Felts Field to Clarence E Page Municipal SFF → RCE

1,136 nautical miles (1,307 statute miles) southeast on a straight line, true course 123°, about 107° magnetic at the departure end (variation 16E). At 120 knots that is 7 h 57 min at the quickest height in today's winds (39,000 ft, a 23-knot tailwind), arriving about 2:26 am CDT (07:26 UTC), after sunset at the destination. Right now SFF is VFR, wind from the north (010°) at 10 knots, gusting to 18; RCE is VFR, wind from the south (180°) at 19 knots, gusting to 28. 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: 3 flights in the DOT's last twelve reported months, the route's page.

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 (GEG, LWS, DLN, LND, BFF, DEN, GLD, GCK, GAG, OKC). 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.
