Philadelphia International to Los Angeles International PHL → LAX

2,082 nautical miles (2,396 statute miles) west on a straight line, true course 274°, about 286° magnetic at the departure end (variation 12W). At 120 knots that is 19 h 06 min at the quickest height in today's winds (4,500 ft, a 11-knot headwind), arriving about 2:06 pm PDT (21:06 UTC). Right now PHL is IFR, wind from the east-northeast (070°) at 11 knots, gusting to 18; LAX is VFR, wind from the west (260°) 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: 4,764 flights in the DOT's last twelve reported months, the route's page.

AIRMET SIERRA 6E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the last 90 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 PHL.

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 18 forecast points nearest it (ACY, PSB, AGC, CMH, CVG, IND, SPI, COU, MKC, SLN, GCK, GLD, PUB, ALS, FMN, PRC, LAS, ONT). 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.
