Gerald R Ford International to Philadelphia International GRR → PHL

497 nautical miles (572 statute miles) east on a straight line, true course 108°, about 114° magnetic at the departure end (variation 6W). At 120 knots that is 3 h 05 min at the quickest height in today's winds (39,000 ft, a 41-knot tailwind), arriving about 1:48 am EDT (05:48 UTC), after sunset at the destination. Right now GRR is VFR, wind from the south (190°) at 6 knots; PHL is IFR, wind from the east-northeast (070°) at 11 knots, gusting to 18. 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: 1,094 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 6 forecast points nearest it (MKG, FWA, CLE, AGC, PSB, 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.
