Corpus Christi International to Cyril E King Airport CRP → STT

1,878 nautical miles (2,161 statute miles) east on a straight line, true course 100°, about 096° magnetic at the departure end (variation 4E). At 120 knots that is 13 h 25 min at the quickest height in today's winds (34,000 ft, a 20-knot tailwind), arriving about 11:26 pm AST (03:26 UTC), after sunset at the destination. Right now CRP is VFR, wind from the south-southeast (150°) at 10 knots; STT is VFR, wind from the southeast (130°) at 10 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 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 08:00–15:00 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 7 forecast points nearest it (CRP, PSX, LCH, MSY, PIE, EYW, MIA). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
