Question: 1 / 400

What is the temperature measured aft of the turbine referred to as?

Exhaust gas temperature (EGT)

The temperature measured aft of the turbine is referred to as the exhaust gas temperature (EGT). This measurement is crucial for assessing the performance and operational efficiency of the turbine engine. EGT provides valuable insights into the engine's health, indicating whether it is operating within safe temperature limits. Analyzing EGT trends can help detect potential issues, such as imbalances in fuel flow or air supply, which could lead to performance degradation or even engine failure if not addressed promptly.

Understanding EGT is vital for maintenance and operational decision-making, allowing operators to optimize fuel consumption, manage engine wear, and ensure overall safety during flight operations. Measurements are typically taken at specific locations after the turbine, where the exhaust gases exit the engine, providing a clear indication of the thermal conditions the engine experiences during operation.
