Casper/Natrona County International to Frederick W Smith Intl/Memphis Airport CPR → MEM
900 nautical miles (1,036 statute miles) southeast on a straight line, true course 116°, about 104° magnetic at the departure end (variation 12E). At 120 knots that is 5 h 33 min at the quickest height in today's winds (39,000 ft, a 42-knot tailwind), arriving about 4:00 am CDT (09:00 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: 494 flights in the DOT's last twelve reported months, the route's page.

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.

No temporary flight restriction on or near this route right now.
Daylight
Sunset at CPR 6:28 pm MDT (00:28 UTC), at MEM 6:29 pm CDT (23:29 UTC) (civil twilight ends 6:54 pm CDT (23:54 UTC)). At 120 knots the arrival at MEM is before sunrise there (7:03 am CDT (12:03 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.
