4.1 Propeller test
Select it to execute a propeller self-test before take-o.
The device will increase the propeller pitch to check the
correct working of the regulator/propeller system, then it
will bring it back to minimum pitch.
To execute this test you must rev up the engine to an
appropriate value (for example 4500 RPM for a ROTAX
912) and press the knob conrming to start the propeller
test.
The APR1 will increase the pitch until the propeller reach
the RPM value your installer has dened.
Once reached this minimum value (4000 RPM for
example) it returns to the initial RPM (in this example 4500
RPM).
While the APR1 is performing the Propeller-test, you can
press the knob or the INC/DEC switch to stop the test and
to bring the propeller to the minimum pitch position.
