On a 321, which doors would be disarmed during water operations?

• A. Doors 1 and 4
• B. All doors
• C. Doors 2 and 3
• D. None

Answer: (C)

In water operations, the way you arm or disarm doors is all about which exits will be used and how life rafts will be deployed. Doors that will serve as raft exits are kept armed, so their slides deploy as life rafts when needed. Doors that aren’t suitable for raft exits are disarmed to prevent accidental deployment and to simplify evacuation into the water. On an A321, the middle doors are the ones disarmed during water operations. The front and rear doors are the ones equipped with slides that convert to life rafts, so they stay armed for a ditching. This arrangement ensures passengers evacuate through the doors that will provide rafts and usable exits on the water, while the middle doors remain inactive.
