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
IMA = Integrated Modular Avionics

Increasing the set of functions hosted by the IMA platform reduces
risk on maturity: the development effort for core electronics (HW / OS)
is communalised

cycle
Increase
operational
reliability
Scalability to
various aircraft
types
1 – Provide a
scalable solution
2 – Define minimal set of modules
3 – Increase number of supported
function
4 – Develop new standards to
support 2nd generation IMA
Avoid
unscheduled
maintenance
5 – Provide associated process and toolset
6 – Demonstrate fault
tolerance
-- and reconfiguration
Reduce Set of
Part Numbers
Reduce cost of
spare parts
Save weight,
volume, power
consumption
IMA2G improvements
16 /
IMA1G
Is only used for selected applications
Characterized by several types of processing Modules because of Input / Output
Does authorize better reuse and less Part Numbers but not re-configurability
IMA1G+
Performance upgrading to sustain more functions
Upgrade Operating System with separation between Local and Global variable
Generalization of Incremental Certification
IMA2G
Will separate Input / Output from computing resource
Will bring enhanced performance enabling a greater number of applications to be
hosted on the same module
Will provide specific platform services such as reconfiguration
Will enable scalability
