C09 - Perceptual Errors Flashcards
Any scenario in which visual cues are absent increases the risk of ‘____’?
Vestibular Illusions.
True or False. The Vestibular System assumes that Linear Accelerations of 1G relative to the body are the effects of Gravity?
True.
The Vestibular System can only detect initial ‘____’?
Angular Accelerations.
What causes Somatogravic Illusion?
Linear Accelerations.
How does Somatogravic Illusion happen?
When there are no visual clues to correct misinterpretations.
A large forward acceleration makes you feel as if you are ‘____’?
Pitching Up.
A large deceleration makes you feel as if you are ‘____’?
Pitching Down.
What causes Somatogyral Illusion?
Semicircular Canals.
The Somatogyral Illusion is the feeling of being ‘____’ when in fact the head is still ‘____’ (2)?
- Stationary.
- Rotating.
What kind of illusion is when a pilot has a strong physical sensation that you are not in the same orientation as that shown by the Aircraft Instruments?
The Leans.
What important rules should pilot remember when experiencing the leans?
Trust you Instruments.
When turning in an Aircraft, a Pilot should avoid any head movements as this can lead to what?
Coriolis Illusion.
What is the name of the sensation of rotation occurring during flight and which is caused by multiple irritation of several Semicircular Canals at the same time?
Vertigo.
What causes Autokinetic Illusion?
When the Eye is deprived of almost all background information.
True or False Autokinetic Illusions under such conditions the light source can appear to move randomly?
True.
During Mist, Fog and Haze, object will appear ‘____’ than they actually are?
Further Away.
An upsloping runway gives the illusion that you are ‘____’ on the Approach?
High.
A downsloping runway gives the illusion that you are ‘____’ on the Approach?
Low.
When does the Block Hole Effect occur in flight?
Visual Approach at Night.
What does the Black Hole Effect result in?
Being lower than usual on Approach.
The Black Hole Effect is more pronounced on ‘____’ runways?
Short.
The Black Hole Effect is most dangerous on an ‘____’ runway?
Upsloping.
How can a Pilot overcome Spatial Disorientation?
By obtaining reliable visual references such as the True Horizon.
