When flying in controlled airspace, what is required of pilots?

In controlled airspace, maintaining communication with air traffic control is essential for ensuring safe and orderly air traffic operations. Pilots are required to establish and maintain two-way radio communication with ATC, which allows for the exchange of crucial information regarding the aircraft's position, intentions, and any instructions from air traffic controllers.

This requirement helps manage the flow of air traffic, especially in busy airspaces, and aids in maintaining safe distances between various aircraft. It also ensures that pilots have the latest updates about weather conditions, air traffic, and any restrictions that may affect their flight path. Consequently, this communication is vital for enhancing safety and efficiency in controlled airspace operations.

The other options, while they may reflect certain aspects of flying, do not encompass the primary requirement of pilots in controlled airspace as directly and broadly as maintaining communication with ATC does.
