About these flashcards

These flashcards cover the basics of human vision and its relevance to piloting, aimed at primary school students. They explore key concepts like light, vision, and the eye, focusing on how pilots perceive runways, objects, and illusions during flight. The flashcard set delves into the structure and function of the eye, including the retina, lens, and adaptation to light and dark. It also covers common visual illusions pilots may encounter, such as the autokinetic phenomenon and the black hole effect. Aspiring pilots and aviation enthusiasts will find this flashcard set particularly useful for understanding the visual challenges and adaptations required in aviation.

The onset of presbyopia depends

on the degeneration of the vitreous humor

only on age

on age and weather the subjects is shortsighted, farsighted, or normal sighted

on the degeneration of the retina

The following statements are true except

cones are responsible for night vision and are most densely in the fovea centralis

rods are responsible for night vision and have a poor ability to discriminate

cones are most densely in the fovea centralis and have a one-to-one connection to the brain

rods are responsible for ambient vision and are in groups connected to the brain

Color vision is performed by three different classes of cones:

yellow, blue, red

green, blue, yellow

red, yellow, blue

red, green, blue

The normal visual acuity allows discrimination of two different points under an angle of

1 degree of arc

1 minute of arc

10 minutes of arc

1 second of arc

Which one of the following statements is correct regarding the use of cockpit lighting for night flight?

Reducing the light intensity to a minimum level will eliminate blind spots

Coloration shown on maps is least affected by the use of direct red lighting

Cockpit lighting may only be used during short intervals to protect the light adaption

The use of regular white light, such as flashlight, will impair night adaption

If the pilot of an aircraft approaches a runway that is wider than normal, one of the possible consequences could be that:

He would choose a visual touch down point too far into the runway

He would flare at a too low altitude

The aircraft would touch down after he expects to

He would touch down with excess speed

Below are four statements about rods and cones. Which one is true?

Cones give the best visual acuity

Rods are sensitive to color and small details

Rods are concentrated around the fovea

Cones are effective in both daylight and darkness

Visual acuity is best within ….. degrees of the fovea and reduces ….. towards the periphery of vision:

20, rapidly

2-3, rapidly

20, gradually

2-3, gradually

The part of the eye that bends the light the most is:

fluid in the eye

the iris

the lens

the cornea

If runway slopes downwards, what is a pilot is likely to do:

make an approach with too low speed

land short

make a shallow approach

land long

A sloping cloud formation, an obscured horizon and a dark scene spread with ground lights and stars can create an illusion

known as:

False horizon

Coriolis illusion

Autokinesis

Elevator illusion

Suppose you make an approach to a runway which is narrower than standard. Which of the following errors are you likely to commit?

Initiate a flare too early

Initiate a flare too late

Not following the VASIS

Fly with a too high approach speed, as a narrow runway requires lower speed
