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
