Automatic aircraft powerplant control

An automatic aircraft powerplant control system, comprising:

• a throttle control configuration for controlling a throttle, comprising:
• a throttle servo mechanically coupled with an engine via a throttle control linkage, wherein the throttle servo is configured for adjusting a throttle valve via the throttle control linkage;
• a throttle control lever communicatively coupled with the throttle servo for providing a user input to the throttle servo;
• and
• a throttle controller communicatively coupled with the throttle servo for controlling the throttle servo;
• a dual-redundant propellor servo drive for providing propellor control, comprising:
• a first propellor servo mechanically coupled with the engine via a first propellor control linkage, wherein the first propellor servo is configured for adjusting a propellor governor setting of the engine;
• and
• a second propellor servo mechanically coupled with the engine via a second propellor control linkage, wherein the second propellor servo is configured as a backup to the first propellor servo for adjusting the propellor governor setting of the engine;
• and
• a dual-redundant mixture servo drive for controlling an air-fuel mixture, comprising:
• a first mixture servo mechanically coupled with the engine via a first mixture control linkage, wherein the first mixture servo is configured for providing a mixture control output to the engine via the first mixture control linkage;
• and
• a second mixture servo mechanically coupled with the engine via a second mixture control linkage, wherein the second mixture servo is configured for providing the mixture control output to the engine via the second mixture control linkage.
