5.1 Philosophy

Checklists are used to verify actions, not to perform them.

All procedures follow the principle:

👉 FLOW → CHECKLIST

• Flow: Memory-based actions performed in a logical sequence
• Checklist: Verification that all required items are correctly set

Core Rule

“The flow sets the aircraft – the checklist verifies it.”

General Rules

• Checklists are performed by PM
• PF confirms critical items when required
• No checklist is performed during high workload phases unless required
• Interruptions → checklist must be restarted
