Brown Field Municipal to Laramie Regional SDM → LAR
754 nautical miles (867 statute miles) northeast on a straight line, true course 043°, about 029° magnetic at the departure end (variation 14E). At 120 knots that is 3 h 52 min at the quickest height in today's winds (34,000 ft, a 75-knot tailwind), arriving about 6:52 am MDT (12:52 UTC), after sunset at the destination. Right now SDM is marginal VFR, wind calm; LAR is VFR, wind from the west-southwest (240°) at 18 knots, gusting to 24. 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: 2 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 7 forecast points nearest it (SAN, BLH, LAS, PRC, BCE, GJT, DEN). 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.
