Columbia Regional to Bill And Hillary Clinton Ntl/Adams Field COU → LIT
245 nautical miles (282 statute miles) south on a straight line, true course 180°, about 180° magnetic at the departure end (variation 0E). At 120 knots that is 1 h 47 min at the quickest height in today's winds (39,000 ft, a 18-knot tailwind), arriving about 11:59 pm CDT (04:59 UTC), after sunset at the destination. Right now COU is VFR, wind from the south (190°) at 6 knots; LIT is VFR, wind from the west (270°) at 3 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.
The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words
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
No SIGMET or AIRMET covers any part of this route right now.
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 COU.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- C750 at 43,000 ft, 5 nm northeast, 7:50 pm CDT (00:50 UTC): light to moderate chop turbulence above 43,000 ft, remarks: zme. 226 nm along the route, 5 nm northeast 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 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 3 forecast points nearest it (COU, SGF, LIT). 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.
