When should EFC times be updated?

Updating Estimated Fuel Consumption (EFC) times before they expire is crucial for maintaining operational efficiency and safety in aviation. This proactive approach ensures that flight crews have the most current information on fuel needs and consumption rates, allowing for timely adjustments to operational plans.

By updating EFC times before expiration, pilots can make informed decisions regarding fuel management and flight continuation, which is essential in situations where changes in flight paths, delays, or other factors may affect fuel consumption. This practice helps avoid last-minute changes that could lead to a decrease in situational awareness or potential safety risks.

Maintaining up-to-date EFC information allows for better planning and coordination with air traffic control and ground services, which ultimately supports the overall success and safety of the flight operation.
