System and methods for designing and building regional hybrid-to-electric systems and methods for designing and optimizing regional hybrid-to-electric aircraft

A method, comprising:

• receiving a control input from at least one inceptor to control an aircraft on a first axis from a plurality of axes;
• mixing the control input to alter a position of a multi-axis control surface to control the aircraft about the first axis in response to the control input, the multi-axis control surface providing control of the aircraft in the first axis and a second axis, altering the multi-axis control surface to control an orientation of the aircraft about the first axis decreasing control authority of the multi-axis control surface for the second axis;
• tracking remaining control authority of the multi-axis control surface for the second axis using a time dependent algorithm in response to the position of the multi-axis control surface being altered in response to the control input;
• imposing a soft stop on the at least one inceptor in response to the remaining control authority of the multi-axis control surface for the second axis reaching a limit;
• and
• in response to receiving an instruction to exceed the soft stop, reducing the remaining control authority of the multi-axis control surface for the second axis.
