A Step Ahead to the IMA2G

Technical information

From IMA1G to IMA2G

Early avionics were implemented as a federated architecture, in which each aircraft function (e.g. flight control, flight management, navigation, or systems control) was implemented using dedicated hardware and software.

The IMA concept was introduced to solve these problems like large size and complexity of the federated architecture, large cost of overall avionics platform while reducing the efficiency of airline maintenance operations.

The Federated Architecture Concept vs. the IMA1G concept


From IMA1G to IMA2G

Fifteen years after the first definition of its concepts, the IMA solution has been chosen in most of the new avionic developments for large Aircraft (A380, A350, B777, B787) to military Aircraft (A400M) and regional category (ATR, RRJ).

IMA based avionics is the best environment for competitive solutions for any future avionics platform.

While modules, building blocks and technical principles to achieve these KCCs have been successfully developed in SCARLETT as the DME concept, there is a need to define the overarching platform organisation and implementation of those elements. This is one of the main objectives of ASHLEY and will provide a key element in the deployment of IMA2G.

Progress Beyond the State Of The Art

The current state of the art is principally made by the outcomes of the SCARLETT EC funded FP7 Level 2 project and other national projects, including IDEE5 (FR) and LUFO (DE) by proposing and evaluating a set of building blocks of the DME concept.

The following sections detail for each theme the expected achievements of ASHLEY and the link with the results from previous projects.

    • The wide application of IMA components throughout multiple programs is an important objective for large industrialization of IMA.
    • Modularity is understood as an architecture concept where you can build architecture by adding or removing components according to the hosted systems requirements, which can change during development.
    • Integration of more than one system function in one component requires guaranteed segregation between the hosting partitions.
    • Achieve a more standardized means of designing and configuring avionics (multi-domains) functions through a coherent, platform oriented tool chain.

Address certification issues for new components and services, included but not limited to platform architecture, data management, cabinet, database server, and smart sensors.
