A. Functional Test of the Altitude and Airspeed Data
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
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 Trim 0) 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 Trim 0) and the ADIRU 1.
The rate of descent must not be morethan 6000 ft/mn.
