Clarence E Page Municipal to Felts Field RCE → SFF
1,136 nautical miles (1,307 statute miles) northwest on a straight line, true course 316°, about 309° magnetic at the departure end (variation 7E). At 120 knots that is 8 h 40 min at the quickest height in today's winds (8,500 ft, a 11-knot tailwind), arriving about 2:27 am PDT (09:27 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: 3 flights in the DOT's last twelve reported months, the route's page.

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.

Sunset at RCE 7:00 pm CDT (00:00 UTC), at SFF 6:07 pm PDT (01:07 UTC) (civil twilight ends 6:38 pm PDT (01:38 UTC)). At 120 knots the arrival at SFF is before sunrise there (7:03 am PDT (14:03 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.
