What indications are shown on the engine display in the Pilatus PC-12 NG?

The correct choice identifies the primary parameters displayed on the engine display of the Pilatus PC-12 NG, which includes Torque, Interstage Turbine Temperature (ITT), RPM (Revolutions Per Minute), and fuel flow.

Torque is crucial for understanding how much power the engine is producing and is a key indicator of engine performance. ITT provides information on the temperature of the gases after they exit the turbine, which is critical for monitoring engine health and preventing overheating. RPM offers insights into the engine's operating speed, allowing pilots to manage power effectively. Finally, fuel flow is vital for fuel management, helping pilots assess their fuel consumption and endurance during the flight.

Understanding these parameters allows pilots to make informed decisions during various phases of the flight, ensuring safe and efficient operation of the aircraft.
