How many computers are necessary to activate the shaker?

The shaker is an important component in aircraft systems designed to provide tactile feedback during critical situations, such as stall warnings. The activation of the shaker typically involves input from a single monitoring system that detects parameters indicative of a stall condition.

In many aircraft systems, the activation mechanism for the shaker is designed to be straightforward and efficient, often relying on one dedicated computer or system that monitors flight data and conditions. This allows for quicker responses and minimizes the complexity of the system, which is crucial in critical flight situations where timely alerts are necessary.

Choices that suggest two, three, or four computers introduce unnecessary complexity into the activation process. While redundancy is a critical principle in avionics to ensure safety and reliability, the specific function of activating the shaker can typically and effectively be managed by one computer system. This design approach ensures that vital alerts can be issued without potential delays that could arise from multiple systems needing to coordinate the same action.
