Porterville Municipal to Oakland San Francisco Bay Airport PTV → OAK
183 nautical miles (210 statute miles) northwest on a straight line, true course 305°, about 290° magnetic at the departure end (variation 15E). At 120 knots that is 1 h 22 min at the quickest height in today's winds (4,500 ft, a 14-knot tailwind), arriving about 1:31 am PDT (08:31 UTC), after sunset at the destination. Right now PTV is VFR, wind from the east (090°) at 4 knots; OAK is VFR, wind from the south (180°) at 9 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: 3 flights in the DOT's last twelve reported months, the route's page.

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 above 18,000 ft from 18,000 ft to 39,000 ft. Over the last 67 nm of the route.
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 PTV.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

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.
