When the ALT‐NORM switch on the Audio Control Panel (ACP) is set to ALT:

The ACP switches to standby ACP and all functions operate normally except PA and interphone.

The ACP at that station is inoperative and the crewmember cannot communicate on any radios.

The ACP at that station is still operative but in degraded mode.

The ACP at that station is inoperative but the crewmember can communicate on one radio.

Correct! Wrong!

The cockpit voice recorder uses four independent channels to record flight deck audio for _____

300 minutes.

25 hours.

60 minutes.

120 minutes.

On the Audio Control panel (ACP) the Cabin call light comes ON. It will illuminate until:

Remains illuminated for 40 seconds.

Remains illuminated for 20 seconds.

Remains illuminated for 10 seconds.

Remains illuminated for 30 seconds.

Correct! Wrong!

With the Captain’s ACP operating in degraded mode, at that station:

VHF‐2 is the only useable radio.

Altitude alert, GPWS and windshear audio warnings are not heard.

The flight interphone remains useable, the PA is lost.

All ACP transmitter selectors remain functional, but receiver selectors are lost.

Correct! Wrong!

The call system is used as a means for various crewmembers to gain the attention of other crewmembers and to indicate that interphone communication is desired. Attention is gained through the use of lights and aural signals (chimes or horn). If the flight deck calls the cabin crew, the visual signal at called position is:

Green.

Blue.

Pink.

Blue then becomes red after 5 seconds.

Correct! Wrong!

The pilots can transmit directly over the flight interphone by using the control wheel PTT switch. Alternately, any crewmember with an ACP can transmit/receive over the flight interphone by using their related ACP and normal PTT switches. Any standard microphone may be used with the flight interphone system.

False.

True.

Correct! Wrong!

How are the communication systems controlled?

By the Audio Control Panel.

By their respective control modulators.

By the Mode Control Panel.
