Washington Dulles International to Salt Lake City International IAD → SLC

1,584 nautical miles (1,823 statute miles) west on a straight line, true course 285°, about 295° magnetic at the departure end (variation 10W). At 120 knots that is 14 h 57 min at the quickest height in today's winds (4,500 ft, a 14-knot headwind), arriving about 4:50 pm MDT (22:50 UTC). Right now IAD is VFR, wind calm; SLC is VFR, wind from the south (190°) at 13 knots, gusting to 19. 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: 1,415 flights in the DOT's last twelve reported months, the route's page.

AIRMET in force: 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 428 to 528 nm out. 2 pilot reports of turbulence near the line in the last three hours: light chop turbulence, at 21,000 ft, 41 nm north, 1:50 am EDT (05:50 UTC); light chop turbulence, at 45,000 ft, 49 nm south, 2:53 am EDT (06:53 UTC). The government's turbulence forecast map ↗

Icing AIRMET in force: moderate icing up to 22,000 ft, over the last 349 nm of the route. A pilot reported no icing, at 25,000 ft, 9 nm north, 1:32 am EDT (05:32 UTC). The freezing level is about 13,500 ft (from the winds-aloft temperatures), so icing is possible in cloud above that. The government's icing forecast map ↗

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 IAD.

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 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 (EKN, AGC, CMH, FWA, IND, JOT, SPI, BRL, DSM, OMA, GRI, BFF, DEN, RKS, SLC). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 13th at 00:00 UTC; valid on the 13th 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.

From the FAA's notice service (NOTAMs), the site's copy refreshed every few minutes; last checked 2 minutes ago. The FAA has so far issued eFlight its test feed, which misses some notices (checked against the FAA's own search on 12 October: about a third missing at Santa Barbara and Burbank, none at Atlanta or Las Vegas); the request for the full feed is with the FAA. Times are local to the field. This is for planning; the legal briefing comes from Flight Service or the FAA's own tools.

Sunset at IAD 6:34 pm EDT (22:34 UTC), at SLC 6:49 pm MDT (00:49 UTC) (civil twilight ends 7:16 pm MDT (01:16 UTC)).

Each restriction opens the FAA's own page with the exact area, heights and times.

Colours show wind speed, the moving lines its direction, at the surface unless you pick a height. Map and forecast by Windy.com; a second opinion beside the government's winds-aloft table above.
