Final answer:
While you cannot measure actual exhaust gas temperature without running the engine, preliminary checks such as continuity tests on the EGT probes or wiring, and self-tests of the EGT gauge or readout system can be conducted without engine operation.
Step-by-step explanation:
The question relates to whether the Exhaust Gas Temperature (EGT) system on a turbine engine can be checked without running the engine. To answer this, the EGT system primarily measures the temperature of the gas flowing out of a turbine engine, which is a critical parameter for engine performance and health monitoring.
Without the engine running, you cannot measure the actual exhaust gas temperature, as there is no exhaust gas to measure. However, some preliminary checks can be performed on the EGT system without running the engine, such as conducting a continuity test on the EGT probes or wiring to ensure there are no open circuits or shorts. Additionally, the EGT gauge or readout can undergo a self-test if the system supports it to confirm the display and sensor connectivity are functioning correctly.
