University Of Illinois/Willard Airport to Piedmont Triad International CMI → GSO
459 nautical miles (528 statute miles) southeast on a straight line, true course 118°, about 121° magnetic at the departure end (variation 3W). At 120 knots that is 2 h 43 min at the quickest height in today's winds (34,000 ft, a 49-knot tailwind), arriving about 6:32 am EDT (10:32 UTC), after sunset at the destination. Right now CMI is VFR, wind from the south (190°) at 6 knots; GSO is VFR, wind from the west-southwest (240°) 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: 2 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 SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist), from 1:00 am CDT (06:00 UTC). Over the route from 50 to 399 nm out.
- AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist), from 1:00 am CDT (06:00 UTC). Over the route from 279 to 419 nm out.
- AIRMET TANGO 5W: moderate turbulence below 18,000 ft (due to mountain wave) up to 10,000 ft, from 1:00 am CDT (06:00 UTC). Over the last 90 nm of the route.
- AIRMET TANGO 5W: moderate turbulence above 18,000 ft (due to mountain wave) from 29,000 ft to 40,000 ft, from 1:00 am CDT (06:00 UTC). Over the route from 429 to 429 nm out.
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 CMI.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- B38M at 29,000 ft, 33 nm north, 11:52 pm CDT (04:52 UTC): no turbulence from 23,000 ft to 29,000 ft. At the departure end, 33 nm north of the line.

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, CRW, TRI, ROA, RDU). 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.
