Charlottesville-Albemarle Airport to San Antonio International CHO → SAT
1,121 nautical miles (1,290 statute miles) west on a straight line, true course 249°, about 257° magnetic at the departure end (variation 8W). At 120 knots that is 10 h 01 min at the quickest height in today's winds (4,500 ft, a 8-knot headwind), arriving about 5:48 am CDT (10:48 UTC), after sunset at the destination. 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 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 10 forecast points nearest it (ROA, TRI, TYS, BNA, HSV, MEM, JAN, SHV, CLL, SAT). 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.

Sunset at CHO 6:40 pm EDT (22:40 UTC), at SAT 7:06 pm CDT (00:06 UTC) (civil twilight ends 7:30 pm CDT (00:30 UTC)). At 120 knots the arrival at SAT is before sunrise there (7:33 am CDT (12:33 UTC)).
Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
