Pierre Regional to Joe Foss Field PIR → FSD
160 nautical miles (185 statute miles) east on a straight line, true course 106°, about 098° magnetic at the departure end (variation 8E). At 120 knots that is 57 min at the quickest height in today's winds (39,000 ft, a 49-knot tailwind), arriving about 7:34 am CDT (12:34 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: 496 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.
Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of
- SIGMET C17C: thunderstorms (a convective SIGMET) up to 36,000 ft, moving from the southwest at 40 knots, until 7:55 am CDT (12:55 UTC). Near the route, at the departure end.

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 2 forecast points nearest it (PIR, FSD). A plus sign is a headwind, a minus sign a tailwind.

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.

Daylight
Sunset at PIR 7:00 pm CDT (00:00 UTC), at FSD 6:49 pm CDT (23:49 UTC) (civil twilight ends 7:17 pm CDT (00:17 UTC)). At 120 knots the arrival at FSD is before sunrise there (7:37 am CDT (12:37 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.
