1. Verify the Test Set is powered ON. Ensure Initialization has completed, the system is
safe at Ground and the display indicates “Vented.”
a) If required, select Go To Ground and wait for the
Test Set to indicate “Unit Safe at
Ground.
”
2. Connect the hoses, both Static (Ps) and Pitot (Pt) to the Test Set ports
– hand-tighten
only.
Note
: The Pitot (Pt) hose is not required to perform a Static system test however, it is
highly recommended as a safety precaution to protect the ASI from possible
damage.
3. If not already accomplished, perform a Leak Test on the Test Set and hoses.
Note
: Cap the aircraft end of each hose
– hand-tighten only.
4. Connect the hoses to the aircraft Static (Ps) and Pitot (Pt) ports.
5. Verify that the alternate pneumatic system(s) (co-pilot, standby auxiliary, etc.) share the
same pneumatic lines. If so, they must be sealed or isolated from the current pneumatic
system about to be tested.
6. If necessary, change the displayed parameters on the Test Set to those required. This
can be accomplished by touching “Display Setup” from the Main Menu. From the
“Display Setup” screen, select the desired aeronautical parameters.
7.
If necessary, different units can be selected by touching the “Units” icon from the main
menu. From the “Units” screen, touch the desired units.
8. Ensure the limits selected are appropriate for the aircraft and or Instruments that are
going to be tested.
9. If there is a height difference between the Test Set and the aircraft or instruments
about to be tested, enter the Altitude Correction.
a)
From the Main Menu, touch the blue icon “page 2.” Select “Setup 1.” Touch
“Altitude Correction” from the “Limits View/Select” screen. A yellow screen is
displayed. Touch “OK” to display the “ALT Correction” keypad screen. Input,
altitude difference (with aircraft / instruments higher than Test Set the value would
be entered as a (+) positive number).
10. At this time confirm the following has been accomplished:
a) The Test Set and hose combination have been leak tested.
b) The Test Set hose(s) Static (Ps) and Pitot (Pt) has been connect to the aircraft or
instrument to be tested.
c) The Test Set limits have been configured with the appropriate vales to protect the
aircraft system or instrument(s) about to be tested.
d) If required, the altitude correction value has been entered.
11.
Select the “Control” icon.
a) The Test Set will transition from Leak Measure to Control mode. You will notice the
ALT and CAS target will be preloaded with the current pressure altitude and CAS
values.
b) Wait for Resuming Control phase to complete (typically 4 seconds).
12. Set the ROC Target value as specified by the AMM, CMM, or AP.
13. If required, set the value for RtCAS as specified by the AMM or CMM. The default
value is 300 kts/min.
