GEnx EMU Program Issue•Controls has been requested to look at
reducing unit cost of EMU
•Meggitt to Provide GE with a ROM estimate for the following 2 options, considering:> Development Costs> Recurring Cost> Schedule for Implementation> Weight
•GE is Open to any other suggestions not contained herein, which may additionally reduce EMU cost.
•ROM Estimate due Friday May 30th or sooner

3GE Aviation
EMU Lite Requirements• Unit cost is primary driver; weight reduction is desirable• Provide the following functions
> A/C AVM> Engine trim balance> Traditional (T/O, climb, cruise) ACARS reports> Engine position> Maintenance logic (for AVM system)> A/C data load> Minimal memory to perform these functions> HSESB data bus for ECU to EMU communications
• Will not provide the following functions> IE
– Sub-system or gas path models– Summary and event reports; full flight data– WGL communications– Enhanced ACARS
> Spare sensors> User modifiable software> CAN data bus

Option 1 – Minimize Development Cost•Maintain Current Hardware Architecture•Remove Spare Interfaces & Bulk Memory
> Eliminate J21 spare interface connector– Depopulate input circuits where possible, maintaining a stable
termination impedance– New End Cap, with J21 eliminated
> Reduce CPU1 Memory to: 4M bytes Program, 1M byte RAM, 4M byte NVM Current spec (6M bytes Program, 4M bytes RAM, 88M bytes NVM)
> Reduce CPU2 Memory to: 4M bytes Program, 8M byte RAM, 32M byte NVM Current spec (14M bytes Program, 44M bytes RAM, 368M bytes NVM)
•Assumptions:> No Impact to Cert Tests Planned for Cast Chassis> Any applicable EMI Test will be conducted by GE> Connectors & Mounting feet locations unchanged

Option 2 – Minimize EMU Functionality• Eliminate CPU2 and all associated circuitry• Reduce CPU1 Memory to:
– 4M bytes Program, 1M byte RAM, 4M byte NVM– Current spec (6M bytes Program, 4M bytes RAM, 88M bytes NVM)
• Remove Spare Interfaces> Eliminate J21 spare interface connector
– Depopulate input circuits where possible, maintaining a stable termination impedance
– New Chassis End Cap with J21 eliminated
• Re-Layout CPM module, to reduce EMU chassis size if possible• Consider smaller power supply if applicable• Consider a lower cost operating system software package to replace
GHS• Assumptions:
> For Option 2 - GE will purchase units to retrofit the field, so as to maintain a single software configuration.
> Entire Unit to be design assurance level C: > Requires New Vibration Cert Test, All Applicable EMI tests will be
performed by GE> Connector locations unchanged
