Alternate Engine Data Display (AEDD)

The alternate engine data display (AEDD) provides each cockpit with backup visual indication of engine operations.

The display provides some of the same information as the PEDD, however unlike PEDD and with the exception of torque, the data for AEDD is not processed by PMU. Torque is first determined by PMU and then sent to EDM for display.

Information provided on the AEDD includes;

• Raw Inter-Turbine Temperature (RITT)
• Torque
• Gas generator speed (N1)
• Cockpit pressure altitude (Not functional in current build)
• Cockpit differential pressure (Not functional in current build)
• Fuel flow
• Fuel quantity

The fuel quantity gauge receives information from fuel probes to generate a visual display of amount of fuel (in pounds) residing in wing tanks and collector tank.

The fuel flow gauge receives information from the fuel flow transmitter and shows the rate of fuel consumption in pounds per hour.
