What defines "Radar Contact" in air traffic control?

"Radar Contact" specifically refers to the successful identification and tracking of an aircraft by air traffic control using radar systems. When an air traffic controller establishes radar contact, it means that the aircraft has been positively identified on the radar display and is being monitored. This identification is crucial during handoffs between different controllers or sectors, ensuring that aircraft can be managed safely and efficiently as they transition through various airspace sectors.

Correctly identifying an aircraft during a handoff is essential for maintaining safety and avoiding potential conflicts with other aircraft. It provides the next controller with vital information about the flight's current position, altitude, and intentions, thus enabling them to provide appropriate guidance. This process is fundamental to air traffic management, as it allows for continuous and effective monitoring of aircraft throughout their flight paths.

The other choices do not accurately capture the essence of what "Radar Contact" means within air traffic control. For instance, one option mentions loss of contact, which is the opposite of what "Radar Contact" signifies, while another refers to tracking altitude, which is just one aspect of radar use but not the defining feature of establishing radar contact.
