What does the aircraft respond with when interacting with Mode S ALL Calls?

When an aircraft interacts with Mode S ALL Calls, it responds with its Individual Address. Mode S, or Mode Select, is a radar beacon system that provides a unique identification for each aircraft, allowing for more precise tracking and interaction. The Individual Address, often referred to as a Mode S address, is a 24-bit code that uniquely identifies each aircraft in the airspace.

This response mechanism is crucial as it allows air traffic control and other aircraft equipped with Mode S transponders to identify and communicate with specific aircraft amidst potentially many others. The response with Individual Address helps reduce confusion and enhances situational awareness in busy airspaces.

Altitude Information, Flight Status, and Response Code may be involved in various operational capacities, but they are not what the aircraft primarily responds with in an ALL Call situation. Instead, the focus is on identifying the specific aircraft through its Individual Address, which is essential for safe and efficient air traffic management.
