Aerospace physiology is the study of the effects of high altitudes on the body, such as different pressures and levels of oxygen. At different altitudes the body may react in different ways, provoking more cardiac output , and producing more erythrocytes .
Illusions in aviation are caused when the brain cannot reconcile inputs from the vestibular system and visual system. The three semicircular canals, which recognize accelerations in pitch, yaw, and roll, are stimulated by angular accelerations; while the otolith organs, the saccule and utricle, are stimulated by linear accelerations.
In aviation, spatial disorientation can result in improper perception of the attitude of the aircraft, referring to the orientation of the aircraft relative to the horizon. If a pilot relies on this improper perception, this can result in inadvertent turning, ascending or descending.
The leans is a type of vestibular illusion in flight which causes spatial disorientation. The process involves the semicircular canals of the vestibular system.The semicircular canals detect angular acceleration.
The 5M model is a troubleshooting and risk-management model used for aviation safety. [1] [2] ... including the physiology and psychology of those involved, ...
He explained that, for example, the "barking dog noise" people associate with the Airbus at the end of taxiing is a result of transferring from single-engine taxiing to switching on both before ...
The first type is more common as pressure reduction from normal atmospheric pressure to a vacuum can be found in both space exploration and high-altitude aviation. Research and experience have shown that while exposure to a vacuum causes swelling, human skin is tough enough to withstand the drop of one atmosphere .
In aviation, a graveyard spiral is a type of dangerous spiral dive entered into accidentally by a pilot who is not trained or not proficient in flying in instrument meteorological conditions (IMC). [1] Other names for this phenomenon include suicide spiral, deadly spiral, death spiral and vicious spiral. [2]
