#1
Which of the following best describes the concept of visual illusions in aviation?
They rarely occur and are insignificant in flight operations.
They are phenomena that distort perception and can potentially lead to errors in judgment or decision-making during flight.
They are only experienced by pilots with vision impairments.
They are completely preventable with proper training and experience.
#2
What is the primary factor contributing to visual illusions in aviation?
Pilot's inexperience
Lack of sleep
Environmental factors
Engine malfunction
#3
Which factor can exacerbate visual illusions during flight?
Flying at high altitudes
Clear weather conditions
Good pilot training
Alcohol consumption
#4
Which factor can significantly contribute to the occurrence of visual illusions during flight?
High altitude
Daytime flying
Low visibility
Pilot's experience
#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?
Flicker vertigo
Inversion illusion
False horizon
Autokinetic illusion
#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.
An optical illusion caused by bright lights on the ground during night flying.
A phenomenon where the pilot feels the aircraft is spinning when it's actually in straight-and-level flight.
A disorientation caused by rapid acceleration or deceleration.
#7
What is the 'black hole approach' illusion?
An illusion where the runway appears much shorter than it actually is, leading to premature descent.
An optical illusion experienced during night flying caused by the absence of visual cues.
A phenomenon where the runway lights appear to form a 'black hole' due to intense concentration during landing.
An illusion where the aircraft appears to be climbing when it is actually descending.
#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?
Flicker vertigo
False horizon
Autokinetic illusion
Elevator illusion
#9
What is the 'crater illusion' in aviation?
An illusion where the aircraft appears to be at a higher altitude than it actually is.
A visual distortion caused by flying over mountainous terrain.
An optical illusion experienced when approaching an airport surrounded by flat terrain.
An illusion where the runway seems to be significantly wider than it is.
#10
What visual illusion may occur when landing on a runway surrounded by featureless terrain, such as water or snow?
Flicker vertigo
Elevator illusion
Featureless terrain illusion
Height-velocity illusion
#11
In which situation might a pilot experience the 'leans' illusion?
During a steep bank turn
After a prolonged period of flying straight and level
When flying through turbulence
When transitioning from instrument flight to visual flight
#12
What is the 'teapot effect' illusion?
An illusion where the aircraft's pitch attitude appears higher than it actually is during a descent.
A visual illusion caused by the curvature of the Earth, making distant objects appear higher than they are.
An optical illusion occurring when viewing objects with sharp angles or edges against a featureless background.
A phenomenon where the aircraft's shadow appears to elongate during certain times of the day.
#13
Which type of visual illusion is associated with the misinterpretation of ground lights or celestial lights, causing disorientation?
Flicker vertigo
Reversible perspective illusion
Pilot's cue illusion
Autokinesis
#14
Which visual illusion can occur when a pilot fixates on a single point during a prolonged turn?
Flicker vertigo
Autokinetic illusion
Coriolis illusion
Somatogravic illusion
