Why IMA?

Since the A300

Increasing number of software controlled systems

-New functionality for performance

Flight management systems

Fuel management systems

-New functionality for improved safety

Flight envelope protection

Ground proximity warning

Traffic collision avoidance

-New functionality for improved maintenance

Aircraft condition monitoring

-New functionality for improved passenger comfort

Cabin environment control

Why IMA?

The Indirect Consequences

Every system = 1 or more computers / controllers

Every aircraft type = new computers

Every computer =

-Airframer development and management costs

Part number costs

Documentation

More wires

More power

More sources of unreliability

Increased obsolescence risk

-Airline impact

Spares

Tooling

Increased fault finding

Why IMA? - Traditional LRU

This implies that quantities of maintenance spares be stored for each fleet at different places. During the aircraft life cycle, the cost of modifications, including parts obsolescence mitigation and functional upgrades, becomes even more significant for the airlines.

Why IMA? - Traditional LRU

Each computer type is

uniquely designed for the system and aircraft

Application software

e.g. fuel control

Hardware PCBs

Operating System

Manufactured by

system supplier

Digital and single wire control

Information to other computers

Dedicated wiring for

each connection

Why IMA?

The response

Integrated Modular Avionics

-Concept -Not a specific set of technologies or components

Integration =

-Multiple systems applications executed on the same computer -Data communications integrated onto a high speed multiplexed network

Modularity =

-A set of standard non system specific computers -Computers that can be configured to provide part of their resources to a particular system application

What is A380 IMA?

Since mid 80s the former Airbus partners have done research on IMA for their systems (PACTS, IDEE3, NEVADA, PAMELA,

VICTORIA)

- With the objective to merge different system design approaches and different procurement approaches Closed loop control systems, data management and processing systems

Safety critical and non safety critical

Software only functions to full multi-domain systems like fuel Complete design in house, integration of components to fully outsourced

Therefore the IMA solution had to:

- Be suitable for different types of systems (I/O needs / Performances /

Safety )

- Be suitable for a large number of systems and their suppliers to allow real competition - Compartmentalised to allow parallel developments to be managed
