Jack Northrop Fld/Hawthorne Municipal to Bishop Airport HHR → BIH
207 nautical miles (238 statute miles) north on a straight line, true course 360°, about 346° magnetic at the departure end (variation 14E). At 120 knots that is 1 h 17 min at the quickest height in today's winds (34,000 ft, a 42-knot tailwind), arriving about 6:28 pm PDT (01:28 UTC), after sunset at the destination. Right now HHR is VFR, wind from the west (270°) at 7 knots; BIH is VFR, wind from the southwest (230°) at 14 knots, gusting to 22. 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: 21 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 SIERRA 6E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the first 30 nm of the route.
- AIRMET TANGO 1W: moderate turbulence below 18,000 ft (due to mountain wave) up to 12,000 ft. Over the route from 20 to 99 nm out.
- AIRMET TANGO 3W: moderate turbulence below 18,000 ft (due to mountain wave) up to 15,000 ft. Over the last 79 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 HHR.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- B737 at 14,000 ft, 41 nm east, 2:54 pm PDT (21:54 UTC): moderate turbulence. 30 nm along the route, 41 nm east of the line.

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.
