Functional Test of the Air Data Module (ADM) with the Aircraft Integrated Data System (AIDS)

CAUTION: TO PREVENT DAMAGE TO INSTRUMENTS, OBEY THESE PRECAUTIONS WHEN YOU DO THE TEST:

THE PRESSURES SET MUST NOT BE MORE THAN 1050 hPa (31 in Hg) OR LESS THAN 115 hPa (3.39 in Hg)
CHANGES IN STATIC AND TOTAL PRESSURES MUST NOT BE MORE THAN 6000 FEET/MINUTE
DO NOT SUDDENLY OPEN LINES TO AMBIENT AIR WHILE THE PRESSURE GENERATOR IS CONNECTED.

C. Installation of the Ground Pressure Generator
(1) Remove the slip-on covers from the static probes and the pitot probes.
(2) Connect the static port of the ALT34100001 PITOT AND STATIC TEST SET to the static probes and/or the pitot probes on which you do the test.

Static and Pitot Test Set

(a) The static probes with the ADAPTER STATIC PROBE:
1 For the CAPT circuit (Air Data/Inertial Reference Unit 1 (ADIRU 1)) and the F/O circuit (ADIRU 2):

7DA1 zone 127 Station (STA) 8750 for the left static-pressure ADM (19FP5)
7DA2 zone 127 STA 8700 for the left static-pressure ADM (19FP7)

And

8DA1 zone 128 STA 9300 for the right static-pressure ADM (19FP4)
8DA2 zone 128 STA 9350 for the right static-pressure ADM (19FP6).

(b) The static probes with the ADAPTER STATIC PROBE:
1 For the standby circuit (ADIRU 3):

7DA3 zone 121 STA 4250 for the static pressure ADM (19FP8), or
8DA3 zone 122 STA 4250 for the static pressure ADM (19FP8).

(c) The pitot probes with the ADAPTER PITOT PROBE:
1 For the CAPT circuit (ADIRU 1):
a 9DA1 zone 125 STA 5500 for the total pressure ADM (19FP1).
2 For F/O circuit (ADIRU 2):
a 9DA2 zone 126 STA 5500 for the total pressure ADM (19FP2).
3 For the standby circuit (ADIRU 3):
a 9DA3 zone 125 STA 5500 for the total pressure ADM (19FP3).
(3) Seal the standby probes:

CAUTION: WHEN YOU SEAL THE DRAIN HOLE IN THE PITOT PROBE, DO NOT SEAL THE HOLE DIRECTLY WITH THE COLORED ADHESIVE TAPE. ALWAYS PUT A PIECE OF PLASTIC ON THE HOLE FIRST AND USE THE COLORED ADHESIVE TAPE TO ATTACH THE PLASTIC. IF YOU SEAL THE DRAIN HOLE DIRECTLY WITH THE ADHESIVE TAPE, THERE IS A RISK THAT SOME OF THE ADHESIVE WILL STAY ON THE HOLE AND COLLECT PARTICLES. THIS CAN SUBSEQUENTLY CAUSE BLOCKAGE OF THE HOLE AND THUS INCORRECT OPERATION OF THE PROBE.

(a) Seal the drain holes of the pitot probes with a piece of plastic and/or the TAPE - ADHESIVE of very bright color.
(b) Seal the opposite static probe of the standby ADM with the 98D10103500001 COVER-STATIC PROBE.
(4) Start the ground pressure generator.
