Tri-Cities Airport to Ronald Reagan Washington Ntl Airport TRI → DCA
292 nautical miles (336 statute miles) northeast on a straight line, true course 059°, about 066° magnetic at the departure end (variation 7W). At 120 knots that is 1 h 47 min at the quickest height in today's winds (34,000 ft, a 43-knot tailwind), arriving about 3:38 am EDT (07:38 UTC), after sunset at the destination. Right now TRI is marginal VFR, wind from the west-southwest (240°) at 10 knots; DCA is marginal VFR, wind from the northwest (320°) at 5 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: 1 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 3 forecast points nearest it (TRI, ROA, RIC). 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.
