When an aircraft is holding at RINKY and requests to divert from KMLU to KPBF, what should the student do?

When an aircraft holding at RINKY requests to divert from KMLU to KPBF, the appropriate action involves amending the route and checking for PVD (Pilot Verified Departure) needs. This step is crucial as it ensures that the aircraft is provided with a revised route that allows for safe and efficient navigation to the new destination, KPBF.

In addition, checking for PVD needs is also important as it involves verifying whether the aircraft requires any particular services or information prior to executing the diversion. This can help prevent any potential issues that might arise from the change in route or destination, ensuring that air traffic control maintains safety and communication throughout the process.

Issuing a new flight plan immediately would typically follow after amending the route but requires the initial steps of coordination and checking. Coordination with another sector would usually be handled later in the process once the new route is established, ensuring all parties are informed. Notifying the original destination's airport, while necessary, is typically part of the obligations of air traffic control once the diversion is confirmed, not the immediate response to the diversion request. Thus, amending the route and checking for PVD needs is the most critical and immediate action in this scenario.
