FOVEA

20
Q

Rods are not always instantly ready for use. The rods contain a substance called

A

rhodopsin, or visual purple.

21
Q

○ This is the loss of proper bearings; state of mental confusion as to position,
location, or movement relative to the position of the earth.
○ An incorrect mental image of your position, attitude or movement in relation to what is actually happening to your aircraft.
○ Can be caused by misleading information being sent to the brain by your body’s various sensory organs.

A

SPATIAL DISORIENTATION

22
Q

It acts as the receptor organ for visual sensations

A

THE EYE

23
Q

It acts as the receptor organ for visual sensations

A

THE EYE

24
Q

The tension of the various muscles in your body assist you in determining your
position within a frame of reference, as well as any motion with respect to this
reference.
○ This is also known as “flying by the seat of your pants”.

A

SKELETAL MUSCLES

25
Q

○ One end of each semicircular canal in the
ear is enlarged, and in this area is a mound
of sensory hair cells.
○ Angular acceleration, or rotation, of the
body along either the yaw, pitch, or roll axis
will move the fluid in a respective canal.
○ This movement displaces the sensory hairs
and an impulse is sent to the brain to be
interpreted as motion about a known axis.

A

VESTIBULAR APPARATUS

26
Q

During a constant rate turn, if you tilt your
head down to get a pen, the rapid head
movement puts the fluid in motion in more
than one semicircular canal.

A

CORIOLIS ILLUSION

27
Q

● Once the turn to the right is detected, and
the turn is stopped, the fluid in the canal will
continue to move.
● This would cause an opposite sensation as
though one was now turning to the left.

A

GRAVEYARD SPIN AND SPIRAL

28
Q

Occurs when an abrupt recovery or a
rapid correction is made to a bank,
sensing a roll in the opposite direction.

A

LEANS ILLUSION

29
Q

During a constant rate turn, if you tilt your
head down to get a pen, the rapid head
movement puts the fluid in motion in more
than one semicircular canal.

“rapid correction”

A

LEANS ILLUSION

32
Q

A rapid acceleration can produce the
illusion that you are in a nose-high
attitude even though you are still in
straight and level flight

“rapid acceleration”

A

SOMATOGRAVIC ILLUSION

33
Q

4 types of Visual illusions

A

○ Autokinesis
○ False Horizons
○ Vection Illusion
○ Black-Hole Approach Illusion

34
Q

An abrupt change from climb to straight
and level flight can create a feeling that
you are tumbling backward.

A

INVERSION ILLUSION

35
Q

At night, a static light may appear to move if it is allowed to become the prime focus fof attention

A

AUTOKINESIS

36
Q

these illusions are caused by flying over a banked cloud, night flying over a
featureless terrain with ground lights that are indistinguishable from a dark sky with
stars, or night flying over a featureless terrain with a clearly defined pattern of
ground lights and a dark, starless sky.

A

FALSE HORIZONS

37
Q

________ __________ is a common example is when you are stopped at a traffic light in your
car and the car next to you edges forward. Your brain interprets this peripheral
visual information as though you are moving backwards and makes you apply
additional pressure to the brakes.

A

VECTION ILLUSION

38
Q

This can happen during a final approach at night (no stars or moonlight) over water
or un-lighted terrain to a lighted runway beyond which the horizon is not visible.
● When peripheral visual cues are not available to help you orient yourself relative to
the earth, you may have the illusion of being upright and may perceive the runway
to be tilted left and upsloping

A

BLACK-HOLE ILLUSION

39
Q

○ A final approach over a flat terrain with an upsloping runway may produce the visual
illusion of a high-altitude final approach.
○ If you believe this illusion, you may respond by pitching the aircraft nose down to
decrease the altitude, which, if performed too close to the ground, may result in an
accident.

A

Upsloping Runway

40
Q

○ A final approach over a flat terrain with a downsloping runway may produce the visual
illusion of a low-altitude final approach.
○ If you believe this illusion, you may respond by pitching the aircraft nose up to
increase the altitude, which may result in a low-altitude stall or a missed approach.

A

Downsloping Runway

41
Q

It is a systematic approach to the mental process used by airplane pilots to consistently
determine the best course of action in response to a given set of circumstances.

A

AERONAUTICAL DECISION
MAKING (ADM)

42
Q

are traps that pilots
fall into, avoidance of which is actually
simple in nature.
● These are classic behavioral traps into
which pilots have been known to fall.
