About Louisville Muhammad Ali International Airport

Overview

Louisville Muhammad Ali International Airport serves as a major cargo and passenger hub located in Kentucky, strategically positioned near the Ohio River. As a large airport with significant infrastructure, it provides critical aviation services for the Louisville metropolitan area and regional transportation network. The airport's three substantial concrete runways enable diverse aircraft operations across multiple flight categories.

Flying Conditions

Located at 501 feet mean sea level, the airport experiences typical mid-latitude weather patterns with seasonal temperature and wind variations. Its central US location means potential encounters with frontal systems, convective activity, and moderate wind conditions across different times of year. Pilots should anticipate variable wind directions given the airport's three runway orientations which provide flexible approach and departure options.

Notable Features

The airport features three parallel runway configurations (11/29, 17L/35R, and 17R/35L) with substantial runway lengths ranging from 7,250 to 10,850 feet. This diverse runway system accommodates various aircraft types, from regional commuters to large cargo and passenger jets. The geographical positioning near Louisville provides relatively flat terrain with minimal significant elevation changes that might impact approach or departure procedures.

Approach Considerations

Runway selection will typically depend on prevailing wind conditions, with the three runway orientations offering multiple approach angles. The longest runway (17R/35L at 10,850 feet) provides maximum operational flexibility for larger aircraft and challenging meteorological conditions. Pilots should utilize standard instrument approach protocols and remain aware of potential wind shifts given the airport's multiple runway options.
