Can the EGT system on a turbine engine be tested without running the engine?

The EGT (Exhaust Gas Temperature) system in a turbine engine can indeed be tested without running the engine by checking the thermocouples and their associated circuits. This involves verifying that the thermocouples are functioning correctly and that their electrical connections are intact. Multimeters can be used to measure resistance and ensure continuity in the circuits, confirming that the thermocouples are in good working order.

This method is valuable because it allows for preliminary checks that can identify issues in the EGT system without the need for engine operation, therefore reducing wear and maintaining safety.

The other options typically describe scenarios that either require engine operation to directly observe measurements or are overly broad in their inspection requirements, whereas the ability to conduct tests on thermocouples and circuits independently allows for effective troubleshooting.
