Charles M Schulz/Sonoma County to Denver International STS → DEN
847 nautical miles (974 statute miles) east on a straight line, true course 079°, about 063° magnetic at the departure end (variation 16E). At 120 knots that is 4 h 55 min at the quickest height in today's winds (34,000 ft, a 52-knot tailwind), arriving about 12:39 am MDT (06:39 UTC), after sunset at the destination. Right now STS is VFR, wind from the south (180°) at 7 knots; DEN is VFR, wind from the south (170°) 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: 32 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 20:00–03:00 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 7 forecast points nearest it (SAC, RNO, BAM, ELY, SLC, GJT, DEN). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 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.

Fetched when the page is viewed and kept a few minutes. Each leg is the straight line between its two airports; airways, terrain and airspace are not considered.
