Sacramento International to San Antonio International SMF → SAT

1,269 nautical miles (1,461 statute miles) east on a straight line, true course 109°, about 096° magnetic at the departure end (variation 13E). At 120 knots that is 8 h 49 min at the quickest height in today's winds (34,000 ft, a 24-knot tailwind), arriving about 6:35 pm CDT (23:35 UTC). Right now SMF is VFR, wind calm; SAT is marginal VFR, wind from the east-southeast (110°) at 4 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: 6 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 14:00–21:00 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 (SAC, BIH, LAS, PRC, FMN, ABQ, ROW, INK, DRT, SAT). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 12:00 UTC; valid on the 12th at 18:00 UTC for use 14:00 to 21:00 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.
