The bulk cargo compartment is _______ ventilated.

Correct! Wrong!

The batteries are ventilated during the flight by _______ that is extracted and discharged overboard via differential pressure.

Correct! Wrong!

The avionics ventilation system cools the electrical and electronic equipment in the avionics bay and in the cockpit panels.

Correct! Wrong!

There are ____ avionics ventilation circuits:

Correct! Wrong!

In some cabin areas (e.g. lavatories, galleys) to avoid bad smells, air is extracted and then directly discharged:

Correct! Wrong!

On ground, two blowing fans ventilate both pack bay areas. Bleed air, from any available bleed supply, flows through two supply valves and drives both fans. The ASCU controls the blowing fans that are:

Correct! Wrong!

The forward and aft cargo compartments are automatically ventilated, with air from the air-conditioning system. Air flows into the cargo compartments, via:

Correct! Wrong!

There are two blowing fans, that blow recirculated air from the cabin in the various cockpit panels and electronic equipment. Each avionics ventilation circuit has one blowing fan. For both avionics ventilation circuits, the air is first filtered, before it enters the blowing fan.

Correct! Wrong!

In flight, when the AVNCS EXTRACT pb-sw on the VENT panel is set to OVRD: the overboard valve partially opens, and air is extracted and discharged through the overboard valve and inboard valve. The inboard valve remains closed only if the extract fans are running.

Correct! Wrong!

The inboard valve remains OPEN only if the extract fans are running!

The batteries are ventilated on ground by cabin air that is extracted and discharged overboard via differential pressure.

Correct! Wrong!

The batteries are ventilated during flight

The cockpit is automatically ventilated, with air from:

Correct! Wrong!

On ground, the avionics ground cooling system cools the air that is blown in the avionics bay and the cockpit panels. The ground cooling system has two units, one for each avionics ventilation circuit. The two units operate independently. When the GND COOLG AVNCS pb-sw is set to AUTO, the ground cooling system will activate automatically if the temperature of the air is too high, and the air conditioning is OFF. This occurs when Air temperature is:

Correct! Wrong!

The electrical heater is at HIGH power. The electrical heater increases the temperature of the airflow which goes to:

Correct! Wrong!

If necessary, the flight crew can manually force the cockpit ventilation.

Correct! Wrong!

Each flight crew can manually adjust the airflow which goes around the onside rudder pedals. The airflow is adjusted with the FOOT VENT selector on the onside CAPT(FO) INDIVIDUAL VENT panel but the temperature of this airflow cannot be increased.

Correct! Wrong!

There are _____ recirculation fans that recirculate cabin air to the mixer unit

Correct! Wrong!

When the electrical heater switch is at HIGH power, it increases the temperature of the airflow which goes to:

Correct! Wrong!

If the electrical heater is at LOW power, it delivers:

Correct! Wrong!

A ventilation system cools the two pack bays, and is fully automatic. The pack bay areas are ventilated by external air. In flight, external air flows into each pack bay area, through an air inlet. Both air inlets are:

Correct! Wrong!

Avionics Ventilation - The recirculated air is discharged overboard, when:

Correct! Wrong!

Each avionics ventilation circuit has one backup valve. If the blowing fans cannot correctly cool the avionics bay, the backup valve of the affected circuit automatically opens. This enables air from the air conditioning system, to cool the avionics systems.

Correct! Wrong!

Avionics ventilation - Each ventilation circuit has _______ . If the blowing fans cannot correctly cool the avionics bay, the backup valve of the affected circuit automatically opens. This enables air from the air conditioning system, to cool the avionics systems.

Correct! Wrong!

The backup valve opens if the associated blowing fan fails / if the airflow in the ventilation circuit is not sufficient. For example: the associated filter is clogged.

Pack bay ventilation - The pack bay areas are ventilated by external air.

Correct! Wrong!
