Seattle-Tacoma International to Manhattan Regional SEA → MHK

1,219 nautical miles (1,403 statute miles) east on a straight line, true course 105°, about 089° magnetic at the departure end (variation 16E). At 120 knots that is 8 h 18 min at the quickest height in today's winds (39,000 ft, a 27-knot tailwind), arriving about 5:53 am CDT (10:53 UTC), after sunset at the destination. Right now SEA is VFR, wind from the north (360°) at 7 knots; MHK is VFR, wind from the south-southwest (200°) at 11 knots, gusting to 20. 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.

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.

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 SEA.

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.

Temporary flight restrictions on the line or within 25 nm of it

No temporary flight restriction on or near this route right now.

Daylight

Sunset at SEA 6:27 pm PDT (01:27 UTC), at MHK 6:52 pm CDT (23:52 UTC) (civil twilight ends 7:19 pm CDT (00:19 UTC)). At 120 knots the arrival at MHK is before sunrise there (7:33 am CDT (12:33 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.
