What is the purpose of a SIA?

The purpose of a Situation Information Awareness (SIA) display is to show the status of position-related equipment and operational conditions. It is a crucial tool for controllers as it provides real-time data concerning both the aircraft's status and the surrounding environment. This information allows controllers to make informed decisions regarding traffic management and safety, ensuring that they have a complete picture of operational conditions. By being aware of the status of equipment related to navigation and air traffic management, controllers can enhance their situational awareness, leading to more effective and safer air traffic control operations.

While navigation instructions, air traffic control procedures, and information about restricted airspace are also important elements of air traffic management, they do not encapsulate the specific purpose of an SIA display, which is primarily focused on providing immediate situational updates regarding equipment and operational status.
