Van Nuys Airport to Joslin Fld/Magic Valley Regional VNY → TWF
531 nautical miles (611 statute miles) north on a straight line, true course 020°, about 008° magnetic at the departure end (variation 12E). At 120 knots that is 3 h 02 min at the quickest height in today's winds (34,000 ft, a 55-knot tailwind), arriving about 6:03 am MDT (12:03 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.

The eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 5 forecast points nearest it (WJF, BIH, ELY, BAM, PIH). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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 VNY 6:22 pm PDT (01:22 UTC), at TWF 6:59 pm MDT (00:59 UTC) (civil twilight ends 7:27 pm MDT (01:27 UTC)). At 120 knots the arrival at TWF is before sunrise there (7:47 am MDT (13:47 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.
