5P model
26
Explain the use of the 5P model to assess risk associated with each of the five factors
Plan - flight plan Plane - all system status Pilot - IMSAFE checklist Passengers - who are they Programming - What is it doing? Why is it doing? Did I do it?
27
When is the use of the 5P checklist recommended?
Regular intervals in all phases of flight action
28
Define the term aeronautical decision-making (ADM)
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
The DECIDE model of decision-making involves which elements?
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
How is the 3P model different from the DECIDE model of ADM?
3P is a continuous loop handling hazard whereas the DECIDE model focuses on a specific problem requiring resolution
31
How will you use the 3P model to recognize and mitigate risks throughout a flight?
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
Name five hazardous attitudes that can affect a pilot's ability to make sound decisions and properly exercise authority
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
Define the term risk management
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
What is the definition of a hazard?
Present condition, event, object, or circumstance that could lead to or contribute to an unplanned or undesired event
35
What are several examples of aviation hazards?
Crack prop Improper refueling Pilot fatigue Weather
36
What is the definition of risk?
The future impact of a hazard that is not controlled or eliminated
37
How can the use of the PAVE checklist during flight planning help you to assess risk?
Quick and simple way to examine all areas of risk Pilot Aircraft eVironment External Factors
38
Explain the use of a personal minimums checklist and how it can help a pilot control risk
What is legal doesn't constitute what is smart
39
What is one method you can use to identify risk before departure?
Set personal minimums for PAVE model
40
Explain the use of a personal checklist such as IMSAFE to determine personal risks
Self-assessment of physical and emotional states that could affect performance
41
Describe how the 3P model can be used for practical risk management
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
Explain how often a pilot should use the 3P model of ADM throughout the flight
Once a course of action has been selected the process starts again with the circumstances brought about due to the actions chosen
43
What is a risk assessment matrix?
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
What is a Flight Risk Assessment Tool (FRAT)?
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
Define the term task management
Process by which pilots manage the many, concurrent tasks that must be performed safely and efficiently operate an aircraft
46
What are several factors that can reduce a pilot's ability to manage workload effectively?
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
What are several options that a pilot can employ to decrease workload and avoid becoming overloaded?
Stop, think, slow down, and prioritize. Delegate certain tasks if/when possible. Use of autopilot or ATC
48
What is one method of prioritizing tasks to avoid an overload situation?
Aviate, navigate, communicate
49
How can tasks be completed in a timely manner without causing a distraction from flying?
Planning, prioritizing, and sequencing tasks
50
What are two common methods of checklist usage?
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
What are several examples of common errors that can occur while using the checklist?
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
What are several recommended methods of managing checklist accomplishment?
Physical interaction Verbally state checklist item action Announce when checklist is complete
52
What are immediate action items?
Items that must be accomplished before referring to the checklist
53
Discuss the importance of understanding the procedure for the positive exchange of flight controls
Clear assumptions in the flight deck. Verbal announcement of relinquishing control, followed by the acceptance transfer, reconfirms the relinquishing control
54
Define the term situational awareness
The accurate perception and understanding of all factors and conditions within the four fundamental risk areas (PAVE)
55
What are some of the elements inside and outside the aircraft that a pilot must consider to maintain situational awareness?
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
What are several factors that reduce situational awareness?
Factors that reduce SA include distractions, unusual or unexpected events, complacency, high workload, unfamiliar situations, and inopt equipment
57
When flying a technically advanced aircraft (TAA), what are several procedures that help ensure that situational awareness is enhanced, not diminished, by the automation?
Double check the system and use of verbal callouts
58
What additional procedures can be used for maintaining situational awareness in technically advanced aircraft?
Verification checks of all programming Check flight routing Verify all waypoints Backup all types of navigation equipment Match use with pilot proficiency Plan a realistic flight route Verify all keystrokes
59
A majority of controlled flight into terrain (CFIT) accidents have been attributed to what factors?
Lack of pilot currency Loss of SA Pilot distraction and breakdown of SRM Failure to comply with minimums Breakdown of effective ADM Insufficient planning, especially descent and arrival
60
A pilot can decrease the likelihood of a CFIT accident at the destination by identifying what risk factors prior to flight?
Airport location, runway lighting, weather/daylight conditions, approach specs, ATC capabilities, pilot phraseology, and crew configuration
61
Describe several operational techniques that will help you avoid a CFIT accident?
Maintain SA Adhere to takeoff and departure procedures Become familiar with surrounding terrain features and obstacles Adhere to published routes and minimums Fly a stabilized approach Understand ATC clearances and instructions Don't be complacent
62
What is the sterile cockpit rule and how can adherence to this rule prevent CFIT accidents?
Crewmembers refrain from nonessential activities during critical phases of flight which reduce distractions during critical phases of flight
63
What does the term automation management refer to?
Ability to control and navigate an aircraft by means of automated systems installed in the aircraft
64
In what three areas must a pilot be proficient when using advanced avionics or any automated system?
