What are PIREPs used for?
A Pilot Report or PIREP is a report of the actual weather conditions as encountered by an aircraft in flight. Traditionally, these reports are transmitted by radio to an appropriate ground station for dissemination but, when necessary, they can be made by telephone after landing.
Where can PIREPs be found?
Finding PIREPs:
- PIREPs are available through ATC, Flight Service Stations, or AviationWeather.gov.
- AviationWeather.gov PIREP Query.
What are two types of PIREPs?
There are two types of PIREPs: UA and UUA.
How often are PIREPs valid?
every 6 hours
According to the Aviation Weather Center, AIRMETs, (AIRman’s METeorological Information), “advises of weather that may be hazardous, other than convective activity, to single engine, other light aircraft, and Visual Flight Rule (VFR) pilots.” These are often considered widespread, affecting an area of at least 3000 …

AIRMETs are routinely issued for 6 hour periods beginning at 0245 UTC. AIRMETS are also amended as necessary due to changing weather conditions or issuance cancellation of a SIGMET.
What does Metar stand for?
Aviation Routine Weather Report
METAR is the international standard code format for hourly surface weather observations which is analogous to the SA coding currently used in the US. The acronym roughly translates from French as Aviation Routine Weather Report.
WHO issues SIGMETs?

Urgent PIREPs describe weather phenomena that are potentially hazardous to flight operations, including: Tornadoes, funnel clouds, or waterspouts. Severe or extreme turbulence. Severe icing.
Can you fly in an AIRMET?
Although you can usually legally fly through a convective SIGMET, why would you risk it? Think carefully about flying in AIRMETs. These weather conditions can still be dangerous, but you can avoid the risk by adjusting your flight plan or taking the necessary precautions.
Can you fly in SIGMET?
Great question, and the short answer is yes, you absolutely can legally fly through a convective SIGMET… unless your specific operating/military regulations prohibit it.
When do pilots need to report turbulence to ATC?
PIREPs Relating to Turbulence: When encountering turbulence, pilots are urgently requested to report such conditions to ATC as soon as practicable PIREPs relating to turbulence should state: Aircraft location Example: Over Omaha, 1232Z, moderate turbulence in clouds at Flight Level three one zero, Boeing 707
How does an air traffic controller submit a PIREP?
The submission of a PIREP can be initiated by both the pilot or an air traffic controller One of the primary duties of the Inflight position is to serve as a collection point for the exchange of PIREPs with en route aircraft
What does severe turbulence mean in a PIREP?
Severe or extreme turbulence (including clear air turbulence) Low-Level Windshear (LLWS) which is defined as fluctuations of more than 10 kts of airspeed Any other weather which the weather specialist may deem hazardous or potentially hazardous to flying. As you can see, Urgent PIREPs are serious.
