noise generation within the CTL-92 control panels that the transponder can interpret and transmit as a random altitude. Air traffic control and traffic alert and collision avoidance system (TCAS)-equipped aircraft can interpret these erroneous random altitudes as valid altitudes.

            This Directive requires modification of the altitude encoder inputs of the CTL-92. This action is intended to prevent erroneous altitude interpretations, which could result in reduced vertical separation or unsafe TCAS resolution advisories.
