George Bush Intcntl/Houston Airport to Portsmouth International AT Pease IAH → PSM

1,412 nautical miles (1,625 statute miles) northeast on a straight line, true course 049°, about 046° magnetic at the departure end (variation 3E). At 120 knots that is 9 h 07 min at the quickest height in today's winds (39,000 ft, a 35-knot tailwind), arriving about 6:12 am EDT (10:12 UTC), after sunset at the destination. Right now IAH is VFR, wind from the southeast (130°) at 10 knots; PSM is VFR, wind from the south (170°) 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: 5 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 6W: moderate turbulence above 18,000 ft from 28,000 ft to 40,000 ft. Over the route from 487 to 597 nm out.
AIRMET SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 616 to 915 nm out.
AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 656 to 1243 nm out.
AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 21,000 ft to 33,000 ft. Over the last 477 nm of the route.
AIRMET SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 964 to 1352 nm out.
AIRMET TANGO 2W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 1034 to 1213 nm out.
AIRMET TANGO 2W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the last 368 nm of the route.
AIRMET ZULU 1C: moderate icing up to 24,000 ft. Over the last 159 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 IAH.

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 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 16 forecast points nearest it (HOU, LCH, SHV, JAN, MEM, HSV, BNA, TYS, TRI, CRW, EKN, PSB, AVP, ALB, BDL, BOS). 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.
