Austin-Bergstrom International to City Of Colorado Springs Municipal AUS → COS

623 nautical miles (717 statute miles) northwest on a straight line, true course 328°, about 324° magnetic at the departure end (variation 4E). At 120 knots that is 4 h 25 min at the quickest height in today's winds (4,500 ft, a 21-knot tailwind), arriving about 11:19 pm MDT (05:19 UTC), after sunset at the destination. Right now AUS is VFR, wind from the south-southeast (150°) at 12 knots; COS is VFR, wind from the south-southwest (210°) at 13 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: 9 flights in the DOT's last twelve reported months, the route's page.

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 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 6 forecast points nearest it (SAT, ABI, LBB, AMA, TCC, PUB). 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.
