What coordination ensures handover between FIRs?

• A. AFTN or surveillance handover
• B. Direct radio handover
• C. Manual handover
• D. Handover through satellite link

Answer: (A)

Handover between FIRs is ensured by coordinating exchanges of information through AFTN and by transferring the surveillance responsibility. AFTN provides the standardized messaging and flight data (such as position, route, flight plan, and clearances) needed by the receiving FIR to take over control smoothly. Simultaneously, a surveillance handover shares radar or surface surveillance data so the new ATC unit can continuously track the aircraft and maintain separation. This combination guarantees seamless ATC service as the aircraft crosses the FIR boundary. Direct radio handover lacks a standardized data transfer framework, manual handover is prone to delays and errors, and satellite link, while useful for communications, is not the primary mechanism of FIR boundary coordination.
