Why is visual clearance important during TFO?

Visual clearance is fundamental during Terrain Flight Operations (TFO) because it significantly enhances a pilot's situational awareness and ability to navigate safely. In environments where terrain and obstacles are prevalent, visual clearance directly allows pilots to identify and avoid these challenges, which can include natural features like mountains or man-made structures.

By maintaining visual clearance, pilots can make real-time adjustments to their flight path based on what they see, rather than relying solely on instruments. This ability to visually assess the surroundings is particularly vital in low-altitude operations where the risk of collision with obstacles is heightened.

While remembering flight paths and the functionality of navigation systems are important aspects of operating an aircraft, they do not replace the necessity for visual inspection and situational awareness. Visual clearance is not restricted to takeoff and landing phases, as it remains crucial during all phases of flight where terrain might pose a risk. Thus, visual clearance fundamentally supports safety and helps mitigate the chances of accidents due to terrain-related obstacles.
