The concept involves a pilot’s ability to maintain a safe distance from other aircraft, relying solely on what they can see. This contrasts with procedural methods that utilize radar and air traffic control instructions to ensure spacing. An example includes a pilot visually confirming the position of another aircraft during approach, allowing them to adjust their own flight path without explicit ATC direction, within certain regulatory constraints.
Its implementation can significantly enhance airspace efficiency and reduce controller workload, particularly in visual meteorological conditions (VMC). Historically, this technique was a primary means of air traffic management. While technology has advanced, the fundamental principle remains a vital skill for pilots and a valuable tool for air traffic controllers, contributing to overall safety and operational flexibility. It also allows for expedited handling of aircraft, improving flow and reducing delays when conditions permit.
