-
The COMMAND side of the FAC and the FIDS have a common power supply.
-
The characteristics of this electrical power supply are described in ATA Ref. 22-67-00: Electrical and Hydraulic Power Supply (FAC).

C. FIDS - BITE Interface R (Ref. Fig. 011)
-
The CFDIU sends a control word (label 227) in compliance with ABD018 on its FIDS bus.
-
The FIDS sends control words 354, 355, 352 and 353 to FAC1, FAC2, FMGC1 and FMGC2 respectively on its FAC1 bus. Words 355, 352 and 353 are transmitted via the FAC1 general bus.
-Each FAC and FMGC transmits words 350 and 351, either spontaneously during transmission of a malfunction report, or after a FIDS command.
-Finally, the FIDS transmits a message on word 356 to the CFDIU.
D. Interface with FMGC1 The FMGC1 transmits labels 040, 041, 042 (CITY PAIR) and 233, 234, 235 and 236 (FLIGHT NUMBER) to the FIDS. The FIDS transmits this information to the CFDIU.

6. Operation_________
A. General
(1) Normal Mode
The use of the system in normal mode is described in ATA REF
31-32-00.
(2) Menu Mode
R - Access to the main menu of the FIDS: chaining of the operations
R enabling display of this menu is described in figure:
R (Ref. Fig. 012)
- Operating principle:
Chaining of the various pages of the menu mode is described in
figure
R (Ref. Fig. 007)
The following pages show an example of LAST LEG REPORT utilization.
R The utilization principle is the same for the other options of the
R menu because the displayed data are the same.
- Example of LAST LEG REPORT utilization
R (Ref. Fig. 013, 014)
These figures describe the access to the last flight failures.
- Example of LAST LEG REPORT utilization
R (Ref. Fig. 015)
This figure describes the elements associated with a given failure.
R A snapshot must not be used at the maintenance level because the
R analysis of the snapshot requires a high engineering level.
R Message: ADIRU 1
R Failure issued by: FAC 1 COM
R RESANA: * Type/symetry: 7 ; flight and symetry
R * Error code: 17 ; IRS OWN F/W
R * EVENT: 6 ; monitoring of peripherals
Snapshot utilization (vendor only):
R Word 1: bit 8 = 0 ; IRS OWN NOT VALID
R Word 2: bit 13 = 0 ; IRS OWN ACQ NOT HLTY
