AIM 8-1-4(a)

27
Q

What are the leans?

A

An abrupt correction of a banked attitude, which has been entered too slowly to stimulate the motion sensing system in the inner ear, can create the illusion of banking in the opposite direction. The disoriented pilot will roll the aircraft back into its original dangerous attitude, or if level flight is maintained, will feel compelled to lean in the perceived vertical plane

AIM 8-1-5(b)(2)

28
Q

What is the coriolis illusion?

A

An abrupt head movement in a prolonged constant-rate turn that has ceased stimulating the motion sensing system can create the illusion of rotation or movement in an entirely different axis. the disoriented pilot will maneuver the aircraft into a dangerous attitude in an attempt to stop rotation

AIM 8-1-5(b)(2)(a)

29
Q

What is a graveyard spin?

A

A proper recovery from a spin that has ceased stimulating the motion sensing system can create the illusion of spinning in the opposite direction. The disoriented pilot will return the aircraft to its original spin

AIM 8-1-5(b)(2)(b)

30
Q

What is a graveyard spiral?

A

An observed loss of altitude during a coordinated constant-rate turn that has ceased stimulating the motion sensing system can create the illusion of being in a descent with wings level. The disoriented pilot will pull back on the controls, tightening the spiral and increasing the loss of altitude

AIM 8-1-5(b)(2)(c)

31
Q

What is the somatogravic illusion?

A

A rapid acceleration during takeoff can create the illusion of being in a nose up attitude. A rapid deceleration can have the opposite effect

AIM 8-1-5(b)(2)(d)

32
Q

What is the inversion illusion?

A

An abrupt change from climb to straight and level flight can create the illusion of tumbling backwards

AIM 8-1-5(b)(2)(e)

33
Q

What is the elevator illusion?

A

An abrupt upward vertical acceleration, usually by an updraft, can create the illusion of being in a climb. An abrupt downward vertical acceleration, usually by a downdraft, has the opposite effect

AIM 8-1-5(b)(2)(f)

34
Q

What is a false horizon?

A

Sloping cloud formations, an obscured horizon, a dark scene spread with ground lights and stars, and certain geometric patterns of ground light can create illusions of not being aligned correctly with the actual horizon

AIM 8-1-5(b)(2)(g)

35
Q

What is autokinesis?

A

In the dark, a static light will appear to move about when stared at for many seconds

AIM 8-1-5(b)(2)(h)

36
Q

What approach will a pilot fly when approaching a narrower-than-usual runway?

A

The aircraft will appear higher than it actually is leading the pilot to fly a lower than normal approach

AIM 8-1-5(b)(3)(b)

37
Q

What approach will a pilot fly when approaching a wider-than-usual runway?

A

The aircraft will appear lower than it actually is leading the pilot to fly a higher than normal approach

AIM 8-1-5(b)(3)(b)

38
Q

How does an upsloping runway or terrain affect a pilots approach?

A

The aircraft will appear higher than it actually is leading the pilot to fly a lower than normal approach

AIM 8-1-5(b)(3)(c)

39
Q

How does a downsloping runway or terrain affect a pilots approach?

A

The aircraft will appear lower than it actually is leading the pilot to fly a higher than normal approach

AIM 8-1-5(b)(3)(c)

40
Q

How does a featureless terrain affect a pilots approach to landing?

A

The aircraft will appear higher than it actually is leading the pilot to fly a lower than normal approach

AIM 8-1-5(b)(3)(c)

41
Q

How does rain on the windscreen affect a pilots approach to landing?

A

It will create the illusion of greater height leading to a lower approach

AIM 8-1-5(b)(3)(e)

42
Q

How does atmospheric haze affect a pilots approach to landing?

A

It will create the illusion of greater height leading to a lower approach

AIM 8-1-5(b)(3)(e)

43
Q

How does fog affect a pilots approach to landing?

A

It will create the illusion of pitching up causing the pilot to steepen the approach

AIM 8-1-5(b)(3)(e)

44
Q

How does ground lighting affect a pilots approach to landing?

A
  • Lights along a straight path can be mistaken for a runway and approach lights.
  • Bright runway and approach lights may create the illusion of less distance to the runway leading to a higher approach
  • Terrain which has few lights to provide height cues may lead to a lower than normal approach

AIM 8-1-5(b)(3)(f)

45
Q

How long does it take the eyes to fully adjust to the dark?

A

30 minutes

AIM 8-1-6(b)(2)

A

20 minutes

AIM 8-1-6(b)(2)

47
Q

Q

How many degrees can the eye observe across the horizon?

A

200 degrees

AIM 8-1-6(c)(2)

49
Q

What is the small center area of vision that sends clear, sharply focused messages to the brain called?

A

Fovea

AIM 8-1-6(c)(3)

50
Q

How should a pilot scan for traffic in the sky?

A

Short, regularly spaced eye movements not to exceed 10 degrees

AIM 8-1-6(c)(2)

51
Q

How can a pilot reduce eye fatigue when scanning for traffic?

A

Start from the instruments, out to the left wing past the wing tip, to the right, and back into the cabin along the right wing

AIM 8-1-6(c)(4)

52
Q

How far can the eye see during “empty-field myopia”?

A

10 to 30 feet

AIM 8-1-6(c)(5)

53
Q

What might a pilot expierence with a rapid push-over maneuver?

A

Blood and body organs will be displaced toward the head leading to discomfort, headache, “red-out,” and even unconsciouness

AIM 8-1-7(b)

54
Q

What might a pilot experience will a rapid pull-up maneuver or steep-turn?

A

Blood circulation to the brain decreases and the pilot will experience “narrowing” or the visual fields, “grey-out,” “black-out,” and unconsciousness
