The DECIDE model is a six-step method for pilots to make decisions in a logical manner.
The six steps of the DECIDE model are: Detect, Estimate, Choose, Identify, Do, and Evaluate.
1. Detect the problem
2. Estimate the need to react
3. Choose a course of action
4. Identify solutions
5. Do the necessary action
6. Evaluate the effect of the action
The DECIDE model is an alternative to methods such as the 3P (Perceive, Process, Perform) model.
