Should the presence of an IFSO be disclosed to an ACPO on board?

The reasoning behind the choice that the presence of an IFSO (In-Flight Security Officer) should be regarded as confidential is rooted in the security protocols and procedures that govern aviation safety. The role of the IFSO is to maintain the security and safety of the flight, often dealing with sensitive situations that can impact the overall safety of passengers and crew.

By keeping the IFSO's presence confidential, it ensures that potential disruptive individuals or situations do not become aware of the officer's identification, which could compromise the security measures in place. This confidentiality is crucial as it allows the IFSO to perform their duties effectively without any external interference or escalation due to their presence being known.

In contrast, the other options suggest varying levels of communication between the IFSO and ACPO (Air Canada Protection Officer), but these do not align with the standard protocols that prioritize security and confidentiality on board an aircraft. Revealing the IFSO's identity can create unnecessary risks, which is why confidentiality is maintained as a priority.
