City Of Colorado Springs Municipal to Blue Grass Airport COS → LEX
944 nautical miles (1,087 statute miles) east on a straight line, true course 086°, about 078° magnetic at the departure end (variation 8E). At 120 knots that is 5 h 39 min at the quickest height in today's winds (39,000 ft, a 47-knot tailwind), arriving about 3:52 am EDT (07:52 UTC), after sunset at the destination. 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
- SIGMET 6W: thunderstorms (a convective SIGMET) up to 34,000 ft, moving from the southwest at 40 knots, until 9:55 pm MDT (03:55 UTC). Near the route, at the departure end.

Winds aloft along the route, and the time en route the forecast for use 20:00–03:00 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 9 forecast points nearest it (PUB, GLD, GCK, SLN, MKC, COU, STL, EVV, LOU). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 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.
