Williston Basin International to Dickinson/Theodore Roosevelt Regional XWA → DIK
96 nautical miles (110 statute miles) southeast on a straight line, true course 156°, about 148° magnetic at the departure end (variation 8E). At 120 knots that is 46 min at the quickest height in today's winds (39,000 ft, a 5-knot tailwind), arriving about 3:49 am MDT (09:49 UTC), after sunset at the destination. Right now XWA is IFR, wind from the northeast (050°) at 14 knots; DIK is low IFR, wind from the east-northeast (060°) at 13 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: 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.
Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of
- AIRMET SIERRA 4E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the whole route.
- AIRMET ZULU 2C: moderate icing up to 18,000 ft. Over the first 19 nm of the route.
- AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the route from 29 to 67 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 XWA.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- BE20 at 15,000 ft, 4 nm north, 3:00 am CDT (08:00 UTC): light icing, 0 °C. At the destination end, 4 nm north of the line.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 UTC · at 120 knots true airspeed
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 1 forecast point nearest it (DIK). 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.
