ABSTRACT:
An apparatus and method for rigidly interlocking a control wheel and the rudder pedals of an aircraft is provided for securing the control surfaces of the aircraft operated by the control wheel and the rudder pedals in a stable position. The apparatus comprises a pair of control wheel retaining members rigidly connected to one end of a rod member in a spaced apart, parallel relationship with one another for retainingly engaging opposing radially extending portions of the control wheel and a pair of rudder pedal retaining members rigidly connected to one end of another rod member in a spaced apart, parallel relationship with one another for retainingly engaging a lever of each of the rudder pedals. The rod members are disposed in a telescoping relationship with respect to one another and are adjustably securable whereby the control wheel retaining members are rigidly locked in a selected position relative to the rudder pedal retaining members wherein the control wheel retaining members cooperate with the rudder pedal retaining members to secure the control wheel in a level position, the control column in an inward position, and the rudder pedals in a neutral or centered position.
