Henry E Rohlsen Airport to Frederick W Smith Intl/Memphis Airport STX → MEM

1,699 nautical miles (1,955 statute miles) northwest on a straight line, true course 313°, about 326° magnetic at the departure end (variation 13W). At 120 knots that is 15 h 10 min at the quickest height in today's winds (4,500 ft, a 8-knot headwind), arriving about 8:53 pm CDT (01:53 UTC), after sunset at the destination. 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: 4 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.

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.

Sunset at STX 5:59 pm AST (21:59 UTC), at MEM 6:29 pm CDT (23:29 UTC) (civil twilight ends 6:54 pm CDT (23:54 UTC)). At 120 knots the arrival at MEM is after sunset there (6:29 pm CDT (23:29 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.
