What is the purpose of scanning 60 degrees each way and 10 degrees up and down?

The purpose of scanning 60 degrees each way and 10 degrees up and down is primarily associated with the see and avoid doctrine. This doctrine is fundamental in aviation, particularly in scenarios involving visual flight. It emphasizes the need for pilots to maintain visual separation from other aircraft and obstacles in the airspace.

By scanning this prescribed field of view, pilots can enhance their situational awareness, ensuring they can detect and respond to potential conflicts with other aircraft. The wide lateral scan of 60 degrees allows pilots to hunt for nearby traffic on either side, while the 10-degree vertical scan helps identify altitude differences that could be crucial for avoiding collisions. This practice is especially vital in uncontrolled airspace where air traffic control may not provide guidance, allowing pilots to take personal responsibility for their safety and the safety of those around them. The focus on visual scanning is a core component of maintaining a safe flying environment which is integral to effective air navigation and accident prevention.
