Salt Lake City International to Missoula Montana Airport SLC → MSO
379 nautical miles (436 statute miles) north on a straight line, true course 347°, about 336° magnetic at the departure end (variation 11E). At 120 knots that is 2 h 06 min at the quickest height in today's winds (30,000 ft, a 60-knot tailwind), arriving about 8:38 pm MDT (02:38 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: 2,097 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 4 forecast points nearest it (SLC, PIH, DLN, GPI). 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 SLC 6:52 pm MDT (00:52 UTC), at MSO 6:54 pm MDT (00:54 UTC) (civil twilight ends 7:25 pm MDT (01:25 UTC)). At 120 knots the arrival at MSO is after sunset there (6:56 pm MDT (00:56 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.
