AMMS
Aircraft and Mission Management System
The AMMS is a powerful computing system designed to provide processing features to rotary wing aircraft, including Navigation & Flight Management, Cockpit Display Management, and Aircraft Plants Management.
The System is composed of:
- Two AMMCs Units (the Computer Core)
- Two Data Transfer Units
- A Control Panel
The AMMS provides the capabilities to acquire, process, and manage information and aircraft plant data from EFIS/EICAS, relevant CNI equipment, and AFCS, in a reliable, high performance environment. It is based upon a core consisting of two identical computers (AMMC, Aircraft and Mission Management Computers), synchronised and concurrently performing the same operations in a master/hotstandby architecture, which allows, in case of failure of the Master, a totally automatic reconfiguration for all system functionalities, therefore resulting in a high mission availability.
