Raleigh-Durham International to Piedmont Triad International RDU → GSO
58 nautical miles (66 statute miles) west on a straight line, true course 284°, about 293° magnetic at the departure end (variation 9W). At 120 knots that is 34 min at the quickest height in today's winds (4,500 ft, a 19-knot headwind), arriving about 10:40 pm EDT (02:40 UTC), after sunset at the destination. Right now RDU is VFR, wind from the southwest (230°) at 12 knots; GSO is VFR, wind from the west-southwest (240°) 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: 114 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 8,000 ft. Over the last 10 nm of the route.
- AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Near the route, at the destination end.
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 RDU.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- B763 at 3,000 ft, 7 nm northeast, 7:26 pm EDT (23:26 UTC): a broken layer above 3,000 ft. At the destination end, 7 nm northeast of the line.

Winds aloft along the route, and the time en route the forecast for use 20:00–03:00 UTC · at 120 knots true airspeed
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 1 forecast point nearest it (RDU). 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.
