Trenton Mercer Airport to Athens/Ben Epps Airport TTN → AHN

557 nautical miles (641 statute miles) southwest on a straight line, true course 230°, about 242° magnetic at the departure end (variation 12W). At 120 knots that is 4 h 11 min at the quickest height in today's winds (8,500 ft, a 13-knot tailwind), arriving about 9:18 am EDT (13:18 UTC). Right now TTN is IFR, wind from the north (360°) at 6 knots; AHN is VFR, wind from the west (270°) at 4 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 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 5 forecast points nearest it (ACY, RIC, ROA, GSP, ATL). 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.
