What should be assigned to aircraft in a formation when necessary?

When managing aircraft in a formation, assigning a beacon code is essential because it allows air traffic control to uniquely identify and track each aircraft within the formation on radar. This is particularly important in maintaining safety and situational awareness, as it ensures that controllers can monitor the movements of each individual aircraft while they are closely grouped together. By assigning different beacon codes, controllers can differentiate between the aircraft, helping to prevent any potential conflicts or miscommunications regarding their positions and intentions.

In essence, using a beacon code bolsters the overall efficiency of air traffic management, especially in scenarios where multiple aircraft may be maneuvering closely together. It enhances the ability to provide precise instructions and maintain a clear separation, which is critical for safe operations in controlled airspace.
