Transmitting only necessary messages for air traffic control is crucial for contributing to air safety. This principle underscores the importance of clear and concise communication in a high-stakes environment, such as air traffic control. Each message relayed to pilots contains vital information that can directly impact the safety of an aircraft's operation, including instructions, alerts, and changes in flight plans.

By focusing on messages that are essential for safety, controllers help ensure that pilots receive critical information without the distraction of extraneous communications. This focus on safety not only facilitates better situational awareness for pilots but also contributes to maintaining the overall safety of the airspace system.

While operational efficiency, standard procedures, and minimizing frequency congestion are all valid considerations in air traffic control, they serve to support the overarching goal of enhancing safety in aviation operations. Prioritizing safety ensures that the primary responsibility of air traffic controllers is met, providing a secure environment for all flights.
