True or False: A Full Data Block that appears automatically when an aircraft squawks a beacon code assigned by the computer indicates positive identification.

A Full Data Block automatically appearing when an aircraft squawks a beacon code assigned by the computer is a strong indication of positive identification. This means that the radar system has successfully correlated the aircraft's transponder response with the appropriate data it maintains, confirming the aircraft's identity.

The Full Data Block typically includes critical information such as the aircraft's identification, altitude, and flight data, and is essential for effective air traffic control. When an aircraft squawks a beacon code assigned to it, it enhances the controller's ability to associate the radar returns with the specific aircraft being monitored, thus affirming positive identification.

In the context of air traffic control practice, having a reliable and automated means of identifying aircraft is crucial for maintaining safety and efficiency in busy airspace.
