How is a pilot informed when an anti-skid system switches to a manual braking system?

A pilot is informed when an anti-skid system transitions to a manual braking system primarily through a warning light. This indicator alerts the pilot of the change in the braking system's functionality, allowing them to be aware that the automated anti-skid system is no longer operational.

The reason this method is used is that visual alerts can quickly catch a pilot's attention, and they can assess the situation without needing to divert their attention away from the flight's critical tasks. While other methods, such as sounds or vibrations, can also provide notifications, warning lights are specifically designed for clarity and immediate comprehensibility, which is vital during flight operations. Hence, pilots depend on visual cues to make informed decisions regarding the aircraft's braking performance and respond appropriately to any mechanical alterations.
