Intergrated Modular Avionics Flashcards
Due to the new avionics concept, where are most of the conventional LRU functions performed?
In Avionics Applications
What does each CPIOM use?
new hardware and software technologies and hosts these independent applications in the same computing and memory resource
What does an IOM enable?
An Input/ Output module converts non-AFDX data that is from conventional LRUs into AFDX data used within the ACDN.
What units in IMA are LRMs?
IOMs and CPIOMs
How is communication between the LRMs performed?
They communicate through the ADCN via AFDX technology
How many types of CPIOMs exist?
7
Are CPIOMs interchangeable?
They are interchangeable but may require software reconfiguration
What does each CPIOM host?
An avionics application
What are the various components of a CPIOM?
Hardware Boards, Field loadable module software and a field loadable avionics database.
What does the hardware of a CPIOM consist of?
A power board, 2 I/O boards and 1 CPU board
What are the components of field loadable module software?
A CORE SOFTWARE that operates the module and its hosted applications and a CONFIGURATION TABLE SOFTWARE
What is the ATA software composed of?
One or more avionics applications and may include one or more database
Which board of the ADCN enables the AFDX interface with the ADCN?
The CPU or End System Board
How is a CPIOM connected to the aircraft systems?
Through 2 I/O boards that use analogue, ARINC, CAN or discrete signals.
What is the software of CPIOM-Bx?
Air Conditioning
What is the software of CPION-Dx
Data Link
What does an IOM enable?
An IOM converts non-AFDX data that is from a conventional LRU into AFDX data to be used in the ADCN.
How many IOMs are there?
8 connected using AFDX technology.
If one IOM is lost what is the result in communication?
No communication is lost
What are the components of a IOM?
Hardware Boards, Field Loadable Software
What is the loadable software into an IOM?

Are IOMs interchangeable?
All IOMs are fully interchangeable
In the ADCN the aircraft systems are organized into?
7 functional areas
What is each functional area of an ADCN composed of?
LRUs, IOMs, CPIOMs, and LRUs with AFDX technology
How is data exchange in the avionics world mostly performed?
Through the ADCN via AFDX technology
How many networks does the ADCN comprise of?
2 redundant networks, A and B.
At which speed to ADCN subscribers communicate?
10 - 100 Mbps
What does the routing of a virtual link depend on?
Receivers
What is the function of an AFDX switch?
It receives the VL coming from one emitter and routes it to the appropriate output ports based on the configuration table.
What are the components of an AFDX switch?
Hardware boards and Field loadable software
What are the hardware boards of an AFDX switch?
