Single lever control system for engines with multiple control modes

An aerial vehicle, comprising:

• one or more turbine engines;
• a first engine control subsystem for the one or more turbine engines;
• a second engine control subsystem for the one or more turbine engines;
• a first control lever having a first position corresponding to a minimum power setting of the first engine control subsystem and a second position corresponding to a maximum power setting of the first engine control subsystem;
• a second control lever having a third position corresponding to a minimum power setting of the second engine control subsystem and a fourth position corresponding to a maximum power setting of the second engine control subsystem;
• and
• a mechanical link configured to selectively couple to the first control lever and the second control lever, the mechanical link providing an offset between the first control lever and the second control lever such that for at least a subset of control positions of the first control lever, a resulting power setting of the second engine control subsystem is less than a resulting power setting of the first engine control subsystem.

An engine control system, comprising:

• a first control lever coupled to an electronic engine control subsystem for one or more turbine engines, the electronic engine control subsystem configured to regulate fuel flow to the one or more turbine engines;
• a second control lever coupled to a backup engine control subsystem for the one or more turbine engines, the backup engine control subsystem configured to regulate fuel flow to the one or more turbine engines in the event of a failure of the electronic engine control subsystem;
• and
• a coupling device configured to selectively couple the first control lever to the second control lever with at least one angular offset, the coupling device including a support member having a fixed connection to the second control lever, the coupling device including a selective coupling mechanism having a fixed connection to the first control lever and a selective connection to the support member.
