Which illusion causes misperception of height or depth due to perspective cues?

• A. False Horizon
• B. Height/Depth Illusion
• C. Confusion w/ Ground Lights
• D. Structural Illusion

Answer: (B)

Height/Depth Illusion happens when perspective cues in the visual scene distort how we judge distance, height, or depth. In flight, the eyes rely on cues like the apparent size of objects, texture and shadow gradients, and the angle of lines on the ground to gauge altitude. When these cues lead you to interpret distance or height inaccurately, you experience a misperception of height or depth. This is the classic scenario for this illusion: the scene’s perspective tricks your sense of how high you actually are above the ground. The other options describe different visual misperceptions. False Horizon is about misidentifying the horizon line itself, Confusion with Ground Lights involves misjudging runway or terrain cues from lights at night, and Structural Illusion involves illusions caused by nearby tall structures. Each can affect perception in flight, but they aren’t defined primarily by misinterpretation of height or depth due to perspective cues in the scene.
