4. Integrate risk management into planning at all levels. Because risk is an unavoidable part of

every flight, safety requires the use of appropriate and effective risk management not just in

the preflight planning stage, but in all stages of the flight.

While poor decision-making in everyday life does not always lead to tragedy, the margin for error in

aviation is thin. Since ADM enhances management of an aeronautical environment, all pilots should

become familiar with and employ ADM.

Crew Resource Management (CRM) and Single-Pilot Resource Management

While CRM focuses on pilots operating in crew environments, many of the concepts apply to single-

pilot operations. Many CRM principles have been successfully applied to single-pilot aircraft and led to

the development of Single-Pilot Resource Management (SRM). SRM is defined as the art and science of

managing all the resources available to a single pilot (prior to and during flight) to ensure the

successful outcome of the flight. SRM includes the concepts of ADM, risk management (RM), task

management (TM), automation management (AM), controlled flight into terrain (CFIT) awareness, and

situational awareness (SA). SRM training helps the pilot maintain situational awareness by managing

the automation and associated aircraft control and navigation tasks. This enables the pilot to

accurately assess and manage risk and make accurate and timely decisions.

SRM is all about helping pilots learn how to gather information, analyze it, and make decisions.

Hazard and Risk

Two defining elements of ADM are hazard and risk. Hazard is a real or perceived condition, event, or

circumstance that a pilot encounters. When faced with a hazard, the pilot makes an assessment of that

hazard based upon various factors. The pilot assigns a value to the potential impact of the hazard,

which qualifies the pilot’s assessment of the hazard—risk.

Therefore, risk is an assessment of the single or cumulative hazard facing a pilot; however, different

pilots see hazards differently.

Hazardous Attitudes and Antidotes

Being fit to fly depends on more than just a pilot’s physical condition and recent experience. For

example, attitude affects the quality of decisions. Attitude is a motivational predisposition to

respond to people, situations, or events in a given manner. Studies have identified five hazardous

attitudes that can interfere with the ability to make sound decisions and exercise authority properly:

anti-authority, impulsivity, invulnerability, macho, and resignation. [Figure 10-2]

Hazardous attitudes contribute to poor pilot judgment but can be effectively counteracted by

redirecting the hazardous attitude so that correct action can be taken. Recognition of hazardous

thoughts is the first step toward neutralizing them. After recognizing a thought as hazardous, the

pilot should label it as hazardous, then state the corresponding antidote. Antidotes should be

memorized for each of the hazardous attitudes so they automatically come to mind when needed.

Risk

During each flight, the single pilot makes many decisions under hazardous conditions. To fly safely,

the pilot needs to assess the degree of risk and determine the best course of action to mitigate the

risk.

Assessing Risk

For the single pilot, assessing risk is not as simple as it sounds. For example, the pilot acts as his or

her own quality control in making decisions. If a fatigued pilot who has flown 16 hours is asked if

he or she is too tired to continue flying, the answer may be “no.” Most pilots are goal oriented

and when asked to accept a flight, there is a tendency to deny personal limitations while adding

weight to issues not germane to the mission. For example, pilots of helicopter emergency

services (EMS) have been known (more than other groups) to make flight decisions that add

significant weight to the patient’s welfare. These pilots add weight to intangible factors (the

patient in this case) and fail to appropriately quantify actual hazards, such as fatigue or weather,

when making flight decisions. The single pilot who has no other crew member for consultation

must wrestle with the intangible factors that draw one into a hazardous position. Therefore, he

or she has a greater vulnerability than a full crew.

Mitigating Risk

Risk assessment is only part of the equation.

One of the best ways single pilots can mitigate risk is to use the IMSAFE checklist to determine

physical and mental readiness for flying:

1. Illness—Am I sick? Illness is an obvious pilot risk.

2. Medication—Am I taking any medicines that might affect my judgment or make me drowsy?

3. Stress—Am I under psychological pressure from the job? Do I have money, health, or family

problems? Stress causes concentration and performance problems. While the regulations list

medical conditions that require grounding, stress is not among them. The pilot should

consider the effects of stress on performance.

4. Alcohol—Have I been drinking within 8 hours? Within 24 hours? As little as one ounce of

liquor, one bottle of beer, or four ounces of wine can impair flying skills. Alcohol also renders

a pilot more susceptible to disorientation and hypoxia.

5. Fatigue—Am I tired and not adequately rested? Fatigue continues to be one of the most

insidious hazards to flight safety, as it may not be apparent to a pilot until serious errors are

made.

6. Emotion—Am I emotionally upset?

The PAVE Checklist

Another way to mitigate risk is to perceive hazards. By incorporating the PAVE checklist into

preflight planning, the pilot divides the risks of flight into four categories: Pilot-in-command (PIC),

Aircraft, enVironment, and External pressures (PAVE) which form part of a pilot’s decision-making

process.

With the PAVE checklist, pilots have a simple way to remember each category to examine for risk

prior to each flight.

Once a pilot identifies the risks of a flight, he or she needs to decide whether the risk, or

combination of risks, can be managed safely and successfully. If not, make the decision to cancel the

flight. If the pilot decides to continue with the flight, he or she should develop strategies to mitigate

the risks. One way a pilot can control the risks is to set personal minimums for items in each risk

category. These are limits unique to that individual pilot’s current level of experience and

proficiency.

P = Pilot-in-Command (PIC)

The pilot is one of the risk factors in a flight. The pilot must ask, “Am I ready for this flight?” in

terms of experience, recency, currency, physical, and emotional condition. The IMSAFE checklist

provides the answers.

A = Aircraft

What limitations will the aircraft impose upon the trip? Ask the following questions:

• Is this the right aircraft for the flight?

• Am I familiar with and current in this aircraft?

• Can this aircraft carry the planned load?

Chapter 10: Aeronautical Decision-Making and Judgment

Remote Pilot – Small Unmanned Aircraft Systems Study Guide 56

V = EnVironment

Weather

Weather is a major environmental consideration. Earlier it was suggested pilots set their own

personal minimums, especially when it comes to weather. As pilots evaluate the weather for a

particular flight, they should consider the following:

• What is the current ceiling and visibility?

• Consider the possibility that the weather may be different than forecast.

• Are there any thunderstorms present or forecast?

• If there are clouds, is there any icing, current or forecast? What is the temperature/dew point

spread and the current temperature at altitude?

Terrain

Evaluation of terrain is another important component of analyzing the flight environment.

Airspace

Check the airspace and any temporary flight restriction (TFRs).

E = External Pressures

External pressures are influences external to the flight that create a sense of pressure to

complete a flight—often at the expense of safety. Factors that can be external pressures include

the following:

• The desire to demonstrate pilot qualifications

• The desire to impress someone (Probably the two most dangerous words in aviation are

“Watch this!”)

• The pilot’s general goal-completion orientation

• Emotional pressure associated with acknowledging that skill and experience levels may be

lower than a pilot would like them to be. Pride can be a powerful external factor!

Managing External Pressures

Management of external pressure is the single most important key to risk management because

it is the one risk factor category that can cause a pilot to ignore all the other risk factors.

The use of personal standard operating procedures (SOPs) is one way to manage external

pressures. The goal is to supply a release for the external pressures of a flight.

Human Factors

Why are human conditions, such as fatigue, complacency and stress, so important in aviation? These

conditions, along with many others, are called human factors. Human factors directly cause or

contribute to many aviation accidents and have been documented as a primary contributor to more

than 70 percent of aircraft accidents.

Typically, human factor incidents/accidents are associated with flight operations but recently have also

become a major concern in aviation maintenance and air traffic management as well. Over the past

several years, the FAA has made the study and research of human factors a top priority by working

closely with engineers, pilots, mechanics, and ATC to apply the latest knowledge about human factors

in an effort to help operators and maintainers improve safety and efficiency in their daily operations.

Human factors science, or human factors technologies, is a multidisciplinary field incorporating

contributions from psychology, engineering, industrial design, statistics, operations research, and

anthropometry. It is a term that covers the science of understanding the properties of human

capability, the application of this understanding to the design, development and deployment of

systems and services, and the art of ensuring successful application of human factor principles into all

aspects of aviation to include pilots, ATC, and aviation maintenance. Human factors is often considered

synonymous with CRM or maintenance resource management (MRM) but is really much broader in

both its knowledge base and scope. Human factors involves gathering research specific to certain

situations (i.e., flight, maintenance, stress levels, knowledge) about human abilities, limitations, and

other characteristics and applying it to tool design, machines, systems, tasks, jobs, and environments

to produce safe, comfortable, and effective human use. The entire aviation community benefits greatly

from human factors research and development as it helps better understand how humans can most

safely and efficiently perform their jobs and improve the tools and systems in which they interact.

The Decision-Making Process

An understanding of the decision-making process provides the pilot with a foundation for developing

ADM and SRM skills. While some situations, such as engine failure, require an immediate pilot

response using established procedures, there is usually time during a flight to analyze any changes that

occur, gather information, and assess risks before reaching a decision.

Risk management and risk intervention is much more than the simple definitions of the terms might

suggest. Risk management and risk intervention are decision-making processes designed to

systematically identify hazards, assess the degree of risk, and determine the best course of action.

These processes involve the identification of hazards, followed by assessments of the risks, analysis of

the controls, making control decisions, using the controls, and monitoring the results.

The steps leading to this decision constitute a decision-making process. Three models of a structured

framework for problem-solving and decision-making are the 5P, the 3P using PAVE, CARE and TEAM,

and the DECIDE models. They provide assistance in organizing the decision process. All these models

have been identified as helpful to the single pilot in organizing critical decisions.

Single-Pilot Resource Management (SRM)

Single-Pilot Resource Management (SRM) is about how to gather information, analyze it, and make

decisions. Learning how to identify problems, analyze the information, and make informed and

timely decisions is not as straightforward as the training involved in learning specific maneuvers.

Learning how to judge a situation and “how to think” in the endless variety of situations

encountered while flying out in the “real world” is more difficult.

There is no one right answer in ADM, rather each pilot is expected to analyze each situation in light

of experience level, personal minimums, and current physical and mental readiness level, and make

his or her own decision.

Perceive, Process, Perform (3P) Model

The Perceive, Process, Perform (3P) model for ADM offers a simple, practical, and systematic

approach that can be used during all phases of flight. To use it, the pilot will:

• Perceive the given set of circumstances for a flight

• Process by evaluating their impact on flight safety

• Perform by implementing the best course of action

Chapter 10: Aeronautical Decision-Making and Judgment

Remote Pilot – Small Unmanned Aircraft Systems Study Guide 58

Use the Perceive, Process, Perform, and Evaluate method as a continuous model for every

aeronautical decision that you make. Although human beings will inevitably make mistakes,

anything that you can do to recognize and minimize potential threats to your safety will make you a

better pilot.

Depending upon the nature of the activity and the time available, risk management processing can

take place in any of three timeframes. [Figure 10-3] Most flight training activities take place in the

“time-critical” timeframe for risk management. The six steps of risk management can be combined

into an easy-to-remember 3P model for practical risk management: Perceive, Process, Perform with

the PAVE, CARE and TEAM checklists. Pilots can help perceive hazards by using the PAVE checklist

of: Pilot, Aircraft, enVironment, and External pressures. They can process hazards by using the CARE

checklist of: Consequences, Alternatives, Reality, External factors. Finally, pilots can perform risk

management by using the TEAM choice list of: Transfer, Eliminate, Accept, or Mitigate.

Figure 10-3. Risk management processing can take place in any of three timeframes.

PAVE Checklist: Identify Hazards and Personal Minimums

In the first step, the goal is to develop situational awareness by perceiving hazards, which are

present events, objects, or circumstances that could contribute to an undesired future event. In

this step, the pilot will systematically identify and list hazards associated with all aspects of the

flight: Pilot, Aircraft, enVironment, and External pressures, which makes up the PAVE checklist.

[Figure 10-4] All four elements combine and interact to create a unique situation for any flight.

Pay special attention to the pilot-aircraft combination, and consider whether the combined

“pilot-aircraft team” is capable of the mission you want to fly. For example, you may be a very

experienced and proficient pilot, but your weather flying ability is still limited if you are flying an

unfamiliar aircraft. On the other hand, you may have a new technically advanced aircraft that you

have flown for a considerable amount of time.

Decision-Making in a Dynamic Environment

A solid approach to decision-making is through the use of analytical models, such as the 5 Ps, 3P, and

DECIDE. Good decisions result when pilots gather all available information, review it, analyze the

options, rate the options, select a course of action, and evaluate that course of action for correctness.

In some situations, there is not always time to make decisions based on analytical decision-making

skills. A good example is a quarterback whose actions are based upon a highly fluid and changing

situation. He intends to execute a plan, but new circumstances dictate decision-making on the fly. This

type of decision-making is called automatic decision-making or naturalized decision-making.
