Aspen-Pitkin County/Sardy Field to Waukegan Ntl Airport ASE → UGN
882 nautical miles (1,015 statute miles) east on a straight line, true course 071°, about 062° magnetic at the departure end (variation 9E). At 120 knots that is 5 h 01 min at the quickest height in today's winds (39,000 ft, a 56-knot tailwind), arriving about 12:15 am CDT (05:15 UTC), after sunset at the destination. 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: 8 flights in the DOT's last twelve reported months, the route's page.

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 7 forecast points nearest it (DEN, GLD, GRI, OMA, DSM, DBQ, JOT). 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.

Daylight
Sunset at ASE 6:33 pm MDT (00:33 UTC), at UGN 6:16 pm CDT (23:16 UTC) (civil twilight ends 6:44 pm CDT (23:44 UTC)). At 120 knots the arrival at UGN is before sunrise there (7:00 am CDT (12:00 UTC)).
Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
