Sioux Gateway/Brig General Bud Day Field to St. George Regional SUX → SGU

852 nautical miles (981 statute miles) west on a straight line, true course 253°, about 250° magnetic at the departure end (variation 3E). At 120 knots that is 8 h 58 min at the quickest height in today's winds (10,500 ft, a 25-knot headwind), arriving about 11:59 am MDT (17:59 UTC). Right now SUX is VFR, wind calm; SGU is VFR, wind from the southwest (220°) at 12 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 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 (OMA, ONL, GLD, BFF, DEN, GJT, BCE). 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.
