In runway width illusion, what perception and consequent action are described?

• A. Wide runway: feel higher, will fly lower
• B. Wide runway: feel lower, will fly higher
• C. Narrow runway: feel lower, will fly higher
• D. Narrow runway: feel higher, will fly lower

Answer: (B)

Runway width illusion shows how depth cues affect altitude perception during an approach. When the runway is wide, the cues can make you feel that you are lower than you actually are. As a result, you tend to raise the nose to climb back up to the expected glide path, causing you to fly higher than planned. This matches the described perception and action: feeling lower than actual altitude and then climbing, leading to a higher flight path. In contrast, a narrow runway tends to make you feel higher than you are, prompting a descent and a lower flight path.
