30
Q

What is the recommended waiting time before going to fly up to 8000 ft after SCUBA diving?

A

At least 12 hrs after after non decompression stop diving, and 24 hours after decompression stop diving

31
Q

What is the recommended waiting time before going to fly ABOVE 8000 ft after SCUBA diving?

A

At least 24 hrs

32
Q

What can result from hyperventilation?

A

Spiraling issues eventually resulting in unconsciousness

33
Q

What should happen if a pilot starts to experience hyperventilation while using a supplemental oxygen system?

A

It should be set to 100% oxygen and then the system checked to make sure it is working properly before paying attention to rate and depth of breathing

34
Q

What is the typical cause of aircraft accidents resulting from carbon monoxide poisoning?

A

Exhaust fumes escaping from cracks and seals in the manifold into cabin heaters

35
Q

What should a pilot due if they smell exhaust fumes or feel headache, drowziness, or dizziness while using the heater?

A

Turn off the heater and open all air vents

36
Q

What is The Leans illusion?

A

When a plane slowly enters a banked attitude and then is rapidly corrected, an illusion that the plane is in a banked attitude when level can occur and “correction” back to the banked attitude can happen.

37
Q

What is the Coriolis Illusion?

A

An abrupt head movement in a prolonged constant-bank turn can result in an illusion of rotation or movement in an entirely different access

38
Q

What is Somatogravic illusion?

A

A feeling of the plane pitching up or down due to acceleration or deceleration, resulting in a wrong “correction”

39
Q

What is inversion illusion?

A

An abrupt change from a climb to straight and level flight can produce the sensation of tumbling backwards, resulting in a “correction” to a nose low/dive, further exacerbating the illusion

40
Q

What is the elevator illusion?

A

An abrupt upward vertical upward or downward acceleration (often caused by updrafts or downdrafts) can create the illusion of being in a climb or descent

41
Q

What is the False Horizon illusion?

A

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

42
Q

What is Autokinesis?

A

In the dark, a static light will appear to move about when stared at for a little while.

43
Q

What is Runway Width illusion?

A

A narrower or wider than usual runway can create the illusion that the aircraft is at a higher or lower altitude than it actually is (lower for narrower, higher for wider)

44
Q

What is Runway and Terrain Slopes illusion?

A

An upsloping or downsloping runway causing the pilot to think they are higher or lower than they actually are

45
Q

What is the Featureless Terrain illusion?

A

Landing over a featureless area can create the illusion that the aircraft is at a higher altitude than it actually is, resulting in a lower approach

46
Q

What are atmospheric illusions?

A

Rain on the windscreen, atmospheric haze, and fog can create issues of greater height, greater distance from the runway, or pitching up

47
Q

What is the ground lighting illusion?

A

Lights along a straight path can be mistaken for a runway, and runway lights in areas where the lights illuminate the terrain can create the illusion of less distance to the runway

48
Q

What are the light-sensitive cells in the eye called?

A

Rods and cones

49
Q

Where does most “looking” occur in the eye?

A

The fovea; a small pit at the back of the eye where detail, color sensitivity and resolution are highest

50
Q

What type of eye cells are better able to detect movement and provide vision in dim light?

A

Rods

51
Q

Of the body senses, which is most important for safe flight?

A

Vision

52
Q

What is dark adaptation?

A

A process by which vision becomes more sensitive to light

53
Q

When should you use red cockpit lighting?

A

Only when optimum outside night vision capabilities are necessary because colors, especially on aeronautical charts, are severely distorted by red light.

54
Q

What percentage of light and what color should your sunglasses absorb?

A

15% transmittance and all colors equally (neutral transmittance)

55
Q

Approximately how much time should your focus be inside the cabin vs. outside the plane?

A

1/4 to 1/3 inside, remainder outside

56
Q

What is Empty Field Myopia?

A

A condition that occurs when flying above the clouds or in a haze layer that provides nothing specific to focus on outside the aircraft, resulting in the eyes relaxing and seeking a comfortable focal distance that prevents the pilot from actually seeing things outside the airfract

57
Q

What are some examples of situations where the NTSB should be contacted?

A

An aircraft accident, flight control systems malfunction or failure, inability of any crew member to perform flight duties due to injury or illness, failure of structural components of a turbine, in-flight fire, in-flight aircraft collision, damage to property other than the aircraft estimated to exceed $25,000 for repair or total loss

58
Q

How soon after an incident does a pilot need to file a report with the NTSB?

A

Within 10 days after an accident or after 7 days if an overdue aircraft is still missing

59
Q

How should an accident site be handled by the pilot?

A

The site should be left alone and preserved until NTSB takes custody of the situation, except to remove injured or trapped persons, protect the wreckage from further damage, or protect the public from injury

60
Q

What is ADM?

A

Aeronatical Decision-Making

61
Q

What do decision aids help with?

A

Preventing the most human of frailties; forgetting

62
Q

What does the effectiveness of ADM rely on?

A

The knowledge required to understand the situation, the information available, the possible options, the skills required to execute a decision, and the self-awareness to recognize when hazardous attitudes are influencing decisions and the self-discipline to overcome those attitudes

63
Q

What does risk management, as an ADM process, rely on?

A

Analysis of all information in a particular situation and making of a timely decision on what action to take

64
Q

In broad terms, what is a hazard?

A

A hazard is a condition that, if left unchecked, becomes a risk

65
Q

What is a risk?

A

A risk is the future impact of a hazard that is not controlled or eliminated

66
Q

What is the AIM?

A

Aeronautical Information Manual; the bible!

67
Q

What are the main parts of 14 CFR that concern pilots?

A

61 and 91

68
Q

If the airplane needs to be flown to somewhere where its 100 hr inspection needs to be done, but that will put it past 100 hours, is that allowed?

A

Yes, but it must stay within 10 hours and any time past 100 needs to be subracted from the next 100 hours to inspection

69
Q

How often does a pilot need to do a pilot review?

A

Once every 24 months unless the pilot has had a proficiency check within 24 months
