Long Beach (Daugherty Field) to Grant County International LGB → MWH

806 nautical miles (927 statute miles) north on a straight line, true course 357°, about 343° magnetic at the departure end (variation 14E). At 120 knots that is 5 h 56 min at the quickest height in today's winds (39,000 ft, a 16-knot tailwind), arriving about 10:27 pm PDT (05:27 UTC), after sunset at the destination. Right now LGB is VFR, wind from the southwest (220°) at 8 knots; MWH is VFR, wind from the northeast (050°) at 17 knots, gusting to 24. 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: 2 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 50 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 109 nm out.
AIRMET TANGO 3W: moderate turbulence below 18,000 ft (due to mountain wave) up to 15,000 ft. Over the route from 129 to 298 nm out.
AIRMET ZULU 3C: moderate icing up to 22,000 ft. Over the route from 408 to 468 nm out.
AIRMET ZULU 2C: moderate icing up to 14,000 ft. Over the last 179 nm of the route.
AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 637 to 716 nm out.

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 LGB.

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 7 forecast points nearest it (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.
