If the ITT rises more slowly than normal and the gas generator turbine speed (N1) stabilizes lower than normal, should you abort the start?

Explanation:
Aborting the start in this scenario is essential due to the unusual behavior of the ITT and gas generator turbine speed (N1). When the ITT rises more slowly than expected, and N1 stabilizes at a lower than normal speed, it indicates a potential issue with the engine start process. These parameters are critical for ensuring that the engine is reaching its operational thresholds for a stable start; deviations can signal problems such as fuel flow issues, ignition failures, or compressor stalls. In aviation operations, safety protocols dictate immediate action when there are abnormal readings that can suggest an impending engine failure or malfunction. By choosing to abort the start, operators can prevent potential damage to the engine and ensure the safety of the aircraft and crew. Hence, it's essential to recognize that when faced with these specific conditions, a decision to abort the start is warranted to mitigate risk.
