Piedmont Triad International to Northeast Philadelphia Airport GSO → PNE
334 nautical miles (384 statute miles) northeast on a straight line, true course 043°, about 051° magnetic at the departure end (variation 8W). At 120 knots that is 2 h 23 min at the quickest height in today's winds (39,000 ft, a 20-knot tailwind), arriving about 7:05 am EDT (11:05 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 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.
Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of
- AIRMET TANGO 5W: moderate turbulence below 18,000 ft (due to mountain wave) up to 10,000 ft. Over the first 206 nm of the route.
- AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Near the route, 39 nm along the route.
- AIRMET SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist, fog). Over the last 206 nm of the route.
- AIRMET TANGO 3W: moderate turbulence above 18,000 ft (due to mountain wave) from 30,000 ft to 41,000 ft. Near the route, 206 nm along the route.
- AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 21,000 ft to 33,000 ft. Over the last 108 nm of the route.
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 GSO.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- C560 at 13,000 ft, 18 nm northwest, 2:38 am EDT (06:38 UTC): moderate turbulence, overcast above 19,000 ft, heavy rain, remarks: during the descent. 314 nm along the route, 18 nm northwest of the line.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 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 4 forecast points nearest it (RDU, ROA, RIC, ACY). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
