A320 Reverser Unlocked
In the A320 the ENG 1(2) Shut Down checklist states that if 4 doors not stowed (CFM) or reverser deployed (IAE) If BUFFET For Ldg Use Flap 1 and if 1,2 or 3 doors not stowed or reverser detected unlocked Use Flap 3. Why this different configuration. Can someone please clarify?
