What is the impact of refraction errors on pilot perception?

• A. It causes you to appear higher than you really are
• B. It causes you to appear lower than you really are
• C. It has no impact on visual perception
• D. It improves altitude awareness

Answer: (B)

Refraction errors occur when light bends as it passes through different layers of the atmosphere, particularly during conditions of temperature inversion or when flying at low altitudes. The result of this bending can lead to visual distortions, which can significantly affect a pilot’s perception of altitude. When a pilot experiences refraction errors, it can make them perceive their aircraft to be lower than it actually is. This misperception is especially critical during approach and landing phases, where accurate altitude awareness is essential for safety. If a pilot believes they are lower than they are due to refraction effects, they may inadvertently descend too quickly or initiate a premature landing, increasing the risk of accidents. Understanding the phenomenon of refraction is crucial for pilots to maintain proper altitude awareness and make informed decisions based on accurate perceptions of their aircraft's position relative to the ground.
