What information does the Primary Engine Data Display (PEDD) provide?

• A. Altitude and airspeed
• B. Torque, N1, Np, ITT, IOAT
• C. Fuel flow and engine temperature
• D. Cabin pressure and outside air temperature

Answer: (B)

The Primary Engine Data Display (PEDD) is specifically designed to give crucial information regarding engine performance. The correct choice highlights key metrics such as torque, N1 (the first fan rotor speed), Np (propeller speed), ITT (Interstage Turbine Temperature), and IOAT (Inlet Outside Air Temperature), which are vital for monitoring the engine's operational status and performance in real-time. These parameters allow the crew to assess how efficiently the engine is functioning and whether it is operating within safe limits. Monitoring these values is essential for aircraft safety, performance management, and ensuring proper engine health throughout the flight. Other options provide relevant data that pertain to different aspects of flight operations, but they do not specifically relate to the primary information provided by the PEDD.
