What is the correct range for EGT during normal APU starting conditions?

The correct range for exhaust gas temperature (EGT) during normal Auxiliary Power Unit (APU) starting conditions is from 0°C to 715°C. This range is significant as it indicates the temperature limits within which the APU can start safely without causing damage to its components. The APU generates power and provides pneumatic pressure for starting engines, so monitoring the EGT is crucial for ensuring optimal performance and preventing overheating.

When the APU starts, the engine goes through various temperature levels, and it's essential to have an upper limit to avoid turbine damage or failure due to excessive heat. The upper limit of 715°C reflects the technical engineering data provided for the APU, which ensures that operations are carried out within safe parameters, enabling efficient function while minimizing the risk of failure.
