Simultaneous Landings on Multiple Runways at Los Angeles International Airport LAX

Los Angeles International Airport (LAX) is one of the busiest airports in the world, handling over 50,000 operations per year. Despite its complexity, it is possible for aircraft to land on two different runways simultaneously. This article explores the conditions, procedures, and fascinating scenarios that make this possible at such a major hub.

Conditions for Simultaneous Landings

The primary factors allowing for simultaneous landings are weather conditions and the use of specific separation rules. VMC (Visual Meteorological Conditions) are ideal for these scenarios, while IMC (Instrument Meteorological Conditions) add a layer of complexity.

Visual Conditions (VMC)

When visibility is clear and weather permits, control towers can facilitate simultaneous independent approaches to one runway in the north complex and one runway in the south complex. This phenomenon, known as inboarding, can be visually stunning, with multiple large aircraft making their final approaches virtually side-by-side. Pilots in the north complex can land on Runways 24R and 24L, while those in the south complex can land on Runways 21R and 21L.

Instrument Conditions (IMC)

Under IMC, simultaneous independent approaches to two runways are possible but require the involvement of two additional controllers to monitor final stages, adding an extra layer of complexity.

Procedure for Simultaneous Landings

Typically, visual approaches are conducted during clear VMC conditions, utilizing both the north and south complexes for simultaneous landings. However, when necessary, controllers can use a combination of controlled procedures to ensure safe landings. For instance, limited control deflections in Visual Approach (VA) mode have been known to facilitate such scenarios, but it is critical to maintain aircraft separation at all times.

Control Deflections

Control deflections involve slight adjustments in flight paths to ensure safe distances between aircraft. Pilots and controllers must work in tandem to execute these maneuvers, often involving coordinated maneuvers and coordinated adjustments to maintain separation orders.

Real-World Examples

Los Angeles International Airport has hosted some of the most impressive simultaneous landing scenarios. For example, on particularly busy days, the air traffic control team has handled over 177 arrivals in an hour, showcasing the complexity and efficiency of the system. One moment I witnessed, a controller named Doug managed to direct over 90 planes to the north complex in one hour while the south complex was closed, a truly remarkable feat.

Conclusion

Simultaneous landings on multiple runways at Los Angeles International Airport are a testament to the skill, coordination, and efficiency of air traffic control. While weather and procedures play crucial roles, the human element remains key, ensuring that even the most complex scenarios can be managed with precision and safety.
