedures.
Towers and TRACONs
_______ use PIREPs to brief pilots and issue in flight advisories, and weather avoidance information to en route aircraft
Automated Flight Service Stations (AFSSs)
______ uses the reports to expedite the flow of en route traffic, to determine most favorable altitudes, and to issue hazardous weather information within the center’s area.
the ARTCC
______ uses the reports to expedite the flow of en route traffic, to determine most favorable altitudes, and to issue hazardous weather information within the center’s area.

The National Weather Service (NWS) uses PIREPs to:
- verify or amend conditions contained in forecasts and advisories
- triggering mechanism for issuing advisories
- pilot weather breifings
- study meteorological phenomena
ATC facilities are required to solicit PIREPs from aircraft when one of the following conditions EXIST or are FORECAST:
- ceilings at or below 5,000 ft
- visibility 5 miles or less
- thunderstorms and related phenomena
- turbulence
- icing
- wind shear
- volcanic ash clouds are reported or forecast
- when braking action advisories are in effect (terminal only)
Ensure each PIREP includes:
- location
- time
- altitude/ flight level
- type aircraft
- at least one other element
Ensure each PIREP includes:
- location
- time
- altitude/ flight level
- type aircraft
- at least one other element
When a PIREP includes turbulence, include:
- whether in clouds or clear air
- type and intensity of turbulence
When the PIREP involves icing, include:
- type and intensity of icing
- air temperature in which icing is occurring
/OV
location in reference to a VHF NAVAID or an airport
/TM
Time phenomenon occurred or was encountered
/FL
altitude where phenomenon occurred
