Select AIRSPEED LEAK TEST:

If necessary, SELECT AERO UNITS:

2.4.1  Method

1. Connect the instrument to the pitot system as shown in Figure

 

4. Ensure that the static 

system is vented to atmosphere before starting the test.

2. Close the release valve and manual let-down valve and, using the hand-pump, generate the 

required airspeed.

3. Set WAIT and DURATION of leak test times:

4. When ready, press the RUN key (F2):

Note: 

Initially, the WAIT period counts down, followed by the timing period. The START 

SPEED is recorded as soon as the timing period starts. At the end of the test the display 

shows the complete details of the test.

5. Record the displayed operating data.
6. Allow the airspeed to decrease until it is below 80

 

kts.

7. Slowly open the manual let-down valve to return the system to zero (ground level).
