Electronic engine controller

摘要

A controller (18) is provided in which an independent protection controller (38) is provided in a casing (8), which casing (8) is disposed within the casing (4) for the main controller (18), such that the protection controller (38) is provided as a box within a box. This allows the casing (4) for the main controller to provide extra protection to the protection controller (38) against mechanical stress and damage. The independent protection module is directly connected to a pilot operated "shut down" demand and in response to such a demand assumes authority to shut the engine down.
