Question 94Gas Turbine - 1st Asst/Chief

The correct answer is D) All of the above. When a gas turbine engine stalls while underway, the most likely indications are: 1) Combustor temperature increases 2) A loud bang is heard 3) The engine fails to accelerate An engine stall occurs when the airflow through the engine becomes disrupted, leading to a loss of thrust. This results in the above three symptoms - the increased combustor temperature, the loud bang from the stall, and the inability of the engine to accelerate normally. All three of these indications would be present during a gas turbine engine stall situation, making D) the correct choice. The other answer choices (A, B, C) are incorrect because they only describe one or two of the symptoms, rather than the full set of indications that would be observed during a gas turbine engine stall.
