Hector International to Frederick W Smith Intl/Memphis Airport FAR → MEM

777 nautical miles (894 statute miles) southeast on a straight line, true course 154°, about 150° magnetic at the departure end (variation 4E). At 120 knots that is 4 h 59 min at the quickest height in today's winds (34,000 ft, a 36-knot tailwind), arriving about 12:41 pm CDT (17:41 UTC). Right now FAR is IFR, wind from the northwest (320°) at 9 knots; MEM is VFR, wind from the south-southwest (210°) 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: 450 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 C33C: thunderstorms (a convective SIGMET) up to 36,000 ft, moving from the southwest at 35 knots, until 8:55 am CDT (13:55 UTC). Over the route from 359 to 398 nm out.

AIRMET SIERRA 4E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the first 100 nm of the route.
AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 24,000 ft to 36,000 ft. Over the first 189 nm of the route.
AIRMET TANGO 1W: 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 468 to 627 nm out.

Turbulence AIRMET in force: moderate turbulence from 24,000 ft to 36,000 ft, over the first 189 nm of the route. AIRMET in force: 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 468 to 627 nm out. 1 pilot report of turbulence near the line in the last three hours: light chop turbulence, at 33,000 ft, 39 nm east, 7:01 am CDT (12:01 UTC). The government's turbulence forecast map ↗

Icing No icing warning in force along the route. A pilot reported no icing, at 2,600 ft, 4 nm east, 7:28 am CDT (12:28 UTC). The freezing level is about 14,000 ft (from the winds-aloft temperatures), so icing is possible in cloud above that. 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 FAR.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 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 7 forecast points nearest it (AXN, FSD, MCW, DSM, COU, CGI, MEM). 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.

From the FAA's notice service (NOTAMs), the site's copy refreshed every few minutes; last checked 1 minutes ago. 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. Times are local to the field. This is for planning; the legal briefing comes from Flight Service or the FAA's own tools.

Daylight

Sunset at FAR 6:44 pm CDT (23:44 UTC), at MEM 6:27 pm CDT (23:27 UTC) (civil twilight ends 6:53 pm CDT (23:53 UTC)).

Each restriction opens the FAA's own page with the exact area, heights and times.

The wind over the route live wind map, from Windy.com · drag the time bar for the coming hours; the level menu changes the height

Colours show wind speed, the moving lines its direction, at the surface unless you pick a height. Map and forecast by Windy.com; a second opinion beside the government's winds-aloft table above.
