Atlantic City International to St. Louis Lambert International ACY → STL

736 nautical miles (847 statute miles) west on a straight line, true course 272°, about 282° magnetic at the departure end (variation 10W). At 120 knots that is 6 h 34 min at the quickest height in today's winds (10,500 ft, a 8-knot headwind), arriving about 3:18 am CDT (08:18 UTC), after sunset at the destination. Right now ACY is low IFR, wind from the north-northwest (340°) at 4 knots; STL is VFR, wind from the southeast (130°) 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: 6 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 9 forecast points nearest it (ACY, PSB, EKN, CRW, CMH, CVG, IND, EVV, STL). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 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.
