EASY DATALOG SAVING
Easy logging of the data for debug purpose. If needed,
The APR1 unit can save a last ight log on the USB pen
drive. The user can then send the log via e-mail to the
installer for a help/support request.
SINGLE LEVER ENGINE CONCEPT
With APR1, the engine revs are automatically set by the
aircraft's speed which is measured by a built-in sensor
connected to the aircraft's static and pitot ports. A graphic
editor allows the installer to draw the best curve for your
engine-propeller-aircraft combination. The APR1 will be
able to hold the most appropriate RPM for each ight
phase. In this way, your powertrain becomes a Single
Lever Engine. Just move the throttle, and your new
system will take care of all the rest.
ABOUT SAFETY
APR1 has been designed with safety in mind. Its high-
current output in HC models, the rapid short-circuit
protection and the possibility of continuing to operate the
propeller pitch in the event of a failure of the internal
electronics by simply setting the red selector to manual,
make it a state-of-the-art instrument.
The -M- versions are equipped with a Manifold pressure
sensor and through an editable curve MAP/RPM, the RPM
are automatically increased if a pressure value too high for
the current RPM is requested. This avoid engine
overtorque.
