t.IMA top level objectives for the A380

• Reduce recurrent costs by reducing the amount of on-board electronics

• Reduce avionics development costs for the Airframerand for Equipment suppliers

• Reduce airlines maintenance costs

• All this whilst guaranteeing Outstanding safety and availability for such a large aircraft Increased performance and growth capability margins Keeping independence between function providers

• IMA solutions preparation was intensively performed from1994 to 2001 (A380 launch) through large researchprojects with avionics suppliersAssessment of System ArchitecturesEvaluation of TechnologiesExercise the IMA industrial processLeading to avionics demonstrators to validate choices and

allow suppliers to go towards maturity

So the IMA solutions have already been experienced by theindustrial actors even before A380 launching

t.IMA Solutions for the A380

• Reduce recurrent costs :Reducing the amount of embedded electronics hardware by sharing

HW & SW resources between avionics systems Multiplexed communication: AFDX & CAN Computers host several avionics functions

•Reduce avionics development costs :Only 2 “Module Suppliers” cooperating around sub assemblies to

develop and supply all the IMA “bare modules” (hardware andoperating software, no systems application)

• Reduce airlines maintenance costsLess electronics => high availabilityLess equipment part numbers => less spare parts

t.IMA Process and Responsibilities for CPIOM

• Basic PrinciplesA Module supplier

– Develops Bare Modules including an operating system with astandardised interface (API) users, and strong segregation mechanisms

– Develops associated toolset for users• OS simulators,• Configuration tools and Verification tools for users

– Is responsible for qualification activities at bare module level

Function Suppliers– Develop avionics functions– Integrate and verify and qualify their functions on IMA modules

Airbus– Develops configuration tables which create the “link” between Module

Resources and information, and avionics functions
