F. General Functions of the DMU
(1) Identification of Location The design of the DMU allows its use in A/C with different input parameters and different tasks for data evaluation, if the appropriate programs are implemented. To ensure this capability, the unit is able to identify A/C type information on the FDIU ARINC 429 DITS data bus. Depending on the occurance of specific conditions or events, the DMU is trigger predefined actions. As a result of specific trigger conditions AIDS reports may be generated or data may be recorded on the DAR (optional) or stored in the DMU internal Smart Access Recorder (SAR). Print reports can be either printed out on the cockpit printer or transmitted via ACARS (optional). SAR data are also retrieved via the Portable Data Loader (PDL). Functions which are specific to A/C type (CFMI or IAE engines) are indicated in the respective logic definition.
