Central IL Rgnl/Bloomington-Normal Airport to University Of Illinois/Willard Airport BMI → CMI
39 nautical miles (45 statute miles) southeast on a straight line, true course 132°, about 135° magnetic at the departure end (variation 3W). At 120 knots that is 15 min at the quickest height in today's winds (24,000 ft, a 34-knot tailwind), arriving about 10:18 am CDT (15:18 UTC). Right now BMI is marginal VFR, wind from the north-northeast (030°) at 4 knots; CMI is VFR, wind from the northwest (310°) at 6 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.

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 TANGO 4W: moderate turbulence above 18,000 ft from 24,000 ft to 41,000 ft. Over the whole route.
Turbulence AIRMET in force: moderate turbulence from 24,000 ft to 41,000 ft, over the whole route. 7 pilot reports of turbulence near the line in the last three hours: moderate turbulence, at 41,000 ft, 47 nm southwest, 7:11 am CDT (12:11 UTC); light turbulence, at 37,000 ft, 42 nm west, 8:33 am CDT (13:33 UTC). The government's turbulence forecast map ↗
Icing No icing warning in force along the route. A pilot reported no icing, at 26,500 ft, 40 nm southeast, 8:09 am CDT (13:09 UTC). The freezing level is about 15,000 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; 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 BMI.

The eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 1 forecast point nearest it (SPI). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 14th at 12:00 UTC; valid on the 14th at 18:00 UTC for use 14:00 to 21:00 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 BMI 6:17 pm CDT (23:17 UTC), at CMI 6:15 pm CDT (23:15 UTC) (civil twilight ends 6:42 pm CDT (23:42 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.
Radar and forecast charts for the regions crossed government pictures, the latest each time the page loads · the turbulence and icing forecasts: turbulence ↗ · icing ↗
Sources: the Aviation Weather Center's data service (SIGMETs, AIRMETs, graphical AIRMETs, pilot reports, winds and temperatures aloft, observations and terminal forecasts), the National Weather Service radar, the Weather Prediction Center's charts, the FAA's temporary flight restriction list and shapes, and the FAA's airport file for the positions, elevations and magnetic variation. Fetched when the page is viewed and kept a few minutes. Each leg is the straight line between its two airports; airways, terrain and airspace are not considered. The airports in detail: Central IL Rgnl/Bloomington-Normal Airport, University Of Illinois/Willard Airport.
