A. System Test NOTE : This note is for RA1 test, for RA2 test you must open the circuit breaker 1SA1. If you do this test in descent, you can make sure that the auto call out announcements are correct. To do this, set a small SLOPE. To decrease the total test time, increase the speed of the altitude change. To do this, adjust SLOPE to a larger value or set a lower STOP ALT.

1. On the MCDU: On the MCDU:
-push the line key adjacent to - the LRRA1 (LRRA2) RAMP TEST page
the RA1 (RA2) indication. Then comes into view.

* START ALT : 0 ft. * + 0 ft.
* STOP ALT : 2500 ft. * + 2500 ft.
* SLOPE : 25 ft/s. (Ref. NOTE). * 25 ft/s.
- push the line key adjacent to the TRIGGER indication. On the CAPT and F/O PFDs, the ramp teststarts. The speed scale moves up to 2500 ft. and stops after approximately 1 minute 40 seconds.
On the MCDU, the RAMP TEST PROCESSING message comes into view. When the altitude increases:
- on the CAPT and F/O PFDs: . when the altitude is between 0 and
160 ft., the horizon line moves down. The elevation scale comes into view.
. when the altitude is between 0 and
570 ft., the red ribbon adjacent to the altitude scale moves down and
then it goes out of view.
- push the line key adjacent to the RETURN indication. On the MCDU:- the LRRA1 (LRRA2) page comes into view.

________ Subtask 34-42-00-860-053On the MCDU:
-
the RA1 (RA2) RAMP TEST page comesinto view with these indications:TWO SUCCESSIVES RAMPS:RAMP1: 500-50FT (10FT/S) RAMP2: 50-0FT (3FT/S) MAKE SURE THAT AUTO CALL OUT ALTITUDES ARE CORRECTLY ANNOUNCED
On the CAPT (F/O) PFD:
-
the ramp test starts. The speed scale moves down from 500 to 0 ft. and stops after approximately 1 minute.
-when the altitude is between 500 and 0 ft., the red ribbon adjacent to the altitude scale moves up.
On the MCDU:
-at the end of the test, the TEST OK page comes into view.
