FAA Airline Transport Pilot (ATM)Human Factors and CRMMedium
An airline crew is using the DECIDE model to resolve an in-flight decision about a hydraulic system caution light. After detecting the problem and estimating its significance, the next step in the model requires the crew to:
- ADo the necessary action
- BEvaluate the outcome of the action taken
- CChoose a course of action
- DIdentify alternative actions
Show answer & explanationAnswer & explanation
Correct answer: D. Identify alternative actions
The DECIDE model steps are Detect, Estimate, Choose, Identify, Do, Evaluate. After Detect and Estimate, the crew must Choose a desired outcome, then Identify alternative actions to achieve it, before Doing the action and Evaluating the effect.
Why the other options are wrong
- A. Doing the action comes after alternatives have been identified and selected.
- B. Evaluating the outcome is the final step, after action has been taken.
- C. Choosing the desired outcome actually comes immediately after estimating significance, before identifying alternatives.
DECIDE Model
A six-step aeronautical decision-making model used to help pilots systematically work through in-flight problems.
- Detect: recognize a change has occurred
- Estimate: determine the significance of the change
- Choose: select a desired outcome for the flight
- Identify: identify alternative actions to achieve the outcome
- Do: take the selected action
- Evaluate: assess the effect of the action taken
Memory trick: Detect, Estimate, Choose, Identify, Do, Evaluate — DECIDE it step by step
