What indicators must be monitored for engine performance?

Monitoring engine performance is critical for ensuring safe and efficient operation of the aircraft. The correct answer includes N1, N2, EGT, and fuel flow, which are essential indicators used to assess engine health and performance.

N1 refers to the speed of the low-pressure turbine, while N2 indicates the speed of the high-pressure turbine. Both N1 and N2 are crucial for understanding how the engine is operating, as they provide insights into the engine’s thrust capabilities and efficiency.

EGT, or Exhaust Gas Temperature, is another vital parameter that reflects the temperature of the gases exiting the engine. This measurement is important because it helps identify if the engine is operating within its designed thermal limits. High EGT readings can indicate potential engine problems or inefficiencies.

Fuel flow is also fundamental in monitoring engine performance since it indicates the rate at which fuel is being consumed by the engine. This parameter can help in assessing the efficiency of the engine and its performance during various flight phases.

Together, these indicators provide a comprehensive view of engine performance, allowing pilots to make informed decisions regarding engine management and overall flight safety.
