George Bush Intcntl/Houston Airport to Portland International Jetport IAH → PWM

1,447 nautical miles (1,665 statute miles) northeast on a straight line, true course 049°, about 046° magnetic at the departure end (variation 3E). At 120 knots that is 10 h 07 min at the quickest height in today's winds (34,000 ft, a 23-knot tailwind), arriving about 11:20 am EDT (15:20 UTC). Right now IAH is VFR, wind calm; PWM is marginal VFR, wind from the north-northeast (020°) at 3 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: 25 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 E19E: thunderstorms (a convective SIGMET) up to 43,000 ft, moving from the southwest at 20 knots, until 1:55 am CDT (06:55 UTC). Over the route from 958 to 978 nm out.

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 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 17 forecast points nearest it (HOU, LCH, SHV, JAN, MEM, HSV, BNA, TYS, LOU, CRW, EKN, AGC, PSB, AVP, ALB, BOS, PWM). 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.
