The fourth occupant’s oxygen mask microphone is not usable.

Question 7

When does the flight crew know that an incoming message was received via ACARS?

Answer 7

If an incoming message is received via ACARS, the ACARS MSG memo appears accompanied by an aural buzzer.

Question 8

ACARS can downlink and uplink information tailored to each operator, including:

Answer 8

• Flight times
• Performance data
• In-flight progress reports
• Weather information

Question 9

What is the purpose of the CIDS?

Answer 9

There are two Cabin Intercommunication Data Systems (CIDS), either of which are capable of controlling the following:
* PA system
* General cabin illumination and signs
* Lavatory smoke detection and indications
* Emergency evacuation signaling
* Passenger entertainment system
* Escape slide bottle pressure monitoring
* Vacuum system control function
* Cargo compartment and lavatory smoke detection
* Cabin and Service interphone systems

An ECAM message is only triggered if both CIDS fail.

Question 10

There are three interphone systems:

Answer 10

• Flight - Flight deck to pushback coordinator
• Cabin - Flight Deck to cabin
• Service - Allows communications between all receptacles to facilitate maintenance operations

Question 11

When a flight attendant station pb on the CALLS panel is pressed:

Answer 11

• A high-low chime sounds in the corresponding section of the cabin
• Two pink lights on the cabin CALLS panel illuminate in the related area
• The message, CAPTAIN CALL, appears on the Attendant Indication Panel (AIP), accompanied by a green light

Question 12

When the EMER pb is pressed on the CALLS panel:

Answer 12

• The white ON and amber CALL light will flash on the pb
• The cabin chime will sound 3 times on all cabin loudspeakers
• Two pink lights flash at all area CALL panels
• EMERGENCY CALL appears in red on all AIPs, accompanied by a red light

To reset an emergency call, the flight attendant must press RESET before hanging up the handset.

Question 13

What occurs when the MECH pb is pressed?

Answer 13

When the MECH pb is pressed, an external horn sounds at the panel area for as long as the MECH pb is held and a blue COCKPIT CALL light illuminates until reset by ground personnel.

Question 14

The single buzzer for a normal cabin call and the three buzzers for an emergency cabin call are inhibited on takeoff below _____’ and on approach below _____’ until touchdown. The flashing CALL light still illuminates.

Answer 14

1500’, 800’

Question 15

The CVR system consists of:

Answer 15

• A remote microphone
• A hot mic function
• A crash proof four-track recorder equipped with an underwater locating beacon
• A control panel located on the overhead panel

Question 16

The CVR records and retains:

Answer 16

• Conversations on the flight deck
• Flight deck aural warnings
• Radio communications
• Interphone conversations between crew members
• Announcements transmitted over the PA

Question 17

The DFDR shares the same circuitry and is activated whenever the CVR is activated. Both systems are activated under the following conditions:

Answer 17

• For 5 minutes after the aircraft’s electrical system is energized
• After the first engine is started
• Whenever the aircraft is in flight
• On the ground, they are automatically de-energized 5 minutes after the last engine is shutdown

Question 18

What does the CVR ERASE pb accomplish?

Answer 18

To erase the entire 30 minutes of the CVR, the CVR ERASE pb must be pressed for at least 2 seconds on the ground with the parking brake set.

Question 19

What does the COMMAND pb accomplish?

Question 20

When would the external horn sound?

Answer 20

• When the MECH pb is pressed
• ADIRS ON BATT
• Avionics Low Pressure Duct

Question 21
