(3)
Install the ATC ground test unit in the cockpit. Put the antenna of the ATC ground test unit at 50 cm (approx. 2 ft) from the ATC antennas. Connect the antenna to the ATC ground test unit.
(4)
On the SWITCHING panel 8VU, make sure that the AIR DATA selector switch is at NORM.
(5)
On the center pedestal, on the ATC/TCAS control unit:
-
set the ATC system 1(2) on.
-
set the ALT RPTG/OFF/ON switch to OFF.
-
set the AUTO/ON/STBY switch to ON.
-make sure that the display does not show an emergency code: 7500, 7600 or 7700.
(6)
On the panel 13VU, on the CAPT and F/O EFIS control sections of the FCU, make sure that the baro displays show STD.
(7)
Do the operational test of ALT DYNAMIC SLEW TEST (Ref. TASK 34-13-00-710-004) to simulate an altitude of 23,458 ft. On the MCDU, enter 0/23 458 as SLEW LIMITS and push the line key adjacent to the UP (START SLEW) indication to start the test.

4. Procedure
_________ Subtask 34-52-00-720-061
A. Functional Test of the Altitude Reporting Function
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the ATC/TCAS control unit: On the ATC/TCAS control unit: - the ATC FAULT or FAIL indicator light is off.
R R - set the ALT RPTG ON/OFF switch to ON. On the ATC ground test unit a display shows the standard altitude of approx. 23,458 ft or equivalent and the last code set.
The difference between the altitude
shown on CAPT and F/O PFDs and that shown on the ATC ground test unit must not be more than 125 ft.
- set the AUTO/ON/STBY switch to STBY. On the ATC/TCAS control unit:- the display stays on.
