University Of Illinois/Willard Airport to Baltimore/Washington International Thurgood Marshall CMI → BWI
539 nautical miles (620 statute miles) east on a straight line, true course 092°, about 095° magnetic at the departure end (variation 3W). At 120 knots that is 3 h 25 min at the quickest height in today's winds (34,000 ft, a 38-knot tailwind), arriving about 6:10 am EDT (10:10 UTC), after sunset at the destination. Right now CMI is VFR, wind from the south-southwest (200°) at 6 knots; BWI is IFR, wind from the north-northeast (020°) 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: 10 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
- SIGMET E22E: thunderstorms (a convective SIGMET) up to 40,000 ft, moving from the southwest at 20 knots, until 2:55 am CDT (07:55 UTC). Over the last 80 nm of the route.

Winds aloft along the route, and the time en route the forecast for use 02:00–09:00 UTC · at 120 knots true airspeed
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 6 forecast points nearest it (IND, CVG, CMH, AGC, EKN, RIC). A plus sign is a headwind, a minus sign a tailwind.

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