B. Aircraft configuration
(1)
Put the safety barriers and the warning notices in position to keep persons out of the work area.
(2)
Put the vertical speed indicator and the absolute pressure indicator/digital indication/sensitivity 1mbar(0.01PSI) in position in the cockpit.
(3)
Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-002).
(4)
Make sure that the avionics equipment ventilation operates correctly. NOTE : if during this test, the avionics equipment ventilation stops,
____
you must stop the test.
(5)
In the avionics compartment:
(a)
Put the safety plug - ref MS21913-4 with its O-ring - ref NAS1612-4 on the air inlet of the pressure switch 16WR.
(b)
Put a safety streamer on the safety plug.
(6)
We recommend that you remove the crew oxygen masks (Ref. TASK 35-12-41-000-002)
NOTE : This test requires an absolute pressure higher than the cabin
____ pressures you get during usual aircraft operations. The crew masks have an aneroid capsule that is usually resistant to the absolute pressures you can get during this test.
But, to prevent high stress on the aneroid capsule, we recommend the removal of the crew oxygen masks.
(7)
On the AIR COND panel 30VU:
-make sure that the PACK 1 and PACK 2 pushbutton switches are pushed (the FAULT legends are on).
(8)
On the CABIN PRESS section of the panel 25VU:
-release the MODE SEL pushbutton switch (the MAN legend is on).
(9)
On the EXT LT section of the panel 25VU:
-set the BEACON switch to ON.
(10)
Do the EIS start procedure (Ref. TASK 31-60-00-860-001).
(11)
On the lower ECAM display unit, on the CAB PRESS page:
-make sure that the outflow valve 10HL is in the fully open position.
(12)
On the VENTILATION section of the panel 22VU:
-
release the EXTRACT pushbutton switch (the OVRD legend comes on).
-
release the CAB FANS pushbutton switch (the OFF legend comes on).
(13)
On the CARGO HEAT section of the panel 22VU:
-make sure that the AFT ISOL VALVE pushbutton switch is released (the OFF legend is on).
(14)
On the lower ECAM display unit, on the CAB PRESS page:
-the skin air-inlet (INLET) and skin air-outlet (EXTRACT) valves are closed.
(15)
Close and lock the sliding windows and all access doors to the pressurized area.
