Central IL Rgnl/Bloomington-Normal Airport to Appleton International BMI → ATW
228 nautical miles (262 statute miles) north on a straight line, true course 004°, about 007° magnetic at the departure end (variation 3W). At 120 knots that is 1 h 44 min at the quickest height in today's winds (3,500 ft, a 11-knot tailwind), arriving about 5:50 am CDT (10:50 UTC), after sunset at the destination. Right now BMI is VFR, wind from the south-southwest (210°) at 8 knots; ATW is VFR, wind from the south (190°) 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: 50 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 2W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the last 40 nm of the route.
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.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- B739 at 35,000 ft, 37 nm east, 2:05 am CDT (07:05 UTC): no turbulence. 30 nm along the route, 37 nm east of the line.

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 2 forecast points nearest it (JOT, GRB). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th 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.

Temporary flight restrictions on the line or within 25 nm of it
No temporary flight restriction on or near this route right now.
Daylight
Sunset at BMI 6:20 pm CDT (23:20 UTC), at ATW 6:15 pm CDT (23:15 UTC) (civil twilight ends 6:44 pm CDT (23:44 UTC)). At 120 knots the arrival at ATW is before sunrise there (7:04 am CDT (12:04 UTC)).
Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
