NEW AVIONICS REFERENCES

One of the problems in learning the new avionics, i.e ATA 42, 44, 45 and 46 is to get a suitable reference or notes. For that reason, I rely on the internet to get the note from Airbus and Boeing. In most cases, I prefer to search for A380 note.

Here are the example:
A. ATA 42 - Integrated Modular Avionics

a. I will search for "A380 ATA 42 note"

This is what I get....

The information is enough to get me started.

AFDX and IMA

IMA or integrated modular avionics is one of the four new avionics ATA for modern aircaft. IMA or integrated modular avionics is under the ATA 42, used by A380 and later aircraft.

AFDX is the data communication network utilized in the IMA system. Of course, there are other data network, such as ARINCS 429, 629 utilised in the IMA system, but AFDX was specifically designed to meet the IMA requirement. The AFDX is specified in the ARINC 664 part 7.

To assist in learning about AFDX, I include some links.

ATA 44 CABIN SYSTEM

I faced challenges to conduct courses on the ATA 44.

To start with, this is a new ATA, and not many references are available. If you were to check the aircraft's ATA, there are not many aircraft types using ATA 44.  This forced me to select A380 as the reference module.

The reference are readily available in the internet.

This as an example..

 I was using four reference to prepare the course...

1. Airbus training manual
2. Airbus Maintenance Manual
3. Flight Crew Manual
4. Crew guides

TRANSFORMER

Transformer is included to module 3. The syllabus is as follows...

3.15 Transformers (L2)
Transformer construction principles and operation;
Transformer losses and methods for overcoming them;
Transformer action under load and no-load conditions;
Power transfer, efficiency, polarity markings;
Calculation of line and phase voltages and currents;
Calculation of power in a three phase system;
Primary and Secondary current, voltage, turns ratio,power, efficiency;
Auto transformers.

I have included a short youtube video, It is noted that the video does not cover the whole syllabus...





I intend to add more contents

Integrated Modular Avionics (IMA)

This is one of the 4 new ATA chapters. The IMA is under 42.

A. INTRODUCTION

The DCAM syllabus gave a lengthy write up. I believe, this was done as the subjects were new and not many were familiar. I would divide the syllabus into three groups..

1. Network system and Components.
2. Core System
3. Typical system

However in teaching and learning the subject, the approach is changed slightly. There are some topics which as not within the syllabus, but becomes necessary in order to understand the IMA. The topics are:
- Circuit and Packet switching.
- Ethernet
- ARINC 429 and 629

A. Circuit Switching and Packet switching, -
A video can explain the

- The following is about ethernet.
Yesterday, we did the first quiz, 1. AFDX uses the following two concepts: - virtual links - BAG - band allocation gap Write a short description on the above topics.
