Beacon codes that end with the numerals "00" are known as what?

Beacon codes that end with the numerals "00" are referred to as nondiscrete codes. These codes are used within the air traffic control system to convey specific information about an aircraft's identity, status, or operational conditions but do not correspond to a unique aircraft by a predefined discrete code. Instead, nondiscrete codes might be used in various contexts where discrete identification is not necessary or where the aircraft is functioning in a specific capacity that does not require its individual identification to air traffic control.

Nondiscrete codes are often utilized for the purpose of facilitating communication within a larger group of aircraft or for specific operational procedures. This allows for a more streamlined identification process in scenarios where individual identification may be less critical.

Understanding this concept is crucial for effective radar operation and communication in air traffic control, as it showcases how different types of beacon codes serve various roles in maintaining situational awareness and operational efficiency.
