Jackson Hole Airport to Chicago/Rockford International JAC → RFD

953 nautical miles (1,096 statute miles) east on a straight line, true course 088°, about 075° magnetic at the departure end (variation 13E). At 120 knots that is 5 h 27 min at the quickest height in today's winds (39,000 ft, a 55-knot tailwind), arriving about 7:54 am CDT (12:54 UTC). Right now JAC is VFR, wind from the southwest (220°) at 6 knots; RFD is VFR, wind from the south (170°) at 3 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.

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

  • SIGMET C13C: thunderstorms (a convective SIGMET) up to 30,000 ft, moving from the southwest at 40 knots, until 2:55 am MDT (08:55 UTC). Near the route, 347 nm along 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 route from 89 to 308 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 675 to 903 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 JAC.

Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

No pilot reports within 50 nautical miles of the line in the last three hours.

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 8 forecast points nearest it (LND, RAP, PIR, ONL, FSD, MCW, DBQ, JOT). A plus sign is a headwind, a minus sign a tailwind.

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.
