Final answer:
Category II ERCCs are enacted in aviation when the number of personnel deplaning and boarding exceeds a certain threshold, which requires a coordinated, timely response.
Step-by-step explanation:
The question pertains to Category II Emergency Response Control Center (ERCC) procedures, likely in the context of aviation operations or military protocol. Category II ERCCs will be performed when the total personnel deplaning, plus those boarding the aircraft, exceeds a specific number.
This threshold number is not provided in the question and would typically be found in an operational manual or regulations specific to the organization or airport. Category II ERCCs require coordinated efforts which include communication, deployment of personnel, and equipment readiness, and will be accomplished in an organized, timely, and efficient manner.
Unfortunately, without the specific numeric threshold or the manual in question, a complete answer cannot be provided. However, it's important for personnel involved in such operations to be familiar with their specific protocol.
