What component sends control data to the TCAS computer?

The component that sends control data to the TCAS (Traffic Collision Avoidance System) computer is the IFF/TCAS Control Panel. This panel serves as the interface through which aircrew members interact with the TCAS system. It allows for the configuration and management of TCAS functions, providing critical input data that the TCAS computer uses to determine aircraft proximity and recommend evasive actions.

The IFF/TCAS Control Panel is essential because it not only allows the operator to input settings but also processes signals related to the aircraft’s identification and situational awareness concerning other nearby aircraft. This data is vital for the TCAS system to effectively analyze the surrounding airspace and issue alerts when necessary.

Understanding the role of the proper control panel emphasizes the importance of human-machine interaction in aviation safety systems, ensuring crew members maintain situational awareness through effective communication with onboard technology.
