Study Notes
Inversion Illusion
- Abrupt transition from climbing to straight and level flight can create the sensation of tumbling backwards.
- Pilots often respond by lowering the nose to regain a stable attitude.
Coriolis Illusion
- Occurs after prolonged turning, causing the body to adapt to the motion.
- Turning the head during the turn can mislead the pilot into believing the aircraft is moving in another direction.
Elevator Illusion
- Rapid vertical acceleration, such as encountering an updraft or downdraft, can induce the perception of climbing or descending.
- Pilots may correct this illusion by adjusting the aircraft's nose position up or down.
False Horizon
- Environmental factors like sloping clouds or uneven ground lights can obscure the true horizon.
- This can mislead pilots, potentially leading to dangerous flight attitudes.
Leans
- Returning to level flight after an extended turn can create an illusion of turning in the opposite direction.
- This misperception can result in erroneous control inputs.
Autokinesis
- Fixating on a stationary light for too long may cause it to appear as if it is moving.
- This can result in disorientation and loss of heading as pilots may inadvertently follow the "moving" light.
Graveyard Spiral
- During a prolonged turn, pilots may feel as if they are in level flight when they are not.
- When returning to level, the sensation of turning in the opposite direction can cause pilots to re-enter the original turn, leading to altitude loss and tighter turns due to excessive yoke pull.
Somatogravic Illusion
- Rapid acceleration can mimic the feeling of tilting the head back, creating the illusion of a nose-up attitude.
- Pilots may instinctively push the nose down to correct this perceived ascent; this illusion also occurs during deceleration.
