[ We claim:] [1.] A control system for an aircraft internal combustion engine, comprising:a first input configured to receive a user defined target engine speed from a power stick;a first adjustment device configured to adjust a rate of fuel injection into the internal combustion engine;a second adjustment device configured to adjust a pitch of a propeller of the aircraft;a second input unit configured to detect an engine rotation rate of the internal combustion engine;a first electronic circuit configured to signal said first adjustment device to adjust the fuel injection rate according to a predetermined rate corresponding to the target engine speed received from said first input unit, said first electronic circuit configured to compare the detected engine speed with the target engine speed and to signal said second adjustment device to adjust the pitch of the propeller so as to maintain the engine speed at the target engine speed;a second electronic circuit configured to signal said first adjustment device to adjust the fuel injection rate so as to maintain the engine rotation rate of the engine, and to prevent adjustment of the propeller pitch;wherein said control system is configured to switch to said first electronic circuit and not said second electronic circuit when the user defined engine rotation rate is within a first range, and wherein said control system is configured to switch to said second electronic circuit, and not said first electronic circuit, when the detected engine rotation rate is within a second range.
