Minneapolis-St Paul Intl/Wold-Chamberlain Airport to Casper/Natrona County International MSP → CPR

584 nautical miles (672 statute miles) west on a straight line, true course 263°, about 263° magnetic at the departure end (variation 0E). At 120 knots that is 4 h 52 min at the quickest height in today's winds (4,500 ft, no wind along the track), arriving about 11:46 pm MDT (05:46 UTC), after sunset at the destination. Right now MSP is VFR, wind from the south-southeast (150°) at 6 knots; CPR is VFR, wind from the northwest (310°) at 16 knots, gusting to 25. 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 20:00–03:00 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 (MSP, AXN, FSD, ABR, PIR, RAP, LND). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 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.
