Beacon codes ending in 00 are described as which of the following in terms of discreteness?

• A. non discreet
• B. discreet
• C. reserved
• D. standard

Answer: (A)

Discreteness is about whether a beacon code uniquely identifies a single aircraft on radar. When a code ends with 00, it signals a non-discrete, general-use code that can be shared by many aircraft rather than a unique identifier for one aircraft. For example, the common VFR code in the United States is 1200, which ends in 00 and is used by many aircraft, not just one. Codes that do not end in 00 can be assigned as discrete to a specific aircraft for individual tracking. So, beacon codes ending in 00 are described as non discreet.
