What can be a critical factor in preventing a graveyard spiral?

Understanding spatial disorientation is crucial in preventing a graveyard spiral, as it addresses the pilot's awareness of their orientation relative to the Earth's surface and their aircraft's attitude. In scenarios where pilots enter a prolonged turn, they may not realize they are in a descending spiral due to the visual cues that can be misleading when flying in conditions where horizon references are obscured, such as in low visibility or at night.

By comprehensively understanding spatial disorientation, pilots can recognize when they are experiencing incorrect perceptions of their flight path and take corrective measures before the situation escalates into a graveyard spiral. This awareness is particularly important because the graveyard spiral can occur when the pilot has a false sense of comfort or control, believing they are straight and level when they are actually descending. Recognizing these cues and understanding one's orientation are essential in maintaining proper flight control and preventing such dangerous situations.

The other options, while beneficial within the context of aviation safety, do not directly address the specific phenomenon of spatial disorientation related to graveyard spirals. Regular maintenance checks and improving autopilot functions contribute to overall aircraft safety and operational efficiency but do not specifically mitigate the risks posed by spatial awareness in flight. Expanding passenger capacity is unrelated to the pilot's ability to
