Rapid City Regional to Santa FE Regional RAP → SAF

525 nautical miles (604 statute miles) south on a straight line, true course 196°, about 188° magnetic at the departure end (variation 8E). At 120 knots that is 5 h 35 min at the quickest height in today's winds (8,500 ft, a 26-knot headwind), arriving about 1:48 am MDT (07:48 UTC), after sunset at the destination. Right now RAP is low IFR, wind from the east (090°) at 7 knots; SAF is VFR, wind from the south (180°) at 12 knots, gusting to 20. 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.

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.
