If a mismatch (MISM) is observed during a handoff, what must the student do?

When a mismatch (MISM) occurs during a handoff, the appropriate response is to inform the Supervisor about each instance of the mismatch. This step is critical as it ensures that the supervising personnel are aware of the issue, enabling them to assess the situation accurately and make necessary decisions to ensure safety and efficiency in operations.

By reporting the mismatch, the student allows for proper oversight and coordination, which is essential in maintaining situational awareness and ensuring that any systemic issues contributing to the mismatches can be addressed effectively. This action also fosters communication within the team, as supervisors may provide further instruction or guidance on managing the situation.

The other responses do not align with standard operating procedures, as ignoring a mismatch could lead to safety risks, attempting to correct it independently may lead to confusion without proper oversight, and notifying the pilot directly without going through the established chain of command may not comply with communication protocols, potentially putting flight operations at risk.
