What action is necessary for pilots during taxiing?

During taxiing, effective communication with air traffic control is crucial for pilots to ensure the safe movement of the aircraft on the ground. This process involves receiving guidance on routes, potential hold positions, and clearance for takeoff. Maintaining constant updates with air traffic control helps pilots navigate properly, prevents runway incursions, and avoids collisions with other aircraft or ground vehicles.

The other options may relate to broader aspects of flight operations but are not relevant during the taxiing phase. For example, conducting a safety briefing pertains to passenger awareness and preparation for the flight, which typically occurs before takeoff. Minimizing fuel consumption and adjusting in-flight entertainment are considerations that come into play during different phases of the flight operation but are not actions that need to be taken during taxiing. Thus, communication with air traffic control is the necessary and critical action for pilots at this stage.
