4. Procedure ** ON A/C 001-008, 031-039, 101-129, 131-132, 151-199, 226-226, 603-699, 751-799, 801-849, 901-945, 947-999 POST SB 34-1160 for A/C 001-008, 031-039, 101-129, 131-132, 226-226, 901-945, 947-950 Subtask 34-52-00-720-061-C A. Functional Test of the Altitude Reporting Function ACTION 1. On the ATC/TCAS control unit: - set the ALT RPTG ON/OFF switch to ON.

- set the AUTO/ON/STBY switch to STBY.

RESULT On the ATC/TCAS control unit: - the ATC FAULT or FAIL indicator light is off. 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. On the ATC/TCAS control unit: - the display stays on.
