Who is referred to as the ISC in aviation?

The term ISC in aviation stands for Inflight Security Coordinator. This role is crucial for ensuring the safety and security of passengers and crew during a flight. The Inflight Security Coordinator is responsible for monitoring any security incidents that may occur on board and taking appropriate action, which can include coordinating with ground security personnel and managing communication with the flight crew regarding potential threats. This person's role is vital in maintaining a secure environment in the cabin, particularly in today's aviation landscape where security is a top priority.

In contrast, the other options do not specifically relate to the role defined in aviation security. While "International Security Coordinator" might suggest a role focused on broader security policies across international boundaries, it does not pertain to in-flight situations. "Incorporated Safety Coordinator" might imply a general safety role but is not an established title in aviation. Lastly, "Intended Service Coordinator" does not align with any recognized role in aviation security or operations. Each of those options misses the specificity and context of the responsibilities handled by an Inflight Security Coordinator.
