What is indicated by a "hung" start in a turbine engine?

The engine burns excess fuel
The engine fails to ignite
The engine fails to reach idle RPM
The engine produces unusual noises

The correct answer is: The engine fails to reach idle RPM

A "hung" start in a turbine engine refers to a situation where the engine starts but does not accelerate to its normal idle RPM. During the starting sequence, the engine must reach a certain RPM to stabilize and continue functioning properly. If it stalls or fails to reach this idle speed, it indicates that there is an issue that prevents it from achieving operational readiness. This could result from various factors, such as insufficient fuel flow, mechanical issues, or problems with the ignition system. A hung start is particularly concerning because it can lead to additional problems if the pilot attempts to continue the starting process without addressing the underlying issue, potentially leading to a failed start situation. Understanding this condition is vital for safe engine operation and effective troubleshooting during flight operations.
