Nampa Municipal to Washington Dulles International MAN → IAD

1,768 nautical miles (2,035 statute miles) east on a straight line, true course 085°, about 069° magnetic at the departure end (variation 16E). At 120 knots that is 10 h 31 min at the quickest height in today's winds (39,000 ft, a 48-knot tailwind), arriving about 8:26 am EDT (12:26 UTC). Right now MAN is VFR, wind from the west-northwest (300°) at 9 knots; IAD is IFR, wind from the north (350°) at 6 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.

AIRMET TANGO 4W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the route from 230 to 499 nm out.
AIRMET TANGO 1W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 270 to 460 nm out.
AIRMET TANGO 3W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 919 to 1069 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 last 330 nm of the route.
AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 1598 to 1738 nm out.
AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 21,000 ft to 33,000 ft. Over the last 120 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 MAN.

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 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 15 forecast points nearest it (BOI, PIH, LND, RAP, PIR, ONL, FSD, MCW, DBQ, JOT, FWA, CMH, AGC, EKN, RIC). 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.
