1.
 On the ground pressure generator, set a static pressure and a total pressure as given in the tables below.

 2.
 On the SWITCHING panel 8VU:

 -
set the AIR DATA selector to CAPT/3.

-
set the AIR DATA selector to F/O/3.

3.
 At the end of the test, on the ground pressure generator:

 -slowly balance the pressure in the static and total pressure lines.
 - open the lines to get the
 atmospheric pressure.

 4. Stop the pressure generator.
On the CAPT and F/O PFDs, compare andwrite the altitude and airspeed valuesfor the ADIRU 1 and 2.
On the CAPT and F/O PFDs, compare andwrite the altitude and airspeed values for the ADIRU 3 (in relation to the applicable Trim) and the ADIRU 2.
On the CAPT and F/O PFDs, compare andwrite the altitude and airspeed values for the ADIRU 3 (in relation to the applicable Trim) and the ADIRU 1.
The rate of descent must not be morethan 6000 ft/mn.
