Rapid City Regional to Lawton-Fort Sill Regional RAP → LAW

608 nautical miles (700 statute miles) south on a straight line, true course 158°, about 150° magnetic at the departure end (variation 8E). At 120 knots that is 4 h 52 min at the quickest height in today's winds (39,000 ft, a 5-knot tailwind), arriving about 6:35 am CDT (11:35 UTC), after sunset at the destination. Right now RAP is low IFR, wind from the northwest (320°) at 5 knots; LAW is VFR, wind from the south-southeast (160°) at 9 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.

  • 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). Near the route, at the departure end.
  • AIRMET TANGO 4W: moderate turbulence above 18,000 ft from 18,000 ft to 38,000 ft. Near the route, at the departure end.
  • 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 90 to 588 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 RAP.

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.

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.

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

Daylight

Sunset at RAP 6:12 pm MDT (00:12 UTC), at LAW 7:01 pm CDT (00:01 UTC) (civil twilight ends 7:27 pm CDT (00:27 UTC)). At 120 knots the arrival at LAW is before sunrise there (7:36 am CDT (12:36 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.
