What happens during a non-precision approach if the pilot is unable to establish an ACLS lock-on?

In a non-precision approach, pilots rely on visual references along with navigational aids to guide them safely to the runway. If the pilot is unable to establish an Automatic Carrier Landing System (ACLS) lock-on, it indicates that the automated system is not functioning as intended. However, this does not prevent the pilot from continuing the approach visually, assuming that visual conditions allow it.

Pilots are trained to use their judgment and visual references to execute the landing safely if the approach aids malfunction. They can visually locate the runway, approach path, and other relevant landmarks to facilitate the landing. Continuing the approach visually is a standard procedure as long as weather and visibility conditions meet the necessary requirements for visual flight. In the event of insufficient visibility, the pilot would consider other options, such as diverting to an alternate airport or holding altitude, but under good conditions, visual continuation remains an option.

This understanding is crucial for ensuring safety and operational efficiency during non-precision approaches, especially in a carrier air traffic control context where maintaining situational awareness is key.
