Illuminated - call to flight deck by attendant or ground crew. Accompanied by single high tone chime.
Vol 2 / 5.1.10 & 5.2.10
Explain the meaning of an illuminated Offside Tuning Light on the Radio Tuning Panel
Offside Tuning Light (white)
- The radio normally associated with this panel is being tuned by another radio tuning panel OR
- the radio tuning panel is being used to tune a radio not normally associated with this radio tuning panel
Vol 2 / 5.1.1
Explain how to activate and deactivate the Oxygen Mask Microphone
The oxygen mask microphone is enabled and the boom microphone is disabled when the right oxygen mask panel door is open.
The oxygen mask microphone is disabled and the boom microphone is enabled when the right oxygen mask panel door is closed and the TEST/RESET switch is pushed.
Note: The mask does not have to be stowed to enable normal communications.
Vol 2 / 5.2.4
Describe the Flight Interphone, Service (Attendant) Interphone, and Passenger Address Systems
Flight Interphone System:
- The flight interphone system is an independent communication network. Its primary purpose is to provide private communication between flight deck crewmembers without intrusion from the service interphone system. The ground crew may also use the flight deck interphone through a jack at the external power receptacle.
Service (Attendant) Interphone System:
- The service interphone system provides intercommunication between the flight deck, flight attendants and ground personnel.
Passenger Address System:
- The Passenger Address (PA) system allows flight deck crewmembers and flight attendants to make announcements to the passengers. The PA system use is prioritized. Flight deck announcements have first priority and override all others.
VOL 2 / 5.2.7 & 5.2.8 & 5.2.9
Describe the Flight Interphone System
Flight Interphone System:
- The flight interphone system is an independent communication network. Its primary purpose is to provide private communication between flight deck crewmembers without intrusion from the service interphone system. The ground crew may also use the flight deck interphone through a jack at the external power receptacle.
VOL 2 / 5.2.7
Describe the Service (Attendant) Interphone System
Service (Attendant) Interphone System:
- The service interphone system provides intercommunication between the flight deck, flight attendants and ground personnel.
VOL 2 / 5.2.8
Describe the Passenger Address (PA) System
Passenger Address System:
- The Passenger Address (PA) system allows flight deck crewmembers and flight attendants to make announcements to the passengers. The PA system use is prioritized. Flight deck announcements have first priority and override all others.
VOL 2 / 5.2.9
Describe the Operation of the Audio Control Panel (ACP)
Transmitter Selector (MIC SELECTOR) Switch: (talking, rectangle lights)
- Illuminated - related switch is active
- Only one switch may be selected at a time; pushing a second switch deselects first switch
- Reception is possible over the selected system regardless f whether the related receiver switch is on
SELCAL Light (a “C” in bottom of Transmitter selector):
- Illuminated - accompanied by chime, alerts crew, communication is desired on indicated communication radio
- Will automatically reset when microphone is keyed, control wheel MIC switch is pressed or R/T - I/C switch is positioned to R/T
Receiver Switches: (listening round lights)
- Illuminated (white) - related switch is active
- Multiple switches may be selected
Alternate-Normal (ALT-NORM) Switch:
- NORM (Normal) - ACP operates normally
- ALT (alternate) - ACP operates in degraded mode
VOL 2 / 5.1.2
Describe the Degraded Audio System operation
Audio system operation can be switched to a degraded mode by placing the ALT/NORM switch to ALT. In this mode, the ACP at that station is inoperative and the crewmember can only communicate on one radio.
The radio available to each crewmember station is:
- Captain: VHF-1
- First Officer: VHF-2
- Observer: VHF-1
Note: the mask and boom microphones can be used for transmission on the usable radio. The hand microphone is not usable in the degraded mode of operation. An audio system operating in the degraded mode cannot access the passenger address system through the ACP.
NO PAs in degraded mode!
VOL 2 / 5.1.2 & 5.2.6
Explain the function of the SERVICE INTERPHONE switch
OFF - external jacks are deactivated. Communication between the flight deck and flight attendants is still possible
ON - add external jacks to service interphone system
Captains always wanted these off so no one could “listen in on flight deck convo”… what you saying that you shouldn’t be saying, bro?
VOL 2 / 5.1.8
The offside tuning light on the radio tuning panel may indicate…
that the radio tuning panel is being used to tune a radio not normally associated with this tuning panel
ESV-VA: Communications
Does the oxygen mask need to be stowed in the stowage box to disable the oxygen mask microphone?
No, but the right oxygen mask panel door must be closed and the RESET/TEST switch must be pushed.
You could be wearing that bad boy and close the doors of the box, hit reset and it will still disable the mic in the mask that you’re wearing
ESV-VA: Communications
An illuminated Transmitter Selector (MIC SELECTOR) switch on the audio control panel indicates…
select all that apply
- the related switch is active
- reception is possible over the selected system regardless of whether related receiver switch is on
ESV-VA: Communications
An incoming call from the attendant or ground crew is indicated by a:
select all that apply
- Single high-tone chime
- Call light on the forward overhead panel
ESV-VA: Communications
Service interphone or PA communcations to the cabin can be made with the:
- All of the above
- Handset
- Boom microphone
- Hand microphone
I have no idea which one is which in this situation when it comes to headset, the mic on the center console and the mic on the right side of the plane
