Chicago/Rockford International to Boise Air Trml/Gowen Field RFD → BOI

1,191 nautical miles (1,371 statute miles) west on a straight line, true course 283°, about 286° magnetic at the departure end (variation 3W). At 120 knots that is 10 h 38 min at the quickest height in today's winds (4,500 ft, a 8-knot headwind), arriving about 2:34 pm MDT (20:34 UTC). Right now RFD is VFR, wind from the southwest (220°) at 11 knots; BOI is VFR, wind from the west-northwest (290°) at 9 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: 1 flights in the DOT's last twelve reported months, the route's page.

Icing AIRMET in force: moderate icing up to 22,000 ft, over the route from 576 to 1032 nm out. No pilot has reported icing near the line in the last three hours. The freezing level is about 11,500 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 RFD.

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 9 forecast points nearest it (DBQ, MCW, FSD, ONL, PIR, RAP, LND, PIH, BOI). 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 RFD 6:18 pm CDT (23:18 UTC), at BOI 7:03 pm MDT (01:03 UTC) (civil twilight ends 7:32 pm MDT (01:32 UTC)).

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

The wind over the route live wind map, from Windy.com · drag the time bar for the coming hours; the level menu changes the height

Colours show wind speed, the moving lines its direction, at the surface unless you pick a height. Map and forecast by Windy.com; a second opinion beside the government's winds-aloft table above.
