Since the beginning of time, humans have made mistakes. We eventually learned how to fly, but not how to avoid making mistakes. So how can we minimize the mistakes we make as pilots? And what are some of the warning signs that may lead to an error?
To safely pilot an aircraft, you require three primary skills:
It is important to note that these three aspects are interdependent. For example, outstanding ADM and aircraft knowledge will be of little use during an engine failure scenario if the pilot cannot control the aircraft. Conversely, excellent aircraft control will not benefit the pilot if they have no knowledge of the correct engine failure procedure. Furthermore, excellent aircraft control and knowledge will provide little help when the other engine fails after the pilot makes a poor decision to divert to an airport, not within range.
These are extreme examples, but they illustrate an important point: The often-overlooked process of ADM is detrimental to all other aspects of the flight.
The Federal Aviation Administration (FAA) defines ADM in AC 60-22 as: “A systematic approach to the mental process of evaluating a given set of circumstances and determining the best course of action”.
In other words: Using a system to make the best decision possible given your predicament.
As aviation became an increasingly large industry, it quickly became apparent that most accidents taking place were due in some part to human factors. Airlines realized that they could not simply rely on a crew’s experience to make good decisions. The search to find a solution culminated in the 1980s when operators introduced Crew Resource Management (CRM) training, and the results were remarkable.
In several independent studies, students were given specific ADM training and tested against their peers who did not receive ADM training. Strikingly, the students who received ADM training made between 10% – 50% fewer decision-making errors.
These studies prove the importance of ADM and that teaching ADM is possible.
The FAA defines a 3-P Model for implementing effective Aeronautical Decision Making:
This model allows pilots to improve their Aeronautical Decision-Making skills by applying a framework to any given circumstance.
The 3-P model consists of the following:
Examining these four elements will provide you with greater situational awareness, thus improving your decision-making:
Now consider the following as applied to PAVE:
Once you have perceived any possible hazards (PAVE) and determined the impact on the flight (CARE), you can now begin to decide on the most appropriate course of action:
Five primary attitudes negatively affect good Aeronautical Decision-Making:
It is vital that you immediately recognize if you begin to exhibit these attitudes and take action to prevent them from influencing your decision-making.
Now that we understand how to apply a model to our decisions and the attitudes and behaviors that are most likely to affect our decisions – Let’s look at some of the most common ADM errors.
After making a decision, humans tend to irrationally search for and favor information that confirms that the decision is correct. The “Reality” component of the 3-P model is beneficial towards decreasing confirmation bias.
The brain is very good at filtering the multitude of information presented to us at any given moment. Subconscious information filtering can be detrimental, however, as the pilot may filter important information. The “PAVE” component of the 3-P model can counteract this subconscious filtering of information.
The brain can use previous experiences to identify patterns and create expectations, which can cause issues if the assumptions are incorrect. For example, a pilot who transfers to a different Electronic Flight Information System (EFIS) may assume how the new system displays information based on their previous experiences with EFIS instruments. This assumption will lead to the pilot incorrectly interpreting information.

When incomplete information is presented to the brain, it will make assumptions about the missing information. As we saw in the previous example, assumptions can lead to dangerous situations. Optical illusions are an excellent example of dangerous assumptions the brain can make.
When considering your options, be careful of how you frame a statement, as this will influence your decision. For example, if you are on an unstable final approach, and you frame the “continue” statement as “If I don’t land, my passengers will be angry”, you may be biased towards continuing the approach. You should instead frame the statement, “If I continue this unstable approach, I may not be able to land”.
As human beings, errors in judgment and decision-making are inevitable, particularly in the aviation industry. We can, however, strive to minimize such mistakes by applying frameworks and models to guide decision-making and identify hazardous attitudes that may influence our decision-making.
Anyone can learn ADM, and it is a vital skill that every aviator should strive to master.
