What does "Radar Contact" signify for IFR operations?

The phrase "Radar Contact" in the context of IFR operations indicates that Air Traffic Control (ATC) is able to visually track the aircraft's position using radar. This status is crucial for flight operations, as it confirms to both the pilot and ATC that the aircraft's location is known and monitored, enabling the safe management of air traffic. When ATC establishes radar contact with an aircraft, they can provide effective guidance, traffic advisories, and pertinent instructions based on the aircraft's current position and flight plan.

The significance of this status lies in its implications for the safety and efficiency of air navigation. By confirming radar contact, ATC can maintain situational awareness, which is essential for avoiding potential collisions and ensuring safe separation between aircraft, especially in busy airspaces.
