About Louis Armstrong New Orleans International Airport
Overview
Louis Armstrong New Orleans International Airport (KMSY) serves the greater New Orleans metropolitan area as a critical transportation hub. Located at 29.993401, -90.258003, the airport sits at a low elevation of 4 feet mean sea level, characteristic of the Gulf Coast region. The airport features three runways, with the longest being Runway 11/29 at 10,104 feet of pavement.
Flying Conditions
New Orleans' coastal location creates dynamic weather conditions with potential for rapid changes, particularly during hurricane season. The airport's low elevation makes it susceptible to fog, especially during early morning and transitional seasonal periods. Multiple runways provide flexible wind coverage, with Runway 11/29's substantial length offering significant operational advantages.
Notable Features
The airport's three runways provide multiple approach and departure options, with surface types consisting of asphalt (ASP) and Portland Emerging Material (PEM) pavements. Runway 11/29's extended 10,104-foot length accommodates a wide range of aircraft types and operational requirements. The airport's geographic positioning near the Mississippi River delta presents unique navigational considerations for pilots.
Approach Considerations
Pilots should anticipate variable wind conditions due to the coastal environment, with runways 02/20, 06/24, and 11/29 offering different wind alignment options. Runway 11/29's longer configuration makes it preferable for larger aircraft and provides more landing flexibility. The airport's low elevation requires standard sea-level approach considerations, with potential for reduced visibility during seasonal weather transitions.
