Barter Island Airport to Point Lay Lrrs Airport BTI → PIZ
398 nautical miles (458 statute miles) west on a straight line, true course 276°, about 258° magnetic at the departure end (variation 18E). At 120 knots that is 3 h 29 min at the quickest height in today's winds (4,500 ft, a 6-knot headwind), arriving about 7:35 am AKDT (15:35 UTC), after sunset at the destination. Right now BTI is marginal VFR, wind from the north (350°) at 7 knots; PIZ is marginal VFR, wind from the north-northeast (020°) 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: 1 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
No SIGMET or AIRMET covers any part of this route right now.
Turbulence No turbulence warning in force along the route. No pilot has reported turbulence near the line in the last three hours. The government's turbulence forecast map ↗
Icing No icing warning in force along the route. No pilot has reported icing near the line in the last three hours. The freezing level is below 6,500 ft, the lowest forecast height, so any cloud could carry ice. The government's icing forecast map ↗
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 BTI.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

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 3 forecast points nearest it (BTI, BRW, LUR). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 13th at 06:00 UTC; valid on the 13th at 12:00 UTC for use 08:00 to 15:00 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.

The FAA has so far issued eFlight its test feed, which misses some notices (checked against the FAA's own search on 12 October: about a third missing at Santa Barbara and Burbank, none at Atlanta or Las Vegas); the request for the full feed is with the FAA.
