Seattle Paine Field International to Denver International PAE → DEN

899 nautical miles (1,034 statute miles) southeast on a straight line, true course 116°, about 100° magnetic at the departure end (variation 16E). At 120 knots that is 6 h 49 min at the quickest height in today's winds (39,000 ft, a 12-knot tailwind), arriving about 6:48 am MDT (12:48 UTC), after sunset at the destination. 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: 82 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 TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the first 190 nm of the route.
  • AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the route from 130 to 350 nm out.
  • AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 210 to 789 nm out.
  • AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 36,000 ft. Over the route from 280 to 459 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 290 to 469 nm out.
  • AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the route from 360 to 759 nm out.
  • AIRMET TANGO 4W: moderate turbulence above 18,000 ft from 18,000 ft to 38,000 ft. Over the last 290 nm of the route.
  • AIRMET TANGO 4W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the last 290 nm of the route.
  • AIRMET TANGO 5W: strong surface winds (30 knots or more) (due to sustained surface winds greater than 30 knots). Over the route from 669 to 749 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 679 to 859 nm out.

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 PAE.

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.

No temporary flight restriction on or near this route right now.

Daylight

Sunset at PAE 6:26 pm PDT (01:26 UTC), at DEN 6:24 pm MDT (00:24 UTC) (civil twilight ends 6:51 pm MDT (00:51 UTC)). At 120 knots the arrival at DEN is before sunrise there (7:05 am MDT (13:05 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.
