PACE Pressure Controller User Manual
[EN] English 6 - 33 K0443 Revision A
Aeronautical option
The aeronautical option is a specialised application of the PACE instrument.
Special application note: The PACE instrument must be set-up very carefully so that the
aeronautical pressures applied do not exceed maximum pressure values and rates of
change.
Leak testing
Cautions
Do not exceed the maximum pressures stated in the appropriate Component
Maintenance Manual for the unit under test.
Carefully de-pressurize all pipes to atmospheric pressure before disconnecting and
connecting to the unit under test.
Before testing an aeronautical component do a leak test.
This task sets the test pressure, dwell time at the test pressure and the leak test time.
At the start of the test, the instrument applies a test pressure to the user system.
A dwell time allows the user system to stabilise.
Aeronautical testing
The aeronautical task enables control and measurement of the following:
• Altitude (feet/metres)
• Airspeed (knots, mph, km/h)
This task utilises dual pressure displays to show the parameter and the rate of change of the
following:
•Altitude
•Airspeed
• Mach and Airspeed with Mach number
The aeronautical task enables the testing and calibration checking of aeronautical
indicators and system components by controlling and displaying values and rates in
aeronautical units.
When using a single instrument, the pressure supply must be changed when changing from
