What protocol should a pilot follow when departing from a controlled airport?

When departing from a controlled airport, obtaining clearance from Air Traffic Control (ATC) before taxiing is essential for ensuring safety and effective management of air traffic. This process helps to establish a clear communication line between the pilot and ATC, allowing the controller to provide necessary instructions, including taxi routes and departure sequencing.

This protocol is critical as it ensures that all operations at a controlled airport are carefully coordinated. ATC has the responsibility to manage aircraft movements on the ground and in the airspace surrounding the airport. By requiring pilots to obtain clearance before taxiing, ATC can provide updates on runway availability, other aircraft movements, and any potential hazards, which all contribute to safer operations.

Failing to obtain clearance can lead to dangerous situations, including runway incursions, which can cause accidents. Therefore, following this established protocol is vital for maintaining safety while operating in busy airspace and on the ground at an airport.
