Q

This refers to when you’re in 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 which creates a sensation of turning, rotating and accelerating along an entirely different plane.

Q

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

A

4
Q

This occurs when an abrupt recovery or a rapid correction is made to a bank, sensing a roll in the opposite direction. This will cause you to correct and re-enter the original altitude. Maintaining level altitude for a minute or two will stop this.

A

5
Q

This states that a rapid acceleration can produce the illusion that you are in a nose-high altitude even though you are still in straight and level flight. Tendency is that you will lower the nose and then possibly enter a dive.

Q

This states that an abrupt change from climb to straight and level flight can create a feeling that you are tumbling backward. The effect may cause you to lower the nose abruptly which may intensify the illusion

Q

This 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

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 lifted left and upsloping

24
Q

Awareness of other aircraft, communications between air traffic control and other aircraft, weather and terrain

A

Environmental Awareness

25
Q

Awareness of aircraft configuration and flight control system modes

A

Mode Awareness

26
Q

A

Spatial Orientation

27
Q

28
Q

A

Time Horizon

29
Q

When does situational awareness tend to degrade?

A
  • Cockpit workload is extremely HIGH and/or extremely LOW (Complacency)
30
Q

What is the “CLEAROFF” check?

A

C - Compass and Heading Indicator, Check if synchronized
l - Log, accomplished
E - Engine & Electrics, on “green” normal
A - Altitude, check
R - Radio, set frequencies, working
O - Orientation of map, properly set
F - Fuel, check for quantity
F - Field, in case of emergency landing, selected

31
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)

32
Q

This provides a structured, systematic approach to analyzing changes that occur during a flight and how these changed might affect the safe outcome of a flight

A

Aeronautical Decision Making (ADM)

33
Q

State the steps for good decision-making

A
  • Identifying personal attitudes hazardous to safe flight
  • Learning behavior modification techniques
  • Learning how to recognize and cope with stress
  • Developing risk assessment skills
  • Using all resources
  • Evaluating the effectiveness of one’s ADM skills
34
Q

What are the two defining elements of ADM?

A

Hazard and Risk

35
Q

This is a real or perceived condition, event, or circumstance that a pilot encounters. The pilot assigns a value to the potential impact of this which qualifies the pilot’s assessment

A

Hazard

36
Q

This is an assessment of. the single or cumulative hazard facing a pilot

A

Risk

37
Q

They contribute to poor pilot judgement but can be effectively counteracted by redirecting the hazardous attitude so that correct action can be taken

A

Hazardous Attitudes

38
Q

What is the PAVE checklist?

A
  • Pilot-in-Command (PIC)
  • Aircraft
  • enVironment
  • External Pressures, influences external to the flight that can create a sense of pressure to complete a flight
39
Q

This determines physical and mental readiness for flying

A

IMSAFE checklist

40
Q

State the IMSAFE checklist

A
  1. Illness - Am i sick?
  2. Medication - AM i taking any medicines that might affect my judgement or make me drowsy?
  3. Stress - Am i under psychological pressure from the job? Do i have money, health, or family problems?
  4. Alcohol - Have i been drinking within 8 hours? 24 hours?
  5. Fatigue - Am i tired and not adequately rested?
  6. Emotion/Eating - Am i emotionally upset? Have i eaten yet?
41
Q

What is the DECIDE model?

A

D - Detect the fact that a change has occurred
E - Estimate the need to counter or react the change
C - Choose a desirable outcome for the success of the file
I - Identify actions which could successfully control the change
D - Do the necessary action to adapt the change
E - Evaluate the effect of the action

42
Q

What is the ACTION model?

A

A - Anticipate and assess the possible scenarios
C - Consider actions and outcomes
T - Time if available, immediate decision or nominate decision point
I - Implement Decision, make a control input, transmission etc
O - Observe the result and correct if necessary
N - Nominate the next milestone, decision point or potential hazard

43
Q

These are traps that pilots fall into, avoidance of which is actually simple in nature

A

Operational Pitfalls

44
Q

Poor decision-making may be based upon an emotional response to peers, rather than evaluating a situation objectively

A

Peer Pressure

45
Q

A pilot displays this through an inability to recognize and cope with changes in a given situation

A

Mindset

46
Q

This disposition impairs pilot judgment through a fixation on the original goal or destination, combine with a disregard for any alternative course of action

A

Get-there-itis

47
Q

A pilot may be tempted to make it into an airport by descending below minimums during an approach

A

Duck-under Syndrome

48
Q

This occurs when a pilot tries to maintain visual contact with the terrain at low altitude while instrument conditions exist

A

Scud Running

49
Q

Spatial Disorientation or collision with ground/obstacles may occur when a pilot continues VFR into instrument conditions

A

Continuing VFR into IMC

50
Q

This pitfall can be caused by allowing events or the situation to control pilot actions. A constant state of surprise at what happens next may be exhibited when the pilot is getting behind the aircraft

A

Getting behind the aircraft

51
Q

In extreme cases, when a pilot gets behind the aircraft, a loss of positional or situational awareness may result. The pilot may not know the aircraft’s geographical location or may be unable to recognize deteriorating circumstances

A

Loss of positional or situational awareness

52
Q

Ignoring minimum fuel reserve requirements is generally the result of overconfidence, lack of flight planning, or disregarding applicable regulations

A

Operating without adequate fuel reserves

53
Q

The duck-under syndrome, can also occur during the en route portion of an IFR flight

A

Descent below the minimum en route altitude

54
Q

The assumed high performance capability of a particular aircraft may cause a mistaken belief that it can , meet the demands imposed by a pilot’s overestimated flying skills

A

Flying outside the envelope

55
Q

A pilot may rely on short and long-term memory, regular flying skills, and familiar routes instead of established procedures and published checklists

A

Neglect of flight planning, preflight inspections, and checklists
