What action is required before a pilot can depart if restricted by an EDCT?

The correct course of action before a pilot can depart when restricted by anEDCT (Expected Departure Clearance Time) is to ensure compliance with the EDCT. This means the pilot must be aware of the specific time assigned for departure that will help manage air traffic flow, especially during periods of congestion. Complying with the EDCT ensures that the aircraft departs at a time that aligns with the air traffic control (ATC) plan, helping to minimize delays and maintain safety in the airspace.

While confirming weather conditions and checking for other aircraft on the runway are important safety measures, they are not specific actions directly associated with the requirement of an EDCT. Therefore, ensuring compliance with the EDCT is the primary responsibility that must be met before taxiing for departure.
