Why is it important to write down the maximum EGT during engine start?

Documenting the maximum Exhaust Gas Temperature (EGT) during engine start is crucial because it assists maintenance personnel in assessing the health and condition of the engine. High EGT values can indicate that the engine is operating outside its recommended parameters, which may necessitate further inspections or might signal that certain components are approaching failure. By having a recorded maximum EGT, maintenance teams can make informed decisions regarding the need for inspections, overhauls, or adjustments to ensure the ongoing reliability and safety of the engine. This data is essential for the effective maintenance management of engines, linking operational performance to necessary servicing actions.
