B.
FM Level Computation of RESANA from the results of the FM and MCDU safety tests.
-Transmission of malfunction reports : The malfunction reports are sent to the FIDS on the FMGC OWN line in a manner similar to that described in ATA REF 22-91-00 (para 3.B.(7)).
C.
Overall Result Indication
The FIDS memorizes the FG and FM AFS TEST result.
(1)
Correct FG and FM result
In this case the indication is PASS.
(2)
Incorrect FG and/or FM result
The indication is PRESS LINE KEY.
(a)
FG incorrect
The computer concerned is the FMGC.
(b)
FM incorrect The computer concerned is the FMGC, but FM section is specified.

_________ The following figures show an example of AFS TEST utilization from the selection of the AFS TEST option on the AFS MAIN MENU to the primary data of the analysis performed during the test. Utilization:
-Message : FMGC1; FMGC1 internal fault
-RESANAM : * type : AFS TEST, ground area
*
S : 0 ; fault not symmetrical
*
CD : 0 ; no 3rd phase analysis in the FIDS
*
error code : O1H ; FMGC OWN F/W
*
event : 1 ; AFS TEST
-Snapshot utilization. Word 5 : bit 3 = 0 ; A/THR TEST FAILED Safety test of the A/THR function incorrect on the MONITOR side. (Ref. Fig. 001, 002)
