Napa County to Van Nuys Airport APC → VNY

302 nautical miles (348 statute miles) southeast on a straight line, true course 141°, about 126° magnetic at the departure end (variation 15E). At 120 knots that is 2 h 24 min at the quickest height in today's winds (18,000 ft, a 6-knot tailwind), arriving about 6:56 pm PDT (01:56 UTC), after sunset at the destination. Right now APC is VFR, wind from the south (190°) at 18 knots, gusting to 24; VNY is VFR, wind from the south (180°) at 10 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: 11 flights in the DOT's last twelve reported months, the route's page.

The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words

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 TANGO 1W: moderate turbulence below 18,000 ft (due to mountain wave) up to 12,000 ft. Near the route, at the destination end.
AIRMET SIERRA 6E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Near the route, at the destination end.

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 APC.

Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

B737 at 14,000 ft, 49 nm east, 2:54 pm PDT (21:54 UTC): moderate turbulence. At the destination end, 49 nm east of the line.

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 4 forecast points nearest it (SFO, FAT, SBA, WJF). 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.
