Frequently asked

Are there any PIREPs near 5IS4?

18 pilot reports were filed within 100 NM of Corman Acres in the current reporting window, 6 of them reporting turbulence or icing.

What is a PIREP?

A pilot report is a first-hand account of conditions aloft filed by a pilot in flight: turbulence, icing, cloud bases and tops, flight visibility, wind and temperature. It is the only weather source that reports what an aircraft actually experienced rather than what a model or a ground sensor inferred. UA marks a routine report; UUA marks an urgent one.

How current are these reports?

The national PIREP feed carries roughly the last 90 minutes of reports and is republished every 5 minutes. A report is a snapshot of one aircraft at one place and time — conditions a few thousand feet away or twenty minutes later can differ.
