Is it considered a CI-Hook to continue landing if an IP or RSU calls for a go-around?

Continuing to land despite an Instructional Pilot (IP) or Regional Safety Unit (RSU) calling for a go-around is indeed considered a CI-Hook, or a critical incident hook. The term refers to actions taken that go against standard procedures or safety protocols. When an IP or RSU calls for a go-around, they are essentially indicating that the landing is not safe or not appropriate at that moment, whether due to factors like unstable approach, obstacles, or other safety issues.

By disregarding this call and continuing with the landing, a pilot not only puts themselves and others at risk but also fails to adhere to established safety policies in aviation operations. It's crucial for pilots to recognize and respect these calls from their instructors or safety units as they are made to ensure a safe operating environment.

The other options imply that there might be scenarios or specific groups of pilots (like student pilots) where this might not be a CI-Hook, which can create ambiguity and potentially unsafe practices. The correct understanding is that safety protocols must always be followed, making it clear that going against the call for a go-around is unequivocally viewed as a serious breach of protocol.
