The engine control unit MCU II is build up out of the operating unit in the
instrument panel (see picture above) and a control unit (below the rear seat pan).
With the MCU II the operation of the engine and the extension- resp. the retraction
of the power plant run automatically to a great extend. Furthermore the MCU II
supplies the Pilot with information regarding the most important operational
parameters of the engine.
The operational state of the engine and the position of the power plant and the
propeller are determined processing the information of the control unit, of the two
limit switches, of the RPM-sensor and of the two sensors for the vertical
positioning of the propeller.
The extension and the retraction of the power plant is automated to a great extend
and connected to the ignition switch. Logical inquiries secure the engine control
against accidental operating errors.
In addition also a largely manual operation of the power plant is possible.
