Trenton Mercer Airport to Chicago O'Hare International TTN → ORD
600 nautical miles (691 statute miles) west on a straight line, true course 284°, about 296° magnetic at the departure end (variation 12W). At 120 knots that is 5 h 21 min at the quickest height in today's winds (4,500 ft, a 8-knot headwind), arriving about 3:06 am CDT (08:06 UTC), after sunset at the destination. Right now TTN is IFR, wind from the north (360°) at 7 knots; ORD is VFR, wind from the south-southeast (150°) 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: 5 flights in the DOT's last twelve reported months, the route's page.

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 6 forecast points nearest it (AVP, PSB, AGC, CLE, FWA, JOT). 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.
