ACMS is a highly integrated, civil certified and military qualified Communications Management System. The ACMS features Audio Management (including intercom), Radio Management and Radio Navigation Equipment Management. It provides facilities for the generation, integration and management of aircraft audio warning signals, in the form of tones and voice messages. The ACMS can be configured for all communication management requirements in all types of aircraft, a flexible and future proof solution.

The ACMS is a very flexible control and display system for the management of aircraft communications and radio navigation equipment integrating digital audio and equipment control facilities. ACMS also features full intercom capability. The software programmable Human Machine Interface (HMI) allows for the customisation of systems for different users and aircraft. The open architecture of the ACMS allows integration of any customer selected radio and radio navigation equipment. The ACMS can be regarded as a sub-element of the core avionics of an aircraft. The ACMS can be scaled. Functions in the system are under software control and therefore the ACMS can satisfy the communications requirements of any aircraft type, e.g. helicopters, fighters, light and heavy transport aircraft, etc.

The ACMS can be configured to provide secure communications capabilities by fulfilling requirements for compromising emanation (TEMPEST compliant) and separation of secure and general (red and black) communication.

Three building blocks are available, namely the General Control Panel (GCP), the Remote Control Panel (RCP) and the General Interface Unit (GIU). These building blocks are interconnected by means of a 2 Mb/s dual redundant Digital Communications Bus (DCB) in a token ring configuration. Systems may be configured using only one building block, i.e. the GCP, or all three in a comprehensive solution.
The ACMS can be integrated with an aircraft avionics system via standard interfaces. This feature allows for further automation and therefore reducing pilot workload. The capability to control the radios and radio navigation equipment from a Multifunction Central Display Unit (MCDU) via the ACMS is available.

The ACMS can be programmed with radio channel databases (Complans) prior to a mission. ACMS health status data, including health status data of the peripheral equipment connected to it, can be extracted from the ACMS after a mission by an Aircraft Data Loader (ADL).
