Buffalo Niagara International to Chicago/Rockford International BUF → RFD

460 nautical miles (530 statute miles) west on a straight line, true course 268°, about 279° magnetic at the departure end (variation 11W). At 120 knots that is 5 h 07 min at the quickest height in today's winds (4,500 ft, a 30-knot headwind), arriving about 11:24 am CDT (16:24 UTC). Right now BUF is VFR, wind from the south-southwest (200°) at 9 knots, gusting to 18; RFD is VFR, wind from the west-southwest (240°) at 7 knots. For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools. Airlines fly this pair: 8 flights in the DOT's last twelve reported months, the route's page.

The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words

Green, blue, red and purple airport dots are the flying conditions reported there now (VFR, marginal VFR, IFR, low IFR); grey means no report. Red areas are SIGMETs, orange areas AIRMETs, hatched red areas temporary flight restrictions. Map tiles: OpenFreeMap, data © OpenStreetMap contributors.

Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of

AIRMET ZULU 4C: moderate icing from 12,000 ft to 24,000 ft. Over the first 0 nm of the route.
AIRMET TANGO 1W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Near the route, 284 nm along the route.

Turbulence No turbulence warning in force along the route. AIRMET in force: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground), near the route, 284 nm along the route. 6 pilot reports of turbulence near the line in the last three hours: moderate turbulence above 34,000 ft, 36 nm northeast, 6:25 am EDT (10:25 UTC); moderate chop turbulence, at 8,000 ft, 25 nm south, 6:42 am EDT (10:42 UTC). The government's turbulence forecast map ↗

Icing AIRMET in force: moderate icing from 12,000 ft to 24,000 ft, over the first 0 nm of the route. A pilot reported no icing, at 23,000 ft, 0 nm southwest, 6:00 am EDT (10:00 UTC). The freezing level is about 13,500 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; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from BUF.

Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 UTC · at 120 knots true airspeed

The westbound cruising heights for this course (VFR: even thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 4 forecast points nearest it (BUF, CLE, MKG, JOT). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 13th at 06:00 UTC; valid on the 13th at 12:00 UTC for use 08:00 to 15:00 UTC; temperatures above 24,000 ft are below zero. Heights are above sea level; a height is left out when the forecast has no wind for it over most of the line (the ground is higher). Ground speed is the airspeed less the headwind; the time en route is for the straight line and ignores climb, descent and routing around weather.

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.

Daylight

Sunset at BUF 6:35 pm EDT (22:35 UTC), at RFD 6:18 pm CDT (23:18 UTC) (civil twilight ends 6:46 pm CDT (23:46 UTC)).

Each restriction opens the FAA's own page with the exact area, heights and times.
