UNDERSTANDING PIREPS
The following is an example of a typical PIREP with an explanation of the
elements.
1. Station Identifier: KCRW
This is the station identifier of the nearest weather reporting location to
the reported conditions.
2. Report Type: UA
Reports will be routine (UA) or urgent (UUA).
3. Location: OV KBKW 360015-KCRW
OV indicates the report is in relation to a VOR. KBKW is the VOR iden-
tifier, in this case Beckley VOR. 360015-KCRW indicates position as
related to the VOR. In this case, 15 miles out on the 360 degree radial.
KCRW indicates this is a leg to the Charleston, West Virginia VOR.
The next series of elements contain data that is read much like that in
METARs and TAFs. Each element starts with a 2-letter designator which
denotes the type of data with that element. The following defines the ele-
ment designators:
/TM: Time as Coordinated Universal Time
/FL: Altitude as Flight Level
/TP: Aircraft Type
/SK: Sky Cover (may include cloud height and coverage)
/WX: Weather Phenomenon (can include flight visibility, precipitation
and restrictions to visibility.
/TA: Outside air temperature at altitude in degrees Celsius.
/WV: Wind (direction in degrees magnetic north and speed in knots)
/TB: Turbulence (refer to the Airman’s Information Manual)
CAT - Clear Air Turbulence
CHOP - Choppy Turbulence
OCNL - Occasional
NEG - No Turbulence
ABV - Above
BLO - Below
