What does "ESTABLISHED" indicate when used as an informative call in aviation?

The term "ESTABLISHED" in aviation communication indicates that an aircraft has reached an assigned geographic location, typically a specific point on an airway or an approach to an airport. When a pilot declares they are "established," it signifies they have successfully navigated to the intended fix or location and are in the correct position to proceed with their next navigational or procedural steps.

For example, when entering a holding pattern or executing an approach, stating "established" communicates to air traffic control and other aircraft that its position is confirmed, allowing for proper sequencing and coordination within the airspace. This understanding of positional report is critical for maintaining safety and efficiency in aviation operations.

The other choices refer to various actions within aviation operations but do not accurately represent what "ESTABLISHED" conveys in this context. For instance, initiating radar scanning procedures and launching new mission profiles pertain to different operational tasks that do not align with the specific meaning of being established at a geographic point. Similarly, beginning a landing sequence usually involves additional procedural cues that are not captured solely by the term "established."
