City Of Colorado Springs Municipal to Reno/Tahoe International COS → RNO
702 nautical miles (808 statute miles) west on a straight line, true course 278°, about 270° magnetic at the departure end (variation 8E). At 120 knots that is 6 h 30 min at the quickest height in today's winds (8,500 ft, a 12-knot headwind), arriving about 11:56 pm PDT (06:56 UTC), after sunset at the destination. Right now COS is VFR, wind from the south-southwest (210°) at 13 knots; RNO is VFR, wind from the north-northeast (020°) at 11 knots, gusting to 14. 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: 9 flights in the DOT's last twelve reported months, the route's page.

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 7 forecast points nearest it (PUB, DEN, GJT, SLC, ELY, BAM, RNO). 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.
