Clarence E Page Municipal to Boeing Fld/King County International RCE → BFI

1,308 nautical miles (1,505 statute miles) northwest on a straight line, true course 311°, about 304° magnetic at the departure end (variation 7E). At 120 knots that is 10 h 28 min at the quickest height in today's winds (8,500 ft, a 5-knot tailwind), arriving about 2:58 am PDT (09:58 UTC), after sunset at the destination. Right now RCE is VFR, wind from the south (180°) at 19 knots, gusting to 28; BFI is VFR, wind variable at 4 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: 33 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

SIGMET W67W: thunderstorms (a convective SIGMET) up to 28,000 ft, moving from the south at 40 knots, until 7:55 pm CDT (00:55 UTC). Near the route, 819 nm along the route.

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 13 forecast points nearest it (OKC, GAG, GCK, GLD, DEN, RKS, LND, PIH, DLN, BOI, LWS, YKM, SEA). 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.
