What could result from failing to establish visual reference during approach?

Failing to establish a visual reference during the approach can lead to a go-around maneuver. Visual references are crucial for pilots to determine their altitude, alignment with the runway, and overall situational awareness as they prepare to land. Without visual cues, a pilot may not have adequate information to make a safe landing decision, which could result in being unsure about their approach or actual landing position. Therefore, executing a go-around becomes the safest and most prudent course of action, allowing the pilot to circle back to make another attempt at landing when conditions have improved or visual references are regained. This decision prioritizes safety and allows for better assessment and alignment with the runway.
