Inversion Illusion: The Inaccurate Perception of Flight Direction
Inversion illusion refers to the sensation that an aircraft is pitching or tumbling backwards, which can occur when there is an abrupt shift from a climb to straight and level flight in conditions where there is limited visual reference. This phenomenon stems from the way the human body perceives spatial orientation and can be particularly disorienting for pilots, especially those who lack experience or are not properly trained.
The confusion occurs due to the fact that the body relies on visual input and sensory cues from the inner ear to maintain a sense of balance and spatial orientation. When an aircraft makes an abrupt maneuver from climb to level flight, the body perceives this shift as a sudden movement in the opposite direction.
This false perception of movement can cause disorientation, leading the pilot to overcorrect and potentially lose control of the aircraft. To avoid inversion illusion, pilots are trained to rely on their instruments and to maintain a consistent rate of climb when transitioning to level flight.
Overall, inversion illusion is a dangerous phenomenon that pilots must be aware of and trained to overcome in order to maintain safe and accurate flight direction.
