Portland International to Mahlon Sweet Field PDX → EUG
92 nautical miles (106 statute miles) south on a straight line, true course 197°, about 181° magnetic at the departure end (variation 16E). At 120 knots that is 28 min at the quickest height in today's winds (24,000 ft, a 80-knot tailwind), arriving about 8:08 pm PDT (03:08 UTC), after sunset at the destination. Right now PDX is VFR, wind from the east (100°) at 7 knots; EUG is VFR, wind from the north-northwest (340°) at 6 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: 2,338 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 whole 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 PDX.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- EPIC at 31,000 ft, 49 nm northwest, 6:38 pm PDT (01:38 UTC): moderate turbulence from 30,000 ft to 31,000 ft, remarks: zse. At the departure end, 49 nm northwest of the line.

Winds aloft along the route, and the time en route the forecast for use 02:00–09:00 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 1 forecast point nearest it (PDX). 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.
