What happens when a pilot relies solely on body signals to interpret flight attitude?

1. Increases safety.

2. Enhances spatial awareness.

3. May lead to spatial disorientation.

4. Reduces the need for instruments.

The correct answer is: May lead to spatial disorientation.

Relying solely on body signals to interpret flight attitude can lead to spatial disorientation because our body's sensory systems do not always provide accurate information in the context of flight. The human body relies on visual cues, the vestibular system, and proprioception to understand orientation and movement. However, during flight, especially in conditions with poor visibility or during maneuvers that may cause sensations that the body misinterprets (like during turbulence or turns), signals from these systems can become misleading. For instance, a pilot might feel like they are in a straight climb when the aircraft is actually in a turn, particularly in a situation where there are no external visual references. This misperception can lead to inappropriate control inputs, potentially resulting in dangerous situations, such as unintentional altitude loss or a loss of control of the aircraft. Therefore, it is critical that pilots rely on instruments, which provide objective data about the aircraft's attitude and performance, to mitigate the risks associated with spatial disorientation.
