What minimum information must be provided to the controllers?

The minimum information that must be provided to the controllers includes the aircraft identification and relevant details about the runway, intersection, or taxiway being used. This is crucial for effective communication between pilots and air traffic controllers, as it allows controllers to understand which aircraft is communicating with them and where that aircraft intends to operate within the airport environment.

Providing the aircraft ID helps in identifying the specific aircraft for tracking and coordination purposes. Additionally, sharing information about the specific runway or taxiway enhances situational awareness and ensures that both the pilot and controllers are synchronized in their operations, thereby reducing the risk of mishaps and improving overall air traffic safety.

The other options involve information that is either not essential for immediate communication with controllers or pertains to operational aspects not required for every interaction. For example, items like flight plan details or pilot credentials, while important in broader aviation operations, do not need to be conveyed in every instance of communication with air traffic control.
