What type of messages should pilots transmit to air traffic control?

Pilots should transmit messages that are necessary for air traffic control as these communications are crucial for maintaining safe and efficient operations within controlled airspace. This encompasses key information such as position reports, intentions regarding altitude changes, requests for clearance, and updates on any changes to flight plans. By communicating relevant and structured information, pilots help air traffic controllers ensure the safety of all aircraft in their jurisdiction, facilitate effective traffic management, and ensure compliance with regulations.

Other types of messages, such as personal experiences or informal updates about the flight, do not contribute to the operational standards required for air traffic control. Additionally, messages from ground staff are typically relayed to pilots through formal communication channels rather than directly from the pilots themselves. Therefore, it is essential for pilots to focus on sending necessary and pertinent messages to facilitate safe air traffic operations.
