An apparatus for interconnection in a helicopter tail rotor control linkage for changing the pitch of the tail rotor blades in response to predetermined inputs is provided. The apparatus comprises a linkage member having a variable geometry, an actuator, and a control unit. In a preferred embodiment, the control unit utilizes a microcontroller to monitor inputs corresponding to ambient air condition and automatically vary the maximum tail rotor pitch so as to provide maximum tail rotor authority over a range of altitudes.
