What is the EFC time for arrivals after TCP time at Dinky?

The correct answer of 5 minutes for the Expected Final Approach (EFC) time after the Traffic Coordination Point (TCP) time at Dinky reflects the standard operational procedures for managing arrivals. The 5-minute timeframe provides an appropriate balance to ensure that arrivals can be sequenced effectively while maintaining safe distances between aircraft.

This duration is practical as it allows for adequate time to make necessary adjustments to landing sequences, while also ensuring that air traffic controllers have sufficient time to handle any emerging situations, such as changes in runway availability or unexpected delays. Additionally, maintaining a 5-minute EFC time assists with overall traffic flow in the terminal airspace, enabling a smooth transition from en-route to the approach phase.

Understanding this link between the TCP time and EFC time is crucial as it enhances situational awareness for controllers and ensures a safe and efficient process for arrivals.
