Guam International to Henderson Executive GUM → HND
5,406 nautical miles (6,221 statute miles) northeast on a straight line, true course 053°, about 051° magnetic at the departure end (variation 2E). At 120 knots that is 40 h 57 min at the quickest height in today's winds (39,000 ft, a 12-knot tailwind), arriving about 12:41 pm PDT (19:41 UTC). 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: 714 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 route from 4886 to 5076 nm out.
- AIRMET TANGO 2W: strong surface winds (30 knots or more) (due to sustained surface winds greater than 30 knots). Over the route from 4886 to 4956 nm out.
- AIRMET TANGO 3W: moderate turbulence below 18,000 ft (due to mountain wave) up to 15,000 ft. Over the route from 5216 to 5296 nm out.
- AIRMET TANGO 1W: moderate turbulence below 18,000 ft (due to mountain wave) up to 12,000 ft. Over the route from 5306 to 5376 nm out.
- AIRMET ZULU 3C: moderate icing up to 22,000 ft. Over the last 80 nm of the route.
- AIRMET TANGO 4W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the last 10 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 GUM.

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 9 forecast points nearest it (AST, OTH, CAR, OTH, FOT, SFO, FAT, BIH, LAS). A plus sign is a headwind, a minus sign a tailwind.

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.
