Hartsfield/Jackson Atlanta International to Louis Armstrong New Orleans International ATL → MSY

369 nautical miles (425 statute miles) southwest on a straight line, true course 235°, about 240° magnetic at the departure end (variation 5W). At 120 knots that is 2 h 50 min at the quickest height in today's winds (39,000 ft, a 10-knot tailwind), arriving about 12:58 am CDT (05:58 UTC), after sunset at the destination. Right now ATL is VFR, wind from the west-northwest (300°) at 8 knots; MSY is VFR, wind from the south (190°) 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: 7,987 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

AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Near the route, at the departure end.

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 ATL.

Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

CRJ9 at 32,000 ft, 5 nm northeast, 10:00 pm EDT (02:00 UTC): moderate chop turbulence, remarks: ZTLFD-22. 40 nm along the route, 5 nm northeast 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 5 forecast points nearest it (ATL, CSG, MGM, MOB, MSY). 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.

No temporary flight restriction on or near this route right now.

Daylight

Sunset at ATL 7:07 pm EDT (23:07 UTC), at MSY 6:33 pm CDT (23:33 UTC) (civil twilight ends 6:57 pm CDT (23:57 UTC)). At 120 knots the arrival at MSY is before sunrise there (7:00 am CDT (12:00 UTC)).

Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
