METEOROLOGY FLIGHT PLANNING
In-flight when requested
When unusual or unforecast weather conditions are encountered
When weather conditions on an IFR approach differ from the latest observation
When a missed approach is executed due to weather
When a wind shear is encountered on departure or arrival
Your observed PIREPs should be given to any ground facility with which you have established
communication (e.g., FSS, ARTCC, EFAS-En route Flight Advisory Service, etc.). After passing
the immediately pertinent information, you should follow up with a radio call to a Meteorology
Office (METRO) to ensure rapid dissemination to other using agencies. If you are not able to
report while in the air, you should make a report to the nearest FSS or Weather Service Office
upon landing, especially if weather encountered was different than forecast.
When airborne, you would consult the Flight Information Handbook for the proper format, which
includes aircraft identification, location, time (UTC), altitude (MSL), type aircraft, sky cover,
visibility and weather, temperature, wind, turbulence, icing, and remarks. Even though your pilot
report should be as complete and accurate as possible, do not be overly concerned with strict
format and phraseology. The important thing is that your PIREP is relayed so others may benefit
from your report (Figure 3-8).
