A320 Doors Questions

Opening a passenger door from the outside disarms the door and the escape slide.

• True.
• False.

Explanation: Each passenger door's escape slide is only armed for automatic deployment when the door is opened from inside; opening it from the outside disarms both the door mechanism and the slide so it can't inflate.

If door handle is lifted and the white indicator illuminates, what does this mean?

• The escape slide is armed and if you go on lifting the handle, door opens and slide will deploy.
• Pneumatic assistance of the door has failed
• The escape slide is in disarmed configuration
• The cabin is still pressurized

Explanation: Each passenger door has its own warning light showing the ARMED/DISARMED state of its escape slide; a white indicator with the handle lifted shows the slide is armed, and continuing to lift the handle fully opens the door and triggers automatic slide deployment.

When opened in an emergency, the passenger entry doors:

• Pneumatically assisted into the open position
• Will need two cabin crew to push them open
• Are assisted to the open position by slide inflation
• Are electrically assisted into the open position.

Explanation: Each passenger door has a damper actuator that, in an emergency, drives the door's automatic opening rather than requiring the door to be pushed open manually or relying on the slide itself to move it.

When the Cargo door switch for the yellow hydraulic pump is in use, the flight controls are:

• Fully operational
• Inhibited
• Hydraulically locked by pressure from the electric pump
• Only operated by the green system.

Explanation: Opening a cargo door pressurizes the yellow system through the dedicated electric pump specifically for that task, and while it's running the flight controls (and the PTU) are inhibited from operating on yellow pressure.

• It operates normally on HOT BAT bus.

Can the flight compartment sliding windows be used as emergency exits?

• Yes, in the cockpit coat closet is a rope ladder that can be used in such an event.
• Yes, there are escape ropes mounted above each window behind an access panel.
• No. They are not approved emergency exits.
• No, they are too small.

Explanation: Each cockpit sliding window has a small compartment above it containing an escape rope long enough to reach the ground, making the sliding windows usable as flight-crew emergency exits.
