102 Inter-Communication System Flashcards
Discuss how ICS functions (17 cards)
What is the Nomenclature of the ICS System?
AN/AIC-32.
What is the Purpose of ICS?
Provide Secure or Clear low crosstalk communications from station-to-staion and from station-to-radio.
Explain how ICS Supports Flight Deck in an Emergency
ICS provides backup radio assignments to each seat in the flight deck.
Pilot: V/UHF 1
Flight Engineer: V/UHF 2
Co-Pilot: V/UHF 3
Nav: HF 1
When Shall Seat 1 be Connected to Mission Area CSU?
- During all challenge and response checklists
- Any phase of flight below 10,000 feet
- In the event of DVS failure
How Many CSU’s are on Block II Modified E-6B’s?
6 in total.
- 4 in Flight Deck (and one Emergency Audio Panel)
- 1 in Comm Central Position 18 (and one Auxilary Contrul Unit)
- 1 in Reel Operator Station
What is the Function of a CSU?
Allow operator’s to interface with internal and external communications equipment.
In Addition to the CSU at Postion 18, What Component Expands Radio Selection for the CCU?
The Auxilary Control Unit or ACU. Allows selection of V/UHF 1, 2, 3, and HF 1.
What is an MSU and What Does it Provide?
Maintenance Service Unit; primarily used by maintenance personnel or during the Reel Operator/Plane Captain during aircraft launch and recovery.
How Many MSU’s are Located on the E-6B?
8 MSU’s in total.
- 3 in Forward Lower Lobe
- 2 in Aft Lower Lobe
- 1 above Position 9 in BTSF
- 2 in Aft Mission Compartment with one on each side of jet
What is Considered the “Brains of ICS”?
The Communications Control Unit or “CCU”. Serves as the central “computer” of ICS.
How Many Modes Does the CCU Have and how can you interface with them?
Three modes; primary, secondary, and backup. They can be interfaced via the Palomar GUI on the MAPS application or the Emergency Audio Panel in flight deck.
Explain why the CCU is Critical to the Operation of ICS
The CCU controls the flow of communication between internal and external communications.
What is the function of the Radio Select/Emergency Audio Panel?
The RS/EAP is a secondary interface for the CCU, allowing flight deck to swap CCU into backup mode in case of Primary or Secondary failure. It also provides selections to connect VHF Data Link voice channels (VDL), SATCOM (INMARSAT), or HF-3 to ICS.
What is the Emergency Audio Junction Box?
The copilot’s headset jack panel is also the EAJB assembly, it interconnects all flight deck audio streams when copilot activates the ALL LISTEN switch.
In the Event the CCU Detects a Failure, How Does the PA Operate?
The PA will operate in backup mode automatically. The emergency audio switch may be used to activate the emergency PA if necessary.
What is the Emergency Audio Switch’s Purpose?
It activates/deactivates emergency communications. It breaks the connections with ICS ports and places other Flight Deck headsets in parallel with copilot headset’s audio for LISTEN only.
What is the ICS Palomar GUI?
The primary interface software for the CCU.
