4. Procedure
_________
Subtask 34-13-00-790-050
A. Leak Test of the Main Air Data System
NOTE : You can do the test below for a static pressure of 697 hPa (10,000
____ ft) and an impact pressure of 53.5 hPa (180 Kts) but it is less accurate. After 5 min:
-
the change of altitude must not be more than 275 ft.
-
the change of speed must not be more than 10 Kts.
NOTE : The difference between the input parameters for the ground test
____ (speed and altitude) and the values shown on the cockpit displays, is normal.
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1.
On the glareshield 13VU ,on the EFIS control section of the FCU, set a barometric pressure of 1013 hPa.
2.
On the ground pressure generator:
-
set a static pressure of 465.5 hPa (20,000 ft).
-
set an impact pressure of 176 hPa (320 Kts).
3.
Close the electrovalves to isolate the static and total pressure lines of the aircraft from the pressure generator.
4.
On the pressure generator:
-slowly balance the pressure in the main static and total pressure lines
- open the electrovalves to get atmospheric pressure.
After 5 minutes, on the CAPT (F/O) PFD:
-
make sure that the change of altitudeis not more than 320 ft.After 10 minutes, on the CAPT (F/O) PFD:
-
make sure that the change of speed is not more than 10 Kts.
The rate of descent must not be morethan 6000 ft/mn.
