Which of the following is a condition for automatic track initiation for a flight?

Automatic track initiation is a process in radar systems where the system automatically begins to track an aircraft once certain conditions are met. A stored flight plan is essential for this process because it allows the radar system to recognize and anticipate the aircraft's intended route and behavior. When a flight plan is stored, the radar can compare the real-time data it receives with the flight path, facilitating more accurate tracking and communication.

Without a stored flight plan, the radar system lacks vital information about the aircraft's intended course, making it challenging to initiate accurate tracking automatically. The other factors, such as altitude, proximity to an airport, or the presence of a pilot, may influence tracking capabilities but do not serve as primary conditions for automatic track initiation. A stored flight plan is crucial because it integrates operational data necessary for seamless tracking and ensures that air traffic controllers can maintain situational awareness effectively.
