D. Connection of the Ground Pressure Generator
(1) Remove the slip on covers from the static probe and the pitot probe of the standby system.
R (2) Connect the GENERATOR - GROUND PRESSURE MINI. 100 MB (1.45 PSI) TO
R 1400 MB (20.3 PSI) to one standby static probe with the STATIC PORT ADAPTER (98D34003500100) from the ADAPTER COVER-STATIC PORT (98D34003500100).
(3)
Connect the ground pressure generator to the standby pitot probe with the ADAPTOR-CHARGING,PITOT PROBE.
(4)
Seal the Stby 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 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.
(a)
Seal the drain holes of the pitot probe with a piece of plastic and colored adhesive tape of very bright color.
(b)
Seal the opposite standby static probe with a piece of plastic (see CAUTION above) and with the STATIC PORT COVER (98D34003500103) from the ADAPTER COVER-STATIC PORT (98D34003500103).
(5) Start the ground pressure generator.
