Ronald Reagan Washington Ntl Airport to Mahlon Sweet Field DCA → EUG

2,073 nautical miles (2,386 statute miles) northwest on a straight line, true course 294°, about 305° magnetic at the departure end (variation 11W). At 120 knots that is 18 h 51 min at the quickest height in today's winds (4,500 ft, a 10-knot headwind), arriving about 2:05 am PDT (09:05 UTC), after sunset at the destination. Right now DCA is marginal VFR, wind from the north (350°) at 10 knots; EUG is VFR, wind variable at 3 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.

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 SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, mist). Over the route from 50 to 189 nm out.
AIRMET SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 100 to 339 nm out.
AIRMET SIERRA 4E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 897 to 1694 nm out.
AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 1385 to 1764 nm out.
AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the route from 1415 to 1744 nm out.
AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the route from 1754 to 2013 nm out.
AIRMET ZULU 2C: moderate icing up to 18,000 ft. Near the route, 1764 nm along 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 DCA.

Winds aloft along the route, and the time en route the forecast for use 14:00–21:00 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 15 forecast points nearest it (RIC, EKN, AGC, CMH, FWA, JOT, DBQ, MCW, FSD, PIR, RAP, BIL, DLN, BOI, RDM). A plus sign is a headwind, a minus sign a tailwind.

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.
