Cabin System Q’s Flashcards
A leaky line antenna for an inflight system
Sends and receives signal for PED
A cabin network service enables
Pax to access internet and email services via a WLAN
Leaky line antenna exhibits a highly directional field with a
Highly concentrated radiation distribution within then cabin
Conference call on on the cabin interphone may
Be interrupted by the captain or purser
Pax database maybe hosted on the
Cabin network service
A pax ife system would be expected to incorporate
Pa intercom connection
Access to pre departure/departure reports maybe made by cabin crew via the
Cabin network service
In event of cabin decompression
Ife automatically switches to standby mode
Aircraft ife systems where all users selectable content is stored in the seat is known as
Seat centric
LCD backlighting on a personal television changes
With the level of cabin lighting
A electronic library system is a
General purpose computing platform intended to reduce or replace paper based reference material used by the flight crew
Leaky line attenuation over the length of the cabin can be significant and affect signal strength how is attenuation prevented over the cable length
Shielding screens are placed in the gaps between slots
An emergency crew and alerting system is used
Either by the cockpit to alert the cabin crew of a cockpit incident or by the cabin crew to alert the pilot of a cabin incident
An IFE tapping unit
Decodes video signals for the LCD monitors
An IFE centre is most likely installed
In the avionics bay
An inflight mobile phone system
Uses satcom to send signal to ground base
And interface between cockpit/cabin crew and cabin systems is performed via a data exchange or different related LRUs and is magaed by
Cabin intercommunication data system cIDS
Cabin core lighting system has a complete failure
Lights go to default brightness
Cabin surveillance video is displayed
Both in the cockpit and also in the cabin on designated FAPs
CIDs audio includes
Passenger address and cabin interphone
Data/radio communications within the cabin typically interface with the
Cabin network service
Dial and call information from the PA and interphone is displayed to the cabin attendants on the
Attendant indication panels
Electric window shades on the cabin can be controlled
From the FAPs
Flight attendants communicate with the directors of the cabin intercommunication data system using
FAPs within the cabin
If a cabin config is changed or an additional cabin service is added to the cabin systems
Only the cabin intercommunication data systems software needs to be updated
If a CIDs director fails what would be affected
Nothing
If a CIDs director fails what functions will be affected
None the second or third director will take over
If additional multipurpose FAPs need to be fitted in a cabin system they are
Daisy chain connected to the existing FAPs
If cabin chime indications are inhibited the inhibit function is reset
When the aircraft transits from flight phase to landing phase
If the emergency evacuation command button is operated in the cockpit it can be cancelled (reset)
Either by the cabin crew at the cabin crew stations or the flight crew in the cockpit
In an IFE system the supply of network data interactive data passenger service data and database information is provided to each seat from the area distribution box via
Fibre optic or Ethernet cable
In the CIDs if one loudspeaker does not work what will happen
It will have no effect on
In the PA system an announcement being made on the cabin handset would be interrupted if another announcement was initiated on the
Cockpit
Interested PRAM is stored
On a compact flash card on the FAP
Interactivity between cabin crew and CODs director is provided by
FAPS and MFAPS
Loud speaker level adjustment for announcement and chimes from the cabin intercommunication data system can be adjusted
Either on the ground or in flight
Misc cabin systems such as loud speaker volume level adjustment crew signalling and emergency evacuation can be controlled from the cabin via
FAPs
Most video used on IFE AVOD systems use which compression encoding standard
MPEG
Much of the cabin layout definition and other airline specific data such as cabin zoning chime sequences and default audio levels are stored on
The plug in cabin assignment module incorporated on the FAP
On modern aircraft cabin system equipped with a CIDs the CIDs interfaces with the air conditioning system
Via the ADCN
On a modern aircraft cabin system equipped with a CIDS a pax call can be reset
At the attendants station via the FAP
On a modern large pax aircraft the provision of email intranet internet access is hosted on the
Cabin network service
On a aircraft fitted with CIDS the return to seat and fasten seat belts signs are auto illuminated when the fasten seat belts control is in auto mode and
Landing gear is down and locked
On a aircraft fitted with CIdS the cabin temp control is controlled and monitored
By the aircraft’s ECS independently from CIDS
In a aircraft fitted with CIDS the lav smoke warning and indication is controlled and monitored
By the CIDS system
Output from the cockpit acoustic devices
Are never interrupted by other audio sources
Passenger laptops are connected to the seat IFE
RJ45 plug
The cabin and flight interphone system
Allows the communication via telephone between all attendant stations and between the attendant stations and the cockpit
The cabin core system
Hosts the IFE system
The cabin made memory system
Used to store and process cabin related data such as system configuration data and multimedia programs
Cabin monitoring system includes only those surveillance cameras and monitors for monitoring the
Cabin interior
The call system for the captain will have the audio signal of a
Two tone chime
Central processing functions of the CIDs is contained within the
Directors
The FAP indicates
Waste/Water levels light status
The function of the CIDs are programmed configured and controlled via the
FAPs
The interface between a CIDs directors and the pax related functions such as cabin lighting and psus is
Décoder encoder units which there are many in the cabin
Landscape camera system can be deactivated remotely from the camera module
From the switch located on the exterior of the aircraft
The PA system
Distributes announcements from the cockpit and each attendant station through all assigned pax loudspeakers
Seat belt sign switch must be positioned in the cockpit so that
Both captain and first officer can operate it
The service interphone system
Allows the communication via telephone between the ground crew the cockpit crew and the cabin crew when the aircraft is on the ground
The units and components which furnish a means of entertaining the pax on a modern aircraft include
Video screens audio outlets and internet connectivity
Various indicating functions for the cabin systems are achieved via the
FAPs
What incident will put the ife system into standby mode automatically
Cabin decompression
When more than one directors is fitted to fulfill the role of the controllers within a CIDs
One of the directors in active mode and the others are in hot standby mode
Where is the OBRM located
Attached to the FAPS
WiFi provision to pax is
Provided via sat link when not over land
