When approaching to land on a runway served by a 2-bar Visual Approach Slope Indicator (VASI), understanding the color indications is crucial for safely aligning with the glide path. The correct interpretation of the VASI lights provides important visual cues to the pilot regarding their position relative to the desired glide path.

In this case, the correct answer highlights that when a pilot is departing to the high side of the glide path, the far bars will change from red to white. This occurs because when you are too high on the glide path, the near light will typically show red while the far light will show white, indicating that the pilot is above the correct glide slope. The transition of the far bar from red to white signifies that the pilot is moving away from the ideal descent profile, suggesting the need to descend to meet the glide path properly.

Understanding these indications helps pilots make necessary adjustments during their approach to ensure a safe landing. The inability to interpret these signals accurately could lead to an unstable approach, emphasizing the importance of knowing how the VASI indicators operate.
