Tucson International to Bozeman Yellowstone International TUS → BZN

820 nautical miles (944 statute miles) north on a straight line, true course 359°, about 350° magnetic at the departure end (variation 9E). At 120 knots that is 4 h 25 min at the quickest height in today's winds (30,000 ft, a 66-knot tailwind), arriving about 12:39 pm MDT (18:39 UTC). Right now TUS is VFR, wind from the south (180°) at 7 knots; BZN is low IFR, wind from the southwest (220°) at 4 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 7 forecast points nearest it (TUS, PHX, PRC, BCE, SLC, PIH, DLN). 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.
