Question: 1 / 400

What is the first engine instrument indication of a successful start of a turbine engine?

A rise in engine rpm

A rise in oil temperature

A rise in the exhaust gas temperature

The first engine instrument indication of a successful start of a turbine engine is a rise in the exhaust gas temperature. This is because as the engine starts, the flow of hot gases through the engine increases, causing the temperature to rise first. A rise in engine rpm (choice A) and oil temperature (choice B) will occur after a rise in exhaust gas temperature. A decrease in fuel flow (choice D) would not indicate a successful start of the engine, as the engine would not be receiving any fuel. Therefore, C is the most accurate and logical answer.
