Chicago O'Hare International to Yampa Valley Airport ORD → HDN
875 nautical miles (1,007 statute miles) west on a straight line, true course 271°, about 274° magnetic at the departure end (variation 3W). At 120 knots that is 7 h 57 min at the quickest height in today's winds (4,500 ft, a 10-knot headwind), arriving about 3:36 am MDT (09:36 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: 352 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 7 forecast points nearest it (JOT, DBQ, DSM, OMA, GRI, BFF, DEN). 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 ORD 6:15 pm CDT (23:15 UTC), at HDN 6:33 pm MDT (00:33 UTC) (civil twilight ends 7:01 pm MDT (01:01 UTC)). At 120 knots the arrival at HDN is before sunrise there (7:16 am MDT (13:16 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.
