#1
Which of the following best describes the concept of visual illusions in aviation?
They are phenomena that distort perception and can potentially lead to errors in judgment or decision-making during flight.
ExplanationVisual illusions in aviation distort perception, potentially leading to errors during flight.
#2
What is the primary factor contributing to visual illusions in aviation?
Environmental factors
ExplanationEnvironmental factors are the primary contributors to visual illusions in aviation.
#3
Which factor can exacerbate visual illusions during flight?
Alcohol consumption
ExplanationAlcohol consumption can exacerbate visual illusions during flight.
#4
Which factor can significantly contribute to the occurrence of visual illusions during flight?
Low visibility
ExplanationLow visibility significantly contributes to visual illusions during flight.
#5
Which type of visual illusion is caused by the disorientation of a pilot due to the lack of external visual references, often experienced in conditions like fog or clouds?
False horizon
ExplanationFalse horizon illusion occurs due to disorientation from lack of external references.
#6
What is the 'graveyard spiral' illusion?
An illusion where the pilot perceives the aircraft to be in level flight when it is actually in a descending turn.
ExplanationGraveyard spiral illusion: Pilot perceives level flight, but aircraft is actually in a descending turn.
#7
What is the 'black hole approach' illusion?
An illusion where the runway appears much shorter than it actually is, leading to premature descent.
ExplanationBlack hole approach illusion: Runway appears shorter, leading to premature descent.
#8
Which visual illusion is caused by the pilot's inability to differentiate between the ground and the sky, often leading to loss of orientation?
False horizon
ExplanationFalse horizon illusion: Pilot confuses ground and sky, leading to orientation loss.
#9
What is the 'crater illusion' in aviation?
An illusion where the aircraft appears to be at a higher altitude than it actually is.
ExplanationCrater illusion: Aircraft appears higher than actual altitude.
#10
What visual illusion may occur when landing on a runway surrounded by featureless terrain, such as water or snow?
Height-velocity illusion
ExplanationHeight-velocity illusion may occur when landing on featureless terrain.
#11
In which situation might a pilot experience the 'leans' illusion?
After a prolonged period of flying straight and level
ExplanationThe 'leans' illusion occurs after a prolonged period of straight and level flight.
#12
What is the 'teapot effect' illusion?
An optical illusion occurring when viewing objects with sharp angles or edges against a featureless background.
ExplanationTeapot effect illusion: Sharp-edged objects against featureless background.
#13
Which type of visual illusion is associated with the misinterpretation of ground lights or celestial lights, causing disorientation?
Autokinesis
ExplanationAutokinesis illusion is associated with misinterpreting ground or celestial lights.
#14
Which visual illusion can occur when a pilot fixates on a single point during a prolonged turn?
Coriolis illusion
ExplanationCoriolis illusion occurs when fixating on a single point during prolonged turns.
