Laughlin/Bullhead International to Dane County Rgnl/Truax Field IFP → MSN

1,262 nautical miles (1,453 statute miles) northeast on a straight line, true course 060°, about 048° magnetic at the departure end (variation 12E). At 120 knots that is 6 h 56 min at the quickest height in today's winds (34,000 ft, a 62-knot tailwind), arriving about 5:21 am CDT (10:21 UTC), after sunset at the destination. Right now IFP is VFR, wind from the south-southeast (160°) at 15 knots; MSN 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: 31 flights in the DOT's last twelve reported months, the route's page.

  • AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 437 to 477 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 616 to 1103 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 IFP.

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 14 forecast points nearest it (LAS, PRC, BCE, FMN, GJT, ALS, PUB, DEN, GLD, GRI, OMA, DSM, MCW, DBQ). 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.
