City Of Colorado Springs Municipal to James M Cox Dayton International COS → DAY
951 nautical miles (1,094 statute miles) east on a straight line, true course 080°, about 072° magnetic at the departure end (variation 8E). At 120 knots that is 5 h 32 min at the quickest height in today's winds (34,000 ft, a 52-knot tailwind), arriving about 6:46 am EDT (10:46 UTC), after sunset at the destination. Right now COS is VFR, wind from the south (180°) at 11 knots; DAY is marginal VFR, wind from the west (280°) at 4 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: 1 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.

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 9 forecast points nearest it (PUB, GLD, SLN, MKC, COU, BRL, SPI, IND, CVG). 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.
