Greenbrier Valley Airport to Tri-Cities Airport LWB → TRI

127 nautical miles (146 statute miles) southwest on a straight line, true course 230°, about 238° magnetic at the departure end (variation 8W). At 120 knots that is 1 h 04 min at the quickest height in today's winds (10,500 ft, no wind along the track), arriving about 11:16 pm EDT (03:16 UTC), after sunset at the destination. Right now LWB is marginal VFR, wind calm; TRI is marginal VFR, wind from the west-southwest (250°) at 10 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: 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.

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.

Daylight

Sunset at LWB 6:48 pm EDT (22:48 UTC), at TRI 6:57 pm EDT (22:57 UTC) (civil twilight ends 7:23 pm EDT (23:23 UTC)). At 120 knots the arrival at TRI is after sunset there (6:59 pm EDT (22:59 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.
