(b)
The computer must be de-energized for a time of:
-
A/C in config. A-: 10 sec
-
A/C in config. B-: 10 sec
-
A/C in config. C-: 10 sec
-
A/C in config. D-: 10 sec

(2) Progress of Power-Up Test The time durations below are only valid if the CAM has been already loaded before the power-on was performed. The CAM loading requires approx. 15 sec.
(a) Duration:
-
A/C in config. A-: approx. 35 sec until the system is operational, approx. 60 sec until the end of the test
-
A/C in config. B-: approx. 40 sec until the system is operational, approx. 70 sec until the end of the test
-
A/C in config. C-: approx. 10 sec until the system is operational
-
A/C in config. D-: approx. 170 sec until the system is operational, approx. 200 sec until the end of the test
NOTE : The stated values are typical values and may be increased
____ under certain conditions.
(b) Flight compartment repercussions (ECAM warning, audio warning, pushbutton flashing..if any..): A/C in config. A-, B-,C- or D-.
1_ ECAM maintenance status:
'CIDS 1' and/or 'CIDS 2' come on and go off after completion
either:
- at the same time or,
- seperately or,
- approx. 30 sec after completion of the power-up test.
2 Audio Control Panel:
_
-ATT light flashes for approx. 60 sec
NOTE : The following repercussions can be observed in the
____ cabin: A/C in config. A-:
-after approx. 30 sec cabin lights go off for approx. 2 sec
-chime(s) is(are) heard 40 sec after power-up test
initialization A/C in config. B-:
-
after approx. 30 sec, the cabin lights go off for approx. 2 sec
-
after approx. 35 sec, the signs flash for approx. 1 sec

-and chime(s) is(are) heard approx. 35 sec after
power-up test initialization A/C in config. C-:
-no observations A/C in config. D-:
-
after approx. 30 sec, the cabin lights go off for approx. 2 sec
-
after approx. 35 sec, the call/seatrow numbering lights and the signs flash for approx. 80 sec
-chime(s) is(are) heard approx. 170 sec after power-up test initialization
(3) Results of Power-Up Tests Flight compartment repercussions (if any) in case of test pass/test failed.
(a)
Test pass :
-none
(b)
Test failed :
1_ In case of CIDS 1 or CIDS 2 failure:
- ECAM maintenance status:
'CIDS 1' or 'CIDS 2' white indication
2 In case of CIDS 1 and CIDS 2 failure:
_
-Master caution light comes on and 1 single chime
-ECAM warning: 'COM CIDS 1 + 2 FAULT' 'CIDS' (INOP system)
G. CIDS Director switchover In case of Director 1 failure the activity is switched to the stby Director 2.
(1)
A/C configuration: A- Landing gear not compressed B- Landing gear compressed and all doors closed C- Emergency mode (only essential power available) D- Landing gear commpressed and with a minimum of one door open
(2)
Duration: The time mesurement has been started with the Director 1 power-off. Before the switchover simulation, the CAM has been already loaded.
-A/C in config. A-: approx. 25 sec until the system is operational and the end of the test
