In an aircrew with multiple crews, what is true about ICS nets?

• A. All nets are monitored separately with no overlap
• B. There is always at least one net monitored by both pilots and tactical crew
• C. ICS nets are only used on the ground
• D. There is no dedicated ICS net for crew communications

Answer: (B)

In multi-crew air operations, the intercommunications system is designed so that at least one net is monitored by both the pilots and the tactical crew. This shared channel lets critical information, callouts, and instructions be heard by everyone who needs to respond, ensuring coordinated actions and faster acknowledgement of changes in the situation. While there are separate nets for different roles to reduce unnecessary chatter, the overlap on a common net is what keeps the crew connected and prevents important messages from being missed. ICS nets are used during flight as well as on the ground, and there is typically a designated crew communications net to support cross-crew coordination.
