When must a visual scan be completed in relation to low approaches?

Completing a visual scan before initiating a low approach is crucial for several reasons. This scan helps ensure that the pilot has situational awareness of the airspace environment, including the location of other aircraft, obstacles, and the overall status of the landing area. By performing this scan prior to initiating the low approach, the pilot can make informed decisions regarding their flight path and ensure that they maintain safety and compliance with visual flight rules (VFR) or any applicable operating procedures. This proactive approach plays a vital role in avoiding potential conflicts and enhancing overall flight safety during low approaches when visibility and awareness are critical.
