Which type of beacon codes do NOT end with the numerals "00"?

The choice indicating that discrete codes do not end with the numerals "00" is based on how discrete codes are structured. Discrete beacon codes are specifically assigned to individual aircraft or flights, and these unique identifiers typically fall within established ranges, which often do not include codes that conclude with "00". This is essential for air traffic control, as it allows for improved tracking and identification of specific aircraft within the airspace.

In contrast, nondiscrete codes are more generic and can encompass a broader range, including "00" ending codes. Formation codes are used for specific coordinated groups of aircraft, and general codes include a variety of designations that may also conclude with the "00" numerals. Understanding the unique characteristics and purposes behind each type of beacon code is crucial for effective radar operations and ensuring efficient aircraft identification and management in controlled airspace.
