During taxiing, what should pilots confirm regarding communication?

During taxiing, it is vital for pilots to confirm that they have received clearance from Air Traffic Control. This confirmation ensures that the pilots are authorized to proceed with their taxiing operations, adhering to the specific routes and any instructions provided by ATC. Clearance from ATC is essential for maintaining safety and efficiency at the airport, as it helps prevent collisions and misunderstandings between various aircraft and ground traffic.

While other aspects such as inter-pilot agreement, weather updates, and fuel levels are important for overall flight safety and planning, they are not the primary focus during the taxiing phase. The immediate need for a clear and specific authorization from ATC directly impacts the safe movement of the aircraft on the ground.
