Montgomery Regional (Dannelly Field) to Trenton Mercer Airport MGM → TTN

736 nautical miles (847 statute miles) northeast on a straight line, true course 046°, about 047° magnetic at the departure end (variation 1W). At 120 knots that is 4 h 51 min at the quickest height in today's winds (34,000 ft, a 32-knot tailwind), arriving about 3:29 am EDT (07:29 UTC), after sunset at the destination. Right now MGM is VFR, wind from the southwest (230°) at 3 knots; TTN is IFR, wind from the north (360°) at 7 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: 2 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 (MGM, CSG, ATL, GSP, TRI, ROA, RIC, ACY). 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.
