Tucson International to Spokane International TUS → GEG
978 nautical miles (1,126 statute miles) north on a straight line, true course 344°, about 335° magnetic at the departure end (variation 9E). At 120 knots that is 6 h 09 min at the quickest height in today's winds (24,000 ft, a 39-knot tailwind), arriving about 6:13 am PDT (13:13 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: 1 flights in the DOT's last twelve reported months, the route's page.

A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from TUS.

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.

Sunset at TUS 5:53 pm MST (00:53 UTC), at GEG 6:06 pm PDT (01:06 UTC) (civil twilight ends 6:37 pm PDT (01:37 UTC)). At 120 knots the arrival at GEG is before sunrise there (7:04 am PDT (14:04 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.
