What data is contained in Field 2 of FDIO messages?

Explanation:
In FDIO messages, the field for the aircraft’s identity is the Aircraft ID. This identifier is designed to uniquely reference the specific airframe across messages, so the system can consistently link all data to the same aircraft even if the flight number or other details change. Flight numbers vary with each leg of a trip, and origin date isn’t a stable identifier for the aircraft. Tail numbers (registrations) identify the aircraft legally, but the FDIO format uses a separate Aircraft ID to maintain a consistent internal reference.
