Fresno Yosemite International to Logan-Cache Airport FAT → LGU
473 nautical miles (545 statute miles) northeast on a straight line, true course 048°, about 035° magnetic at the departure end (variation 13E). At 120 knots that is 2 h 44 min at the quickest height in today's winds (34,000 ft, a 53-knot tailwind), arriving about 10:41 am MDT (16:41 UTC). Right now FAT is VFR, wind from the southeast (140°) at 9 knots; LGU is VFR, wind from the north (010°) at 7 knots. 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.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 UTC · at 120 knots true airspeed
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 4 forecast points nearest it (FAT, BIH, ELY, SLC). 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.
