C. Installation of the Main Air Data System
(1) Remove the slip on covers from the static probes and the pitot probes of the main system.
R (2) Connect the static port of the GENERATOR - GROUND PRESSURE MINI. 100
R MB (1.45 PSI) TO 1400 MB (20.3 PSI) to the static probes with the ADAPTER COVER-STATIC PORT (98D34003500102). For CAPT circuit (ADIRU 1) and F/O circuit (ADIRU 2):
-
L static probe 1 7DA1, zone 127, STA 8750, for the LH static pressure ADM (19FP5)
-
L static probe 2 7DA2, zone 127, STA 8700, for the LH static
pressure ADM (19FP7)
and
-
R static probe 1 8DA1, zone 128, STA 9300, for the RH static pressure ADM (19FP4)
-
R static probe 2 8DA2, zone 128, STA 9350, for the RH static pressure ADM (19FP6).
(3)
Connect the ground pressure generator to the pitot probe with the ADAPTOR-CHARGING,PITOT PROBE. For CAPT circuit:
-
pitot probe 1 9DA1, zone 125
For F/O circuit:
-
pitot probe 2 9DA2, zone 126.
(4)
Seal the drain holes:
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 AND USE THE 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.
Seal the drain holes of the pitot probes with a piece of plastic and/or colored adhesive tape of very bright color.
