This paper elaborates and validates an audio system application for an Adaptive Cabin Management System (ACMS) based on the Adaptive Avionics Platform (AAP). A modern approach for avionics is the self-organizing and almost configuration-free AAP. System functions are configured and instantiated without human interaction during an organization phase of the system. A domain where the benefits of the AAP seem most promising are cabin management systems (CMS), where frequent cabin layout changes and updates occur. The AAP offers scaling and modification of CMS with hardly any configuration effort. This opens up the perspective of reusable systems for different types of aircraft making the need for an exclusive system design for a particular aircraft obsolete. The platform ensures fault-tolerance via reconfigurable network paths and master/slave behaviour of computing modules (CPM). In this paper, a cabin audio system for the AAP is presented. The audio system uses cabin interphones (CIP) and cabin speakers (CS) as peripherals to support three typical scenarios: (1) CIP to CIP calls, (2) CIP to CS calls (passenger address) and (3) playback of recorded audio using the flight attendant panel (FAP). The audio system is modifiable and scalable due to its integration into the AAP. Therefore, it can be used in different cabin layouts without the need for hardware configuration. The integration also opens up the perspective for saving weight and resources for development and maintenance of the cabin functionalities. The validation of the audio system concept and its performance is based on an ACMS lab demonstrator and showed that time delay requirements are fulfilled. Time difference requirements for synchronous playback were not met, but comparison with other approaches showed that clock synchronization overcomes this shortcoming.
