Which statement describes the 2nd stage mixing?

• A. It combines inputs from the 1st stage mixing
• B. It splits inputs into multiple axes
• C. It stabilizes in hover
• D. It sets rotor speed

Answer: (A)

Second stage mixing blends the outputs produced by the first stage into the final commands that drive each rotor or actuator. It takes those stage-one results and combines them so that roll, pitch, yaw, and throttle are coordinated and translated into the actual rotor speeds or cyclic inputs needed to achieve the commanded motion. This is why it’s described as combining inputs from the first stage. The other ideas describe different roles: splitting inputs into axes is an input decomposition step, stabilizing in hover is a control goal, and setting rotor speed is an actuator outcome rather than the mixing process itself.
