Grayling Airport to Heber Valley Airport KGX → HCR

2,174 nautical miles (2,501 statute miles) east on a straight line, true course 105°, about 093° magnetic at the departure end (variation 12E). At 120 knots that is 13 h 20 min at the quickest height in today's winds (34,000 ft, a 43-knot tailwind), arriving about 10:54 am MDT (16:54 UTC). 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: 179 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.

  • AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the route from 1526 to 1675 nm out.
  • AIRMET ZULU 2C: moderate icing up to 20,000 ft. Over the route from 1555 to 1855 nm out.
  • AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the last 439 nm of the route.
  • AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 36,000 ft. Over the route from 1795 to 1914 nm out.
  • AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the last 309 nm of the route.
  • 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 1914 to 1944 nm out.
  • AIRMET TANGO 4W: moderate turbulence above 18,000 ft from 18,000 ft to 36,000 ft. Over the last 50 nm of the route.
  • AIRMET TANGO 4W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the last 20 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 KGX.

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.
