Lehigh Valley International to Raleigh-Durham International ABE → RDU
327 nautical miles (376 statute miles) southwest on a straight line, true course 210°, about 222° magnetic at the departure end (variation 12W). At 120 knots that is 2 h 22 min at the quickest height in today's winds (4,500 ft, a 18-knot tailwind), arriving about 8:05 am EDT (12:05 UTC). Right now ABE is marginal VFR, wind from the north (350°) at 5 knots; RDU is VFR, wind from the west-southwest (240°) at 6 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: 8 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 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 (AVP, ACY, RIC, RDU). 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.
