John Wayne/Orange County to Tri-Cities Airport SNA → PSC

758 nautical miles (872 statute miles) north on a straight line, true course 356°, about 344° magnetic at the departure end (variation 12E). At 120 knots that is 5 h 30 min at the quickest height in today's winds (34,000 ft, a 18-knot tailwind), arriving about 12:39 am PDT (07:39 UTC), after sunset at the destination. Right now SNA is VFR, wind from the south (180°) at 7 knots; PSC is VFR, wind from the north (010°) at 7 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: 96 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 westbound cruising heights for this course (VFR: even 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 (ONT, WJF, BIH, RNO, BAM, LKV, RDM, YKM). A plus sign is a headwind, a minus sign a tailwind.

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.
