What parameters does the PEDD provide?

• A. Torque, ITT, N1, Np, IOAT
• B. Fuel flow, RPM, engine pressure, and temperature
• C. Altitude, speed, heading, and engine temperature
• D. Oil pressure, fuel levels, torque, and battery charge

Answer: (A)

The Primary Engine Data Display (PEDD) provides crucial operational parameters that are essential for monitoring the engine's performance and ensuring safe flight operations. The parameters listed in the correct answer include Torque, Interstage Turbine Temperature (ITT), N1 (the speed of the low-pressure compressor), Np (the propeller speed), and Inlet Overall Air Temperature (IOAT). These parameters are critical for pilots as they provide real-time data about the engine's condition and efficiency. For instance, monitoring ITT allows the pilot to ensure that engine temperatures remain within operational limits, which is vital for preventing overheating and potential engine failure. N1 is particularly important as it indicates the power output and performance level of the engine, while Np assesses the propeller's performance. Torque provides insights into the engine's power transmission to the propeller, ensuring optimal performance under various flight conditions. The other options provide parameters that are either unrelated to engine performance or are measured by different systems. Fuel flow, RPM, engine pressure, and temperature represent general engine performance indicators, but not specifically what the PEDD displays. Similarly, altitude, speed, heading, and engine temperature encompass broader flight data that would typically be found on a different display, not solely on the PED
