Aeromedical Factors Flashcards
What are the 7 types of Spatial Disorientations
“ICEFLAGS”
I - Inversion
C - Coriolis
E - Elevator
F - False Horizon
L - Leans
A - Autokinesis
G - Graveyard Spiral/Spin
S - Somatogravic
Inversion
feels like you’re tumbling backwards from pitching down too quickly
Coriolis
picking up your pen during a steep turn, making you disorientated and feeling out of balance
Elevator
updrafts “feels” like you need to pitch forward
downdrafts “feels” like you need to pitch up
False Horizon
clouds or city lights giving you a false horizon
Leans
“feels” like you’re straight n level but you’re turning
Autokinesis
dark room “white flash” and you still see that light moving, same with flying you see that light out in the distance and all of a sudden you use it as a reference which could be dangerous
Graveyard Spiral/Spin
Spiral: airspeed is fast, feels like you’re straight & level but you’re actually spiraling downwards
Spin: stalled condition, airspeed is slow, you think you’re descending, causing you to pull back
Somatogravic
rapid forward acceleration, making you feel like you’re pitching up, so you pitch down which is wrong
Explain how the vestibular affects spatial disorientation
Cupula “hairs” in your semicircular canals. You have 3 in each ear, filled with fluid. One sense pitch, another senses roll, and the last sense yaw. Whenever you’re body is positioned differently, the hair follows and also has an opposite reaction depending how fast you move.
