When diverting aircraft, why might a new strip be necessary?

Using a new strip when diverting aircraft is essential because it often indicates a change in operational responsibility and sector control. When an aircraft diverts to a different sector, the current controller may not have the necessary information or authority to manage the flight's continued operations. This necessitates a new strip to ensure that the incoming receiving sector has all relevant data, including the updated flight path, intentions, and any pertinent notes regarding the aircraft's status and situation.

In addition, a new strip helps maintain accurate flight records and facilitates the handoff process between sectors. It allows the new controller to have an organized view of the flight's trajectory and requirements, which promotes safety and efficiency in air traffic management. This practice aligns with standard operating procedures to enhance coordination among controllers and improve communication regarding flight status during diversions.
