Who does the CSA or GSC disclose the identities or seat locations of all armed individuals on the aircraft to?

The correct answer highlights the importance of communication and security protocols on an aircraft. The Captain in Command (PIC) and the Flight Attendant Manager (FAM) team leader are responsible for the safety and security of all those on board, including awareness of armed individuals.

Disclosing the identities or seat locations of armed individuals to these key personnel allows them to implement necessary safety protocols and manage potential security threats. This information needs to be shared with individuals who are directly responsible for the operational safety of the flight, ensuring that they are prepared to respond appropriately if needed.

The remaining options do not align with the security procedures in place. For example, while flight attendants and cabin personnel play significant roles in passenger safety, they are not designated as the primary recipients of this critical security information. Moreover, disclosing this information to all onboard passengers could create unnecessary panic and compromise the safety and security of the operation.
