Chapter 6. Reference
When using a single instrument, the pressure supply must be changed when changing from
Altitude to Airspeed.
6.15.3 Example of Altitude and Airspeed Testing
This example shows how two-channel PACE instruments can be used to generate altitude and
airspeed.
6.15.4 Units
The units can be either the aeronautical or pressure units. The units can be changed any time
between pressure and pressure converted to aeronautical units. The display shows the output
CAUTION Before testing, set the rates of change for both pitot and static to a
safe value. A high rate of change can damage sensitive aeronautical
components. Refer to the appropriate component maintenance manual for the
unit under test.
In this example configuration, negative airspeed can be generated this can
damage an airspeed indicator. To prevent negative airspeed, apply the static
pressure before the pitot pressure for increasing and decreasing airspeed
values.
