Chicago Midway International to Trenton Mercer Airport MDW → TTN
592 nautical miles (682 statute miles) east on a straight line, true course 094°, about 098° magnetic at the departure end (variation 4W). At 120 knots that is 3 h 46 min at the quickest height in today's winds (34,000 ft, a 37-knot tailwind), arriving about 2:23 am EDT (06:23 UTC), after sunset at the destination. Right now MDW is VFR, wind from the south (180°) at 5 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.

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