flight instruments. As pilots gain proficiency in instrument flying, they become less susceptible to these illusions and their effects. Optical Illusions Of the senses, vision is the most important for safe flight. However, various terrain features and atmospheric conditions ... create optical illusions. These illusions are primarily associated with landing. Since pilots must transition from reliance on instruments to visual cues outside the flight deck for landing at the end of an instrument approach, it is imperative that they…
