Harry Reid International to Appleton International LAS → ATW

1,310 nautical miles (1,507 statute miles) northeast on a straight line, true course 060°, about 049° magnetic at the departure end (variation 11E). At 120 knots that is 7 h 34 min at the quickest height in today's winds (39,000 ft, a 53-knot tailwind), arriving about 10:55 am CDT (15:55 UTC). Right now LAS is VFR, wind from the south (170°) at 8 knots; ATW is VFR, wind from the south-southwest (200°) 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: 340 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 02:00–09:00 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 10 forecast points nearest it (LAS, BCE, GJT, DEN, BFF, ONL, FSD, MCW, LSE, GRB). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 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.
