5.1 Philosophy
Checklists are used to verify actions, not to perform them.
All procedures follow the principle:
π FLOW β CHECKLIST
- Flow: Memory-based actions performed in a logical sequence
- Checklist: Verification that all required items are correctly set
Core Rule
βThe flow sets the aircraft β the checklist verifies it.β
General Rules
- Checklists are performed by PM
- PF confirms critical items when required
- No checklist is performed during high workload phases unless required
- Interruptions β checklist must be restarted
