Mahlon Sweet Field to St. Cloud Sky Central Airport EUG → STC

1,237 nautical miles (1,424 statute miles) east on a straight line, true course 076°, about 061° magnetic at the departure end (variation 15E). At 120 knots that is 7 h 59 min at the quickest height in today's winds (39,000 ft, a 35-knot tailwind), arriving about 6:20 pm CDT (23:20 UTC). Right now EUG is VFR, wind from the south (180°) at 5 knots; STC is marginal VFR, wind from the east-northeast (060°) at 11 knots, gusting to 18. 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.

Winds aloft along the route, and the time en route the forecast for use 14:00–21:00 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 8 forecast points nearest it (RDM, LWS, DLN, BIL, MLS, DIK, ABR, AXN). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 12:00 UTC; valid on the 12th at 18:00 UTC for use 14:00 to 21:00 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.
