Avionics Architecture evolution – a short history

A320/340A310

In 1970’s and 1980’s, 2 major trends:

� Increase of complexity� Increase the number of equipments installed on aircraft

� Increase the number of wires to interconnect all equipments

� Higher level of requests and constraints� Time to market (including management of obsolescence)

� Safety

� Performances

� Maintenance costs

Between 1990’s and 2000’s, a new step is reached:capability to integrate several applications inside a common unit

� IMA is identified as a concept permitting to� Reduce the number of equipments installed on aircraft � Integration

� Reduce the number of types of equipments installed on aircraft � Modularity and costs

� Reduce the number of connexions � Simplicity

15 /15 / From IMA1G/IMA1G+ to IMA2G : SCARLETT Objectives

Increase operational reliability

Avoid unscheduled maintenance

Reduce Set of Part Numbers

Scalability to various aircraft

types

Reduce development

cycle

Reduce cost of spare parts

1 – Provide a scalable solution

2 – Define minimal set of modules3 – Increase number of supported

function4 – Develop new standards to

support 2 nd generation IMA

5 – Provide associated process and toolset

6 – Demonstrate fault tolerance

-- and reconfiguration

Save weight, volume, power consumption

16 /16 / IMA2G improvements

IMA1G

� Is only used for selected applications

� Characterized by several types of processing Module s because of Input / Output

� Does authorize better reuse and less Part Numbers b ut not re-configurability

IMA1G+

� Performance upgrading to sustain more functions

� Upgrade Operating System with separation between Lo cal and Global variable

� Generalization of Incremental Certification

IMA2G

� Will separate Input / Output from computing resourc e

� Will bring enhanced performance enabling a greater number of applications to be hosted on the same module

� Will provide specific platform services such as rec onfiguration

� Will enable scalability
