Definition
In the context of checklist use, a three-step process is the standard method of working through a checklist item: read the item, perform the action, then verify that the action was completed correctly. Each step is distinct and must be done in order for the checklist to serve its safety purpose.
Plain English
A way of using a checklist where you read the item out loud, do what it says, then look or feel to confirm it actually got done. Three separate steps, in that order, every time.
Context Anchor
Seen in discussions about how pilots should use checklists before, during, and after flight.
Derivation
Process comes from a Latin word meaning “to go forward.” That helps here because the phrase means an ordered way of moving through checklist work, not a casual set of actions.
Why Pilots Care
Following this process reduces the risk of skipping critical steps and helps maintain consistent safety margins in every phase of flight.
Intuition Check
Do not read “three-step process” as just any three things done in a row. In this FAA context, it means a deliberate checklist method: do the actions, verify them with the checklist, and resolve anything not correct.
Example Sentence 1
His instructor reminded him that the three-step process means reading the item, performing the action, and then confirming the switch is actually in the position called for.
Example Sentence 2
During an emergency descent, the crew applied the three-step process to ensure every item on the checklist was addressed without omission.
