Logan-Cache Airport to Fresno Yosemite International LGU → FAT
473 nautical miles (545 statute miles) southwest on a straight line, true course 233°, about 222° magnetic at the departure end (variation 11E). At 120 knots that is 4 h 01 min at the quickest height in today's winds (4,500 ft, a 2-knot headwind), arriving about 11:40 am PDT (18:40 UTC). Right now LGU is VFR, wind from the north (010°) at 7 knots; FAT is VFR, wind from the southeast (140°) at 9 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 14:00–21:00 UTC · at 120 knots true airspeed
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, ELY, BIH, FAT). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 12:00 UTC; valid on the 12th at 18:00 UTC for use 14:00 to 21:00 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.
