While underway on a ship with gas turbine engines, the most likely indication of an engine stall is _________.

Correct Answer: Option D — All of the above

A gas turbine stall is characterized by a disruption in airflow, leading to a rapid rise in combustor temperature, audible bangs from flow reversal, and an inability of the engine to accelerate. These symptoms indicate a loss of compressor stability, requiring immediate operator intervention to prevent severe thermal damage.
