Aeronautical Decision-Making (ADM)

Aeronautical Decision-Making (ADM) is the systematic approach to the mental process used by pilots to consistently determine the best course of action in response to a given set of circumstances. The FAA defines ADM in the Pilot’s Handbook of Aeronautical Knowledge (PHAK), Chapter 2, as a structured process that goes well beyond simply knowing regulations or completing checklists.

At its core, ADM recognizes that aviation accidents rarely result from a single catastrophic failure. Instead, most accidents trace back to a chain of poor decisions, often made under time pressure, incomplete information, and competing priorities. ADM provides pilots with a framework to interrupt that chain before it leads to an unsafe outcome.

The concept was formalized by the FAA in the 1990s after extensive research into human factors and crew resource management. It has since become a foundational element of pilot training at every certificate level, from student pilot through airline transport pilot.

One of the most important lessons of ADM is that good decision-making is not about finding the single “correct” answer. In most real-world flying situations, multiple options may be reasonable. The distinguishing trait of a skilled pilot is the ability to recognize risk early and choose the option that preserves the most alternatives for the future.

Conservative decisions—such as diverting before weather deteriorates, canceling a flight when conditions are marginal, or adding extra fuel—are often inconvenient. They may cost time, money, or social standing. But they consistently produce better safety outcomes. The FAA’s Risk Management Handbook emphasizes that a safe arrival after a risky decision does not validate the decision. Outcome bias—judging a decision by its result rather than its process—is one of the most dangerous traps a pilot can fall into.

SkeyeMentor’s Scenario Lab is designed to teach this principle directly. Every scenario involves tradeoffs, competing pressures, and incomplete information—just like real flying.

The FAA describes ADM as a continuous cycle, not a one-time checklist. Pilots should be constantly evaluating and re-evaluating their situation throughout every phase of flight. The general ADM process includes these steps:

1. Identify the hazard. What has changed? What could go wrong?

2. Assess the risk. How likely is the hazard to affect the flight? How severe would the consequences be?

3. Evaluate alternatives. What options are available? What are the tradeoffs of each?

4. Make a decision. Choose the option that best manages risk while preserving future alternatives.

5. Act. Implement the decision promptly.

6. Reassess. Did the action produce the expected result? Has anything else changed?

This cycle mirrors more structured frameworks like the DECIDE model and the 3P (Perceive–Process–Perform) model described in the Risk Management Handbook.

Research into aviation accidents has identified several recurring patterns of poor ADM:

• Plan continuation bias — Continuing with the original plan despite evidence that conditions have changed. This is the single most common factor in weather-related general aviation accidents.

• Get-there-itis — An overwhelming desire to reach the destination, often driven by external pressures such as schedule commitments, passenger expectations, or sunk costs.

• Confirmation bias — Seeking out information that supports the decision you’ve already made while ignoring contradictory evidence.

• Overconfidence — Believing that experience alone protects you from risk, particularly after a long period without incidents.

• Complacency — Relaxing vigilance during familiar or routine operations, leading to missed hazards.

The Scenario Lab’s debrief system is designed to surface these patterns when they appear in your decisions.

The FAA teaches several structured ADM frameworks that pilots can apply in real time:

• PAVE — A preflight risk-assessment checklist evaluating Pilot, Aircraft, enVironment, and External pressures.

• IMSAFE — A personal fitness self-assessment: Illness, Medication, Stress, Alcohol, Fatigue, Emotion/Eating.

• DECIDE — A six-step in-flight decision model: Detect, Estimate, Choose, Identify, Do, Evaluate.

• 5P Model — Plan, Plane, Pilot, Passengers, Programming—a broader situational awareness tool.

• Hazardous Attitudes — Five psychological tendencies (anti-authority, impulsivity, invulnerability, macho, resignation) with specific antidotes.

No single framework covers every situation. Effective ADM involves selecting and applying the right tool for the current circumstances. The Scenario Lab teaches all of these in context, so you learn when and how each framework applies.
