Chicago O'Hare International to Rapid City Regional ORD → RAP
676 nautical miles (777 statute miles) west on a straight line, true course 286°, about 289° magnetic at the departure end (variation 3W). At 120 knots that is 5 h 56 min at the quickest height in today's winds (4,500 ft, a 6-knot headwind), arriving about 11:44 pm MDT (05:44 UTC), after sunset at the destination. Right now ORD is VFR, wind from the southwest (220°) at 7 knots; RAP is marginal VFR, wind from the north-northeast (030°) at 8 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: 1,357 flights in the DOT's last twelve reported months, the route's page.

- AIRMET TANGO 4W: moderate turbulence above 18,000 ft from 18,000 ft to 36,000 ft. Over the last 0 nm of the route.
A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from ORD.

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 (JOT, DBQ, MCW, FSD, ONL, PIR, RAP). 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.
