During a manual start, ____ is not available.

In a manual start, the automatic abort feature is not available. During a manual engine start, the pilot must actively monitor the start process and manually intervene if necessary. This means that systems designed to autonomously monitor the start sequence and abort if abnormal conditions are detected are not engaged in manual mode.

Automatic abort functions are part of automated systems designed to enhance safety and reduce pilot workload during engine starts, particularly in normal operations. However, when the start is performed manually, the pilot assumes full responsibility for monitoring the parameters and must make decisions without the advantage of automatic safeguards.

In contrast, dual ignition is available during a manual start, allowing the use of both igniters to assist with starting the engine. Similarly, ECAM (Electronic Centralized Aircraft Monitor) continues to function and provide relevant data to the pilot, helping assist in managing the manual start operation. FADEC (Full Authority Digital Engine Control) monitoring is also in place to keep track of engine parameters, even though the start method is manual. Thus, it is the absence of the automatic abort function that clearly distinguishes the manual start process from a more automated one.
