How to Maintain Proper Exhaust Gas Temperature (EGT) in Aviation APUs

The Importance of Monitoring Exhaust Gas Temperature (EGT) in Aviation APUs

Exhaust Gas Temperature (EGT) is a crucial parameter to monitor in aviation Auxiliary Power Units (APUs) due to its direct impact on the performance and safety of the aircraft. APUs are used to provide electrical power, air conditioning, and other essential functions when the main engines are not running. Maintaining the EGT within specified limits is vital to ensure the APU operates efficiently and safely.

High EGT levels can indicate potential issues such as fuel combustion problems, air leaks, or other malfunctions within the APU. Monitoring the EGT allows operators to detect abnormalities early and take corrective actions to prevent further damage or safety hazards. On the other hand, excessively low EGT levels can also be problematic, leading to incomplete combustion and inefficient APU operation.

By continuously monitoring and adjusting the EGT, aviation professionals can optimize the performance of the APU, prevent engine damage, and ensure the safety of the aircraft and its occupants. Proper EGT management is essential for the longevity and reliability of aviation APUs.
