Flight planning: Illinois Valley Rgnl-Walter A Duncan Field VYS / KVYS

What a pilot looks at before a flight from or to Illinois Valley Rgnl-Walter A Duncan Field in Peru, Illinois, in plain English: right now VFR: good flying weather, Wind from the south (170°) at 4 knots. The warnings, reports and winds below come from the government's aviation weather service and the restrictions from the FAA, refreshed every few minutes. For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools.

Warnings in force SIGMETs and AIRMETs whose area covers this field

No SIGMET or AIRMET covers this field right now.

Turbulence No turbulence warning in force over this field. No pilot has reported turbulence within 100 nautical miles in the last three hours. The government's turbulence forecast map ↗

Icing No icing warning in force over this field. No pilot has reported icing within 100 nautical miles in the last three hours. The freezing level is about 12,000 ft (from the winds-aloft temperatures), so icing is possible in cloud above that. The government's icing forecast map ↗

A SIGMET warns of weather hazardous to all aircraft (thunderstorms, severe turbulence or icing, volcanic ash); an AIRMET of weather that matters to small aircraft and to flying without instruments (moderate turbulence or icing, low cloud, strong surface wind, mountains hidden in cloud). An area is counted when it covers this field's position.

Pilot reports within 100 nautical miles, last three hours, nearest first

Not fetched just now.

What pilots in the air told air traffic control or Flight Service: turbulence, icing, cloud tops and bases, temperature, wind, and whatever they remarked on (wind shear on final, a smooth ride). An urgent report is one of severe turbulence or icing, wind shear, or similar. Open "as filed, and in English" for the coded report and its translation line by line.

Winds and temperatures aloft forecast point JOT, 45 nm east of the field · for use 02:00–09:00 UTC

Height	Wind from	Speed	Temperature

Based on data from the 27th at 00:00 UTC; valid on the 27th at 06:00 UTC for use 02:00 to 09:00 UTC; temperatures above 24,000 ft are below zero. Heights are above sea level; the lowest rows are left out where the ground is already that high.

Temporary flight restrictions within 50 nautical miles, from the FAA's list

No temporary flight restriction within 50 nautical miles right now.

From the FAA's notice service (NOTAMs), the site's copy refreshed every few minutes; last checked a minute ago. The FAA has so far issued eFlight its test feed, which misses some notices (checked against the FAA's own search on 12 October: about a third missing at Santa Barbara and Burbank, none at Atlanta or Las Vegas); the request for the full feed is with the FAA. Times are local to the field. This is for planning; the legal briefing comes from Flight Service or the FAA's own tools.
