Charleston Afb/Intl Airport to Tweed/New Haven Airport CHS → HVN
607 nautical miles (699 statute miles) northeast on a straight line, true course 032°, about 039° magnetic at the departure end (variation 7W). At 120 knots that is 2 h 55 min at the quickest height in today's winds (34,000 ft, a 88-knot tailwind), arriving about 4:14 am EDT (08:14 UTC), after sunset at the destination. Right now CHS is VFR, wind from the west-southwest (250°) at 4 knots; HVN is marginal VFR, wind from the north-northeast (020°) at 16 knots, gusting to 23. 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: 459 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 02:00–09:00 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 8 forecast points nearest it (CHS, FLO, ILM, RDU, ORF, ACY, JFK, BDL). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 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.
