At which location does the STELA.STELA1 arrival begin?

The STELA.STELA1 arrival begins at the CANAN intersection, making it the correct answer. This approach is part of the Standard Terminal Arrival Route designed to facilitate arrivals into a particular airport, and identifying its starting point is crucial for both pilots and air traffic controllers to ensure safe and efficient traffic management.

The CANAN intersection serves as a fixed point in space that allows incoming flights to transition from en-route phases to the terminal area's air traffic control system. Understanding this waypoint helps in planning and executing a proper approach, as it marks the commencement of the procedures that subsequently guide the aircraft towards landing. Proper adherence to these routes is vital for maintaining airspace order and ensuring that all aircraft are correctly sequenced for landing.

Recognizing the significance of specific waypoints in arrival procedures is key to navigating air traffic effectively, as each intersection has unique roles in various arrivals into airports. Students studying arrival routes must recall such specific starting points to prepare for real-world navigation scenarios accurately.
