When should a strip be removed from its bay?

The appropriate time to remove a strip from its bay is when it is no longer needed for control purposes. This is based on the operational need for accurate and up-to-date information to maintain effective air traffic control. Strips are essential for providing real-time data regarding aircraft movements, and once the information becomes obsolete because a flight has completed its role in the airspace or is no longer under the controller's jurisdiction, it is considered unnecessary.

This practice ensures that the workflow remains organized and that controllers are not overwhelmed by outdated information. While criteria such as the accuracy of the information (an element highlighted in the first choice) or the flight status (post-landing or after reaching cruising altitude) can be relevant, they do not fundamentally address the necessity of the information for ongoing control. Thus, the central tenet of maintaining safety and order in air traffic management hinges on the timeliness and relevance of the strips in use.
