When a flame detector receives a signal, where does the flame detection system send the signal?

The correct response indicates that when a flame detector receives a signal, it sends that signal to the SCU (Start Control Unit) and the PACC (Power Augmentation Control Computer).

The flame detection system's primary role is to ensure safety by monitoring for the presence of a flame in the combustor. If the flame detector senses an active flame, it relays that information to the SCU and PACC. This allows these components to manage the engine's operating conditions effectively, ensuring optimal performance and safety.

The SCU uses the flame signal for starting and controlling the gas turbine, and the PACC can modify fuel flow and air management to maintain flame stability. This integration of the flame detection signal supports the operational integrity of the gas turbine and helps prevent potentially hazardous conditions.
