This reduced visibility impairs situational awareness, making it harder to judge distances, identify other aircraft or vehicles, and accurately interpret runway markings and lighting. The 1991 LAX disaster, while not solely attributed to limited visibility, demonstrates how challenging conditions can exacerbate other contributing factors. In that incident, while visibility was not severely restricted, the prevailing lighting conditions and runway configuration played a role in the pilots’ misjudgment of their position, ultimately contributing to the collision.
The impact of limited visibility extends beyond the immediate difficulty of seeing. It also places increased cognitive demands on pilots and controllers, who must rely more heavily on instruments and communication. This heightened workload can increase stress and fatigue, potentially leading to errors. Furthermore, limited visibility necessitates slower ground speeds and increased spacing between aircraft, impacting airport capacity and efficiency. Delayed departures and arrivals can create cascading effects throughout the air traffic system. In the context of LAX, with its high traffic volume and complex runway layout, the challenges posed by limited visibility are amplified.
Mitigating the risks associated with limited visibility requires a combination of technological advancements and procedural adjustments. Advanced ground radar systems and surface movement guidance and control systems (SMGCS) provide enhanced situational awareness in low-visibility conditions. These systems track aircraft and vehicle movements on the ground, providing controllers and pilots with real-time information. Additionally, improved runway lighting and signage enhance visibility and aid in navigation. Strict adherence to low-visibility procedures, including reduced ground speeds and increased separation between aircraft, are crucial. Ongoing training for pilots and controllers emphasizes safe operation in challenging visibility conditions. These combined efforts aim to minimize the impact of limited visibility and maintain safe and efficient operations even in adverse weather.

This incident underscores the critical importance of clear communication, proper training, and adherence to established procedures.
Several types of human error can contribute to runway disasters. Cognitive errors, such as misinterpreting information or making incorrect assumptions, can lead to miscommunication and flawed decision-making. For instance, a pilot misreading runway signage or a controller misidentifying an aircraft on radar can have devastating consequences. Perceptual errors, stemming from limitations in human perception, particularly in challenging visibility conditions, can also contribute to incidents. A pilot misjudging distance or speed in fog, or a ground crew misinterpreting hand signals, can lead to dangerous situations. Furthermore, skill-based errors, deviations from established procedures due to inadequate training or complacency, can compromise safety. A pilot failing to execute a proper go-around procedure or a controller neglecting to follow established communication protocols can create significant risks.
