Q

What are WX settings for TO?

A

The AUTO mode is the default mode of the weather radar. The AUTO mode is adapted and optimized for all
flight phases. The flight crew can temporarily use the manual modes if needed, depending on the operational
context.

Q

Cockpit adjustable seats?

A

The CAPT and F/O seats are electrically powered in order move horizontally and vertically.
Manual controls enable crew to adjust the recline, the vertical and the horizontal position and the lumbar &
override the electrical controls, if necessary.
The third occupant’s seat is similar to CAPT and F/O seats but can only be adjusted mechanically.
The fourth occupant’s seat is a folding seat, and cannot be adjusted.

Q

What happens in case of pack overheat in
flight?

A

When the pack overheats the fault light in the PACK pb sw comes on. (Associated with the following ECAM
alert: AIR PACK 1(2) OVHT).
On the ground the active pack valve of a pack will automatically close, if the associated pack overheats.

Q

Bulk Cargo Ventilation?

A

The bulk cargo compartment has a heating system.
Some air from the cabin recirculates into the bulk cargo compartment for ventilation and temperature control.
An electrical heater heats the air that flows into the bulk cargo compartment.
Two isolation valves (manually controlled using the BULK ISOL VALVES pb-sw on the CARGO AIR COND pane)
permit the isolation of the bulk cargo compartment.
