Grüner Star – Verengung des Gesichtsfelds durch erhöhten Augeninnendruck

Was ist Cataract?

Grauer Star – Trübung der Linse, z. B. durch Alter, Trauma oder Vererbung

What type of acceleration is detected by the semicircular canals?

Angular accelerations
Which two structures detect linear acceleration?

Utricle and saccule

What are otoliths?

Small crystals that assist in sensing gravity and linear acceleration

Which system works with the visual system to support spatial orientation?

Vestibular system

What is the main function of the semicircular canals?

Detect head rotation in three planes
Which structures detect angular acceleration?

Semicircular canals

Which two structures perceive linear acceleration?

Utricle and saccule

What do the otoliths help detect?

Gravity and linear acceleration

Which systems support spatial orientation?

Vestibular and visual systems
What is the illusion called where a pilot thinks they are in level flight after a prolonged spin?

Graveyard spin

Which illusion occurs when a slow roll is below the perception threshold and corrected abruptly?

The leans

Which illusion involves a head movement during a constant turn and is considered most dangerous?

Coriolis illusion

How many seconds can a pilot maintain control without instruments according to FAA research?

170 seconds

Which type of spatial disorientation is most dangerous and not perceived by the pilot?

Type 1 unrecognized

Which type of spatial disorientation is when the pilot notices the illusion but cannot recover?

Type 2 recognized

Which type of spatial disorientation leads to complete incapacitation due to strong illusion?

Type 3 incapacitating
