Somatogravic Illusion
Definition
A vestibular illusion during rapid acceleration (like takeoff) where the pilot senses a pitch-up attitude and may push the nose down. During deceleration, the opposite occurs. Dangerous during night or IMC takeoffs.
Why Somatogravic Illusion Matters for Pilots
Understanding Somatogravic Illusion is important for pilot certification exams and safe flight operations. This concept appears on FAA and EASA knowledge tests, and examiners may ask about it during oral checkrides. A thorough understanding of Somatogravic Illusion helps you make better decisions in the cockpit.
Exam Tip
This concept is commonly tested in human-factors-related questions on FAA and EASA exams. Make sure you can explain Somatogravic Illusion in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
