Which crew member, similar to the Ground Security Coordinator, is empowered to evaluate and resolve security-related scenarios that occur while airborne as an additional responsibility of the Captain?

• A. Inflight Crewmember
• B. Ground Security Coordinator (GSC)
• C. Inflight Security Coordinator (ISC)
• D. Jumpseat (JS)

Answer: (C)

The key idea is that security leadership shifts from ground operations to the aircraft itself when you’re in the air. The person designated to evaluate and respond to security-related situations during flight, as an extra duty of the Captain, is the Inflight Security Coordinator. This role mirrors the Ground Security Coordinator but operates on board the airplane. The ISC is a trained inflight crewmember who can assess threats, decide on immediate actions, and coordinate with the Captain to apply security procedures—such as restricting access, notifying authorities, or initiating other in-flight security measures—while the Captain retains overall command. The Ground Security Coordinator handles security on the ground with authorities; a general inflight crew member or a jumpseat location isn’t assigned the formal authority to resolve in-flight security scenarios. That makes the Inflight Security Coordinator the correct selection.
