Frederick Douglass/Greater Rochester International to Philadelphia International ROC → PHL
223 nautical miles (257 statute miles) southeast on a straight line, true course 150°, about 162° magnetic at the departure end (variation 12W). At 120 knots that is 1 h 53 min at the quickest height in today's winds (9,500 ft, a 2-knot headwind), arriving about 10:43 pm EDT (02:43 UTC), after sunset at the destination. 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: 2,537 flights in the DOT's last twelve reported months, the route's page.

Green, blue, red and purple airport dots are the flying conditions reported there now (VFR, marginal VFR, IFR, low IFR); grey means no report. Red areas are SIGMETs, orange areas AIRMETs, hatched red areas temporary flight restrictions. Map tiles: OpenFreeMap, data © OpenStreetMap contributors.

A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from ROC.

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.

Sunset at ROC 6:33 pm EDT (22:33 UTC), at PHL 6:26 pm EDT (22:26 UTC) (civil twilight ends 6:53 pm EDT (22:53 UTC)). At 120 knots the arrival at PHL is after sunset there (6:27 pm EDT (22:27 UTC)).
Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
