A320 Equipment Questions

On the cockpit overhead panel there is a three position EMERGENCY EXIT LT switch. What lights are associated with this switch?

• Exit signs, emergency lights, and floor path lights.
• Exit signs, emergency lights, main panel flood lights, and floor path lights.
• Exit signs, emergency lights, dome lights, main panel flood lights, and the standby compass light.
• Exit signs, and the standby compass light.

Explanation: Setting the cockpit EMER EXIT LT switch to ON brings on the overhead emergency lights, the EXIT signs, and the floor proximity escape-path marking system together — it isn't tied to the main panel flood lights, dome lights, or the standby compass light, which are separate cockpit-lighting circuits.

The PBE provides a breathable atmosphere for approximately ______ minutes.

• 10
• 15
• 16
• 18

Explanation: The PBE hood is rated to operate for at least 15 minutes, giving a breathable atmosphere for that duration.

Oxygen - Portable Oxygen System (Flight Crew's Portable Oxygen System)

There is no other way of deploying the overwing escape slide if it fails to deploy automatically on opening the emergency exit.

• True.
• False

Explanation: The escape slide's automatic inflation is backed up by a manual option — if the inflation bottle fails to discharge on its own, a crew member can open its valve directly to trigger deployment, so an automatic-deployment failure isn't the end of the line.

How is crew oxygen provided?

• From a single bottle.
• There is one bottle per crew member except for jumpseaters
• Oxygen generator.
• One oxygen bottle with an oxygen generator.

Explanation: The cockpit's fixed oxygen system is built around a single high-pressure cylinder feeding a shared distribution system, supplying all of the crew's quick-donning masks from that one bottle — not one bottle per crew member.

The HALON fire extinguisher should be used on what type fires?

• Electrical fires only.
• Electrical and burning metals.
• Electrical and flammable liquid fires
• Electrical and ordinary combustibles.

Explanation: Halon extinguishers are rated for electrical fires and flammable-liquid fires — they aren't the right choice for ordinary combustibles or burning-metal fires, which need different extinguishing agents.

When the door arming lever is in the ARMED position, opening the door from the outside will:

• Automatically deploy and inflate the evacuation slide.
• Disarm the door.
• The power assist will rapidly open the door.

Explanation: With the door arming lever in ARMED, opening that door from the outside disarms the door and its escape slide — the slide doesn't inflate in that case, since automatic deployment is only tied to opening the door from inside.

Opening an emergency overwing exit will:

• Inflate the slide at the leading edge of the wing.
• Automatically inflate the double lane slide off the trailing edge of the wing.
• Only arm the overwing slide.

Explanation: Opening an overwing emergency exit automatically deploys its dual-lane escape slide off the wing's trailing edge — the overwing slide is kept in a permanently armed configuration, so no separate arming step is needed.

What cockpit lighting is available during an Emergency Electrical Configuration (EEC)?

• All lights are fully functional.
• Dome lights, main panel flood lights, and the standby compass light.
• Dome light (right side only), main panel flood lights, and the standby compass light.
• Dome light (right side only), main panel flood lights (left two columns only), and the standby compass light.

Explanation: On battery-only power in the Emergency Electrical Configuration, cockpit lighting is reduced to just the right-side dome light, the main panel flood lights covering the left two columns only, and the standby compass light — not full lighting.
