Flashcards in Intergrated Modular Avionics Deck (36):
1

Due to the new avionics concept, where are most of the conventional LRU functions performed?

In Avionics Applications

2

What does each CPIOM use?

new hardware and software technologies and hosts these independent applications in the same computing and memory resource

3

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.

4

What units in IMA are LRMs?

IOMs and CPIOMs

5

How is communication between the LRMs performed?

They communicate through the ADCN via AFDX technology

6

How many types of CPIOMs exist?

7

7

Are CPIOMs interchangeable?

They are interchangeable but may require software reconfiguration

8

What does each CPIOM host?

An avionics application

9

What are the various components of a CPIOM?

Hardware Boards, Field loadable module software and a field loadable avionics database.

10

What does the hardware of a CPIOM consist of?

A power board, 2 I/O boards and 1 CPU board

11

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

12

What is the ATA software composed of?

One or more avionics applications and may include one or more database

13

Which board of the ADCN enables the AFDX interface with the ADCN?

The CPU or End System Board

14

How is a CPIOM connected to the aircraft systems?

Through 2 I/O boards that use analogue, ARINC, CAN or discrete signals.

15

What is the software of CPIOM-Bx?

Air Conditioning

16

What is the software of CPION-Dx

Data Link

17

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.

18

How many IOMs are there?

25

In the ADCN the aircraft systems are organized into?

7 functional areas

26

What is each functional area of an ADCN composed of?

LRUs, IOMs, CPIOMs, and LRUs with AFDX technology

27

How is data exchange in the avionics world mostly performed?

Through the ADCN via AFDX technology
