Concept of adaptive avionics platform as self-configuring avionics.
during their Ph.D. time. They published partial aspects of
the AAP previously [6], [7], [8], [9], [10].
The remainder of this paper is organized as follows.
Section "STATE-OF-THE-ART AND SCIENTIFIC
CONTRIBUTION" details the current state-of-the-art of
standardized avionics and adaptivity. Section "ADAPTIVE
AVIONICS PLATFORM CONCEPT" introduces the
AAP in terms of software structure, logics, and behavior.
In Section "VERIFICATION AS AN ADAPTIVE CABIN
MANAGEMENT SYSTEM," an ACMS is presented, realizing the AAP in real hardware. Section "VERIFICATION
OF THE ADAPTIVE PLATFORM CONCEPT" reports the
results of the verification of the ACMS in a lab demonstration. This paper closes with a discussion of the results
obtained in section "DISCUSSION" and a conclusion in
section "CONCLUSION."
STATE-OF-THE-ART AND SCIENTIFIC CONTRIBUTION
The following text summarizes the current technology
of IMA and CMS as well as their challenges. This is
MARCH 2019
followed by a summary of the state-of-the-art research in
automated configuration and the new contribution of the
AAP concept.
INTEGRATED MODULAR AVIONICS
IMA is the concept of hardware sharing and standardization in the safety-critical avionics domain [11].
All system functions run as applications on a standardized operating system. The safety-critical (DALA) and no-safety-effect (DAL-E) function share the
same hardware since they are strictly segregated in
space and time. Segregation happens in partitions.
One partition has a fixed processing time slot and a
fixed memory area. In no case can partitions influence
each other [12], [13]. IMA systems are configured
statically. All partitions, all peripherals, and all communication paths are defined in configuration files
for each module separately and loaded once during
integration.
