In the case of an unplanned passenger manifest change, what is the necessary action?

In the context of an unplanned change to the passenger manifest, notifying C2 (Command and Control) is essential because it ensures that the appropriate authorities are aware of the changes to ensure safety and operational efficiency. C2 plays a critical role in managing resources and responding to any implications that may arise from changes in the passenger load, such as security considerations, logistics, and flight safety assessments.

Ensuring these authorities are informed is crucial for situational awareness and operational integrity, particularly in a military context where missions may involve sensitive or strategic elements. Notifying C2 allows for the adequate management of the flight's operational status and risk assessment following changes in passenger dynamics.

Immediate passenger notification before takeoff may not be feasible or necessary, as changes can be assessed and managed within the operational framework. Disregarding changes could lead to serious safety and compliance issues, while altering flight plan details after departure would generally not be appropriate without due consultation and authorization. Therefore, the correct action aligns with standard protocol to maintain safety and streamline operations.
