Q

As a flight crewmember, you discover you have high blood pressure. You have a current medical certificate. Can you continue to exercise the privileges of your certificate?

A

No; Regulations prohibit a pilot from performing crewmember duties while the pilot has a known medical condition or increase of known medical condition that would make the pilot unable to meet the medical standards

Q

What factors can make a pilot more susceptible to hypoxia?

A

CO fumes from smoking or exhaust fumes
Anemia (lower hemoglobin)
Certain medication
Small amount of alcohol

Q

For a pilot who has been taking an over-the-counter cold medication, how do the various environmental factors the pilot is exposed to in-flight affect the drug’s physiological impairment on the pilot?

A

Drugs that cause no apparent side effects on the ground may change due to the changes in the oxygen in the blood stream relative to altitude, even with the smallest changes in altitude.

Q

Define the term aeronautical decision-making (ADM)

A

A systematic mental approach to consistently determine the best course of action in response to a given set of circumstances. Two most common models are the DECIDE and 3P models

29
Q

The DECIDE model of decision-making involves which elements?

A

Detect a change needing attention
Estimate the need to counter or react to a change
Choose the most desirable outcome
Identify actions to successfully control the change
Do something to adapt the change
Evaluate the effect of the action countering the change

30
Q

How is the 3P model different from the DECIDE model of ADM?

A

3P is a continuous loop handling hazard whereas the DECIDE model focuses on a specific problem requiring resolution

31
Q

How will you use the 3P model to recognize and mitigate risks throughout a flight?

A

Once a course of action has been selected the process begins again with changes brought about with the course of action - it is therefore a continuous loop

32
Q

Name five hazardous attitudes that can affect a pilot’s ability to make sound decisions and properly exercise authority

A

Anti-authority - Follow the rules
Impulsivity - Think first
Invulnerability - It could happen to me
Macho - Taking chances is foolish
Resignation - I can make a difference

33
Q

Define the term risk management

A

Decision-making process designed to systematically identify hazards, assess the degree of risk, and weigh the potential costs of risks against the possible benefits of allowing those risks to stand uncontrolled

34
Q

A

Present condition, event, object, or circumstance that could lead to or contribute to an unplanned or undesired event

35
Q

What are several examples of aviation hazards?

39
Q

What is one method you can use to identify risk before departure?

A

Set personal minimums for PAVE model

40
Q

Explain the use of a personal checklist such as IMSAFE to determine personal risks

A

Self-assessment of physical and emotional states that could affect performance

41
Q

Describe how the 3P model can be used for practical risk management

A

Perceive - hazards for flight (PAVE)
Process - evaluate the impact of the hazards (C; consequence, A; alternatives available, R; reality of the situation, E; external pressures that might influence analysis)
Perform - implement the best course of actions (T; transfers, E; eliminate, A; accept, M; mitigate)

42
Q

Explain how often a pilot should use the 3P model of ADM throughout the flight

A

Once a course of action has been selected the process starts again with the circumstances brought about due to the actions chosen

43
Q

What is a risk assessment matrix?

A

A tool used to assess the likelihood of an event occurring and the severity or consequences of that event. The matrix differentiates between levels of risk factor

44
Q

What is a Flight Risk Assessment Tool (FRAT)?

A

Preflight planning tool that uses a series of questions in each major risk category (PAVE) to help identify and quantify risk for a flight

45
Q

Define the term task management

A

Process by which pilots manage the many, concurrent tasks that must be performed safely and efficiently operate an aircraft

46
Q

What are several factors that can reduce a pilot’s ability to manage workload effectively?

A

Environmental Conditions - Conditions beyond normal operating conditions
Physiological stress - Conditions causing a lack of focus
Psychological stress - Conditions causing a lack of mental capacity

47
Q

What are several options that a pilot can employ to decrease workload and avoid becoming overloaded?

A

Stop, think, slow down, and prioritize. Delegate certain tasks if/when possible. Use of autopilot or ATC

48
Q

What is one method of prioritizing tasks to avoid an overload situation?

A

Aviate, navigate, communicate

49
Q

How can tasks be completed in a timely manner without causing a distraction from flying?

A

Planning, prioritizing, and sequencing tasks

50
Q

What are two common methods of checklist usage?

A

Do-Verify (DV) method - Use the checklist to verify the actions have been accomplished

Challenge-Do-Verify (CDV) method - One pilot issues a challenge then action is performed then a checklist is used to verify that action has been accomplished (two crew environment)

51
Q

What are several examples of common errors that can occur while using the checklist?

A

Missed items due to distraction
Items incorrectly performed
Failure to use the appropriate checklist
Too much time head down reading checklist
Checklist not readily available
Emergency/abnormal checklist not readily available
Memory items are accomplished but not verified with checklist

51
Q

What are several recommended methods of managing checklist accomplishment?

A

Physical interaction
Verbally state checklist item action
Announce when checklist is complete

52
Q

What are immediate action items?

A

Items that must be accomplished before referring to the checklist

53
Q

Discuss the importance of understanding the procedure for the positive exchange of flight controls

A

Clear assumptions in the flight deck. Verbal announcement of relinquishing control, followed by the acceptance transfer, reconfirms the relinquishing control

54
Q

Define the term situational awareness

A

The accurate perception and understanding of all factors and conditions within the four fundamental risk areas (PAVE)

55
Q

What are some of the elements inside and outside the aircraft that a pilot must consider to maintain situational awareness?

A

Inside the aircraft - status of systems, pilot, and passengers

Outside of the aircraft - awareness of where the aircraft is in relation to terrain, traffic, weather, and airspace

56
Q

What are several factors that reduce situational awareness?

A

Factors that reduce SA include distractions, unusual or unexpected events, complacency, high workload, unfamiliar situations, and inopt equipment

57
Q

When flying a technically advanced aircraft (TAA), what are several procedures that help ensure that situational awareness is enhanced, not diminished, by the automation?

A

Double check the system and use of verbal callouts
