Key Takeaways:

  • Filing pilot weather reports (PIREPs) in flight is cumbersome, leading to a scarcity of low-altitude weather data.
  • The former reliable service for filing PIREPs, Enroute Flight Advisory Service (EFAS) or Flight Watch (122.0 MHz), was terminated on October 1, 2015.
  • Pilots must now file PIREPs by contacting a Flight Service Station (FSS), which requires locating the correct FSS frequency and name using resources like VFR sectionals or electronic flight bags.
  • Filing with an FSS can involve specific communication procedures, such as transmitting on one frequency and listening for a response over an associated VOR frequency.

Question: How do I file a pilot weather report online?

Answer: In general aviation, one of the most cumbersome things to do while in flight is to file a pilot weather report, more commonly known as a PIREP. This has created the unfortunate situation that on any given day 98 percent of the PIREPs in the system are typically describing weather conditions at or above 18,000 feet.
