Charles M Schulz/Sonoma County to Northern Colorado Regional STS → FNL
832 nautical miles (957 statute miles) east on a straight line, true course 076°, about 060° magnetic at the departure end (variation 16E). At 120 knots that is 5 h 08 min at the quickest height in today's winds (34,000 ft, a 42-knot tailwind), arriving about 5:51 am MDT (11:51 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: 2 flights in the DOT's last twelve reported months, the route's page.

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 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 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.
