Roswell Air Center Airport to Cheyenne Rgnl/Jerry Olson Field ROW → CYS

472 nautical miles (543 statute miles) north on a straight line, true course 358°, about 348° magnetic at the departure end (variation 10E). At 120 knots that is 3 h 03 min at the quickest height in today's winds (30,000 ft, a 35-knot tailwind), arriving about 2:20 am MDT (08:20 UTC), after sunset at the destination. Right now ROW is VFR, wind from the south-southwest (210°) at 12 knots; CYS is VFR, wind from the west (270°) at 9 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 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 5 forecast points nearest it (ROW, TCC, ALS, PUB, DEN). 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.
