If a delay is longer than expected, what action should you take?

When faced with a delay that exceeds expectations, issuing a new Expected Final Clearance (EFC) prior to its expiration is crucial. The EFC is essentially a timeline that helps coordinate the flow of air traffic. By providing an updated EFC, you communicate to air traffic control, as well as other relevant parties, that there has been a change in the expected timing of the flight's progression.

This action is essential because it allows air traffic control to manage airspace more efficiently. It ensures that all parties are aware of the new timeline, which helps to optimize traffic flow and reduce the chances of further delays or confusion.

The other actions—such as notifying air traffic control, canceling the flight plan, or requesting an alternate holding pattern—are typically not necessary if the only issue at hand is an extended delay. Rather, these options may be more appropriate in more severe situations or when other operational issues arise that require immediate attention. Thus, updating the EFC is a standard and proactive measure to maintain clarity and cooperation within the air traffic management system during unexpected delays.
