Tweed/New Haven Airport to Raleigh-Durham International HVN → RDU

426 nautical miles (490 statute miles) southwest on a straight line, true course 222°, about 235° magnetic at the departure end (variation 13W). At 120 knots that is 4 h 18 min at the quickest height in today's winds (4,500 ft, a 21-knot headwind), arriving about 1:44 am EDT (05:44 UTC), after sunset at the destination. Right now HVN is marginal VFR, wind from the northeast (040°) at 8 knots; RDU is VFR, wind from the southwest (230°) at 11 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: 814 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 20:00–03:00 UTC · at 120 knots true airspeed

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 4 forecast points nearest it (JFK, ACY, RIC, RDU). 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.
