City Of Colorado Springs Municipal to Durango-La Plata County COS → DRO
175 nautical miles (202 statute miles) southwest on a straight line, true course 236°, about 228° magnetic at the departure end (variation 8E). At 120 knots that is 2 h 02 min at the quickest height in today's winds (10,500 ft, a 34-knot headwind), arriving about 1:14 am MDT (07:14 UTC), after sunset at the destination. Right now COS is VFR, wind from the south (180°) at 11 knots; DRO is VFR, wind from the south-southwest (210°) at 5 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: 7 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 3 forecast points nearest it (PUB, ALS, FMN). 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.
