______________________________________________________
 1.
 General

_______ (Ref. Fig. 001) The Flight Augmentation Computer (FAC) dialogues with the other components mainly through ARINC 429 digital information system buses. The figure shows the FAC interconnection. It is to be noted that the FAC data, except maintenance data, are transmitted to the other systems through the FAC main bus.

 2.
 Digital Outputs

_______________ This table contains all the output parameters in the digital form. They are sorted as per the numerical order of their output label. The infomation busses can be different between command and monitor channels: FAC OWN COM bus and FAC OWN MON bus. The following table gives:
 -SYS LABEL SDI: (SDAC, FWC, DMC...) output label for which the parameter is available.
 -PARAMETER DEFINITION: parameter name.
 -RANGE ACCURACY: measurement range. Maximum value transmitted. When the digital value changes, the change step is equal to the accuracy.
 -UNIT: unit in which the digital value is transmitted.
 -SIG BIT: indicates whether a sign bit is available.
 -DATA BITS: number of bits used by the parameter in the label.
 -UPD/MSEC: output transmission interval. The refresh rate is given in
 milliseconds.

 -CODE:
 BNR: binary data word
 BCD: binary coded decimal data word
 ISO: data word coded in ISO5 code
 DIS: discrete data word
 HEX: hexadecimal coded
 HYB: mixed code

 -ALPHA CODE: indicates the parameter mnemonic code.
 -SOURCE ORIGIN: parameter source computer or system.
