Kansas City International to Louisville Muhammad Ali International MCI → SDF

426 nautical miles (490 statute miles) east on a straight line, true course 096°, about 094° magnetic at the departure end (variation 2E). At 120 knots that is 2 h 33 min at the quickest height in today's winds (39,000 ft, a 47-knot tailwind), arriving about 12:29 am EDT (04:29 UTC), after sunset at the destination. Right now MCI is VFR, wind from the south (170°) at 9 knots; SDF is VFR, wind from the southwest (220°) 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: 1,165 flights in the DOT's last twelve reported months, the route's page.

The return flight

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 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 first 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 MCI.

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

  • B38M at 23,700 ft, 34 nm north, 6:51 pm CDT (23:51 UTC): light turbulence. 337 nm along the route, 34 nm north of the line.

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 5 forecast points nearest it (MKC, COU, STL, EVV, LOU). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 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 MCI 6:44 pm CDT (23:44 UTC), at SDF 7:09 pm EDT (23:09 UTC) (civil twilight ends 7:36 pm EDT (23:36 UTC)). At 120 knots the arrival at SDF is before sunrise there (7:48 am EDT (11:48 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.
