Why do memory items need to be performed when FADEC aborts a start?

Memory items need to be performed when FADEC aborts a start primarily because fuel continues to flow while the starter valve is open. This situation poses a risk of an uncontained engine start, which can lead to hazardous conditions such as a fire or an engine failure. The FADEC (Full Authority Digital Engine Control) system is designed to manage the engine’s start sequence efficiently, but if an abort occurs, it is crucial for the flight crew to act rapidly to ensure that fuel flow is stopped and that the starter is disengaged according to the established procedures.

Performing the appropriate memory items allows the crew to effectively respond to the situation by ensuring that all necessary actions are taken in a timely manner, which helps maintain safety and control of the engine. Understanding this element of emergency protocol is vital for effective aircraft operation and safety management.
