New York Stewart International to Yampa Valley Airport SWF → HDN

1,493 nautical miles (1,718 statute miles) west on a straight line, true course 279°, about 293° magnetic at the departure end (variation 14W). At 120 knots that is 14 h 05 min at the quickest height in today's winds (6,500 ft, a 14-knot headwind), arriving about 1:30 pm MDT (19:30 UTC). Right now SWF is marginal VFR, wind from the north-northeast (030°) at 7 knots; HDN is VFR, wind from the south (180°) 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: 2 flights in the DOT's last twelve reported months, the route's page.

The return flight

The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words

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 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the first 567 nm of the route.
  • AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 21,000 ft to 33,000 ft. Over the first 179 nm of the route.
  • AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 30 to 229 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 716 to 1304 nm out.
  • AIRMET TANGO 4W: moderate turbulence above 18,000 ft from 18,000 ft to 38,000 ft. Over the last 219 nm of the route.
  • AIRMET TANGO 4W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the last 169 nm of the route.
  • 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 last 90 nm of the route.
  • AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the last 10 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 SWF.

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 14 forecast points nearest it (AVP, PSB, BUF, CLE, FWA, MKG, JOT, DBQ, DSM, OMA, GRI, ONL, BFF, DEN). 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.
