General Mitchell International to Boise Air Trml/Gowen Field MKE → BOI

1,233 nautical miles (1,419 statute miles) west on a straight line, true course 281°, about 285° magnetic at the departure end (variation 4W). At 120 knots that is 11 h 38 min at the quickest height in today's winds (4,500 ft, a 14-knot headwind), arriving about 7:41 pm MDT (01:41 UTC), after sunset at the destination. Right now MKE is VFR, wind from the south-southwest (210°) at 9 knots; BOI is VFR, wind from the northwest (310°) at 4 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 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 288 to 1164 nm out.
  • AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 835 to 1193 nm out.
  • AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the last 368 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 MKE.

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

  • B39M at 36,000 ft, 44 nm south, 8:18 am CDT (13:18 UTC): no turbulence. At the departure end, 44 nm south of the line.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 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 10 forecast points nearest it (GRB, DBQ, LSE, MCW, FSD, PIR, RAP, LND, PIH, BOI). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.

Daylight

Sunset at MKE 6:14 pm CDT (23:14 UTC), at BOI 7:05 pm MDT (01:05 UTC) (civil twilight ends 7:33 pm MDT (01:33 UTC)). At 120 knots the arrival at BOI is after sunset there (7:06 pm MDT (01:06 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.
