On a gas turbine engine, a high outside air temperature can cause high turbine inlet temperature, low mass/weight of airflow through the turbine, and which of the following conditions?

Correct Answer: Option C — A requirement for more energy to achieve adequate compression

High ambient air temperatures decrease air density, reducing the mass flow through the compressor. To maintain a constant power output under these conditions, the engine requires more energy for compression and higher fuel flow to compensate for the reduced air mass, which can lead to increased turbine inlet temperatures.
