Definition
Models in aeronautical decision-making that describe how pilots actually make decisions in real flying situations, based on observation of their behavior, rather than how they ideally should. Descriptive models capture the practical, often shortcut-based ways pilots assess situations and choose actions, including the role of experience, recognition of familiar patterns, and intuition.
Plain English
These are models that show how pilots really think and decide when flying — not the textbook ideal, but what actually happens in the cockpit. They describe the real, sometimes messy, process pilots use, especially when time is short.
Context Anchor
Seen in aeronautical decision-making discussions, especially when studying how pilots recognize risks, choose actions, and learn from past decisions.
Derivation
From the Latin describere, meaning 'to write down' or 'to set out in detail.' A descriptive model sets out what is observed, in contrast to a prescriptive model, which sets out what should be done.
Why Pilots Care
Recognizing these models helps pilots identify their own decision patterns, reduce errors from mental shortcuts, and improve safety during high-workload or unexpected situations.
Grounding Statement
A pilot deciding whether to continue, divert, or delay because the weather is changing is using real-world judgment, not solving a perfect classroom problem.
Intuition Check
Descriptive does not mean “more detailed” here. It means “describing what people actually do,” not “telling them the one best answer.”
Example Sentence 1
The instructor used descriptive decision-making models to show how experienced pilots often rely on pattern recognition rather than working through every option.
Example Sentence 2
By studying descriptive decision-making models, the student pilot learned why experienced aviators sometimes skip steps when facing familiar emergencies.
