What about using “Visual Course Guidance” or see-and-avoid procedures?
AC 120-91 allows for “Visual Course Guidance” under specific conditions. This includes maintaining 300 ft lateral clearance from known obstacles or 35 ft vertical clearance within that 300 ft zone. However, this assumes the operator has identified and evaluated all relevant obstacles.
At complex airports like Eagle, where APG tracks over 3,000 published obstacles plus significant terrain, visual avoidance becomes highly impractical without extensive analysis. In such environments, relying on see-and-avoid is not recommended.
