Definition
In the Three-P Model (Perceive, Process, Perform), Process is the second step, in which the pilot evaluates a perceived hazard by considering its impact on the flight, weighing the available options, and deciding on a course of action. It is the thinking and judgment stage that links what the pilot has noticed to what the pilot will actually do.
Plain English
After you spot something that could affect the flight, Process is when you stop and think it through: How bad is it? What are my choices? What am I going to do about it?
Context Anchor
Seen in aeronautical decision-making training, especially in the Three-P model: Perceive, Process, Perform.
Derivation
From Latin processus, meaning 'a going forward' or 'advance.' In aviation decision-making, it captures the idea of moving a problem forward in your mind — taking what you've noticed and working it through to a decision.
Why Pilots Care
It turns raw observations into deliberate, safer choices instead of impulsive reactions.
Intuition Check
Process does not mean paperwork or a fixed checklist here. In the Three-P model, it means the pilot’s mental evaluation of what a situation means for the flight.
Example Sentence 1

Example Sentence 2
