From the gas turbine engine indicators, which subsystem can be monitored?

• A. FADEC
• B. ECU
• C. The RIMMS
• D. Hydraulic system

Answer: (C)

Engine indicators show the status and health of subsystems that feed data to the cockpit displays. The subsystem designed to be monitored by these indicators is the Remote Indicating and Monitoring System. RIMMS collects signals from engine sensors and presents them in a way that lets the crew observe parameters and alarms in real time. FADEC or ECU are control units that manage engine operation; they generate commands and monitor internal parameters, but they aren’t the subsystems whose status is read directly by the engine indicators. The hydraulic system has its own indicators and isn’t part of the engine-indicator monitoring network. So, the subsystem monitored by the engine indicators is the RIMMS.
