Abstract

For a maintainer, display of avionics faults on a Remote Terminal (RT)/ Maintenance Access Terminal (MAT) is essential for troubleshooting and isolation of fault. Currently the display of faults lacks intuitiveness. The display presents the detected faults without considering inter-dependency of faults, common troubleshooting steps, faults at each location and the order in which the faults need to be resolved. The proposed solution presents an integrated display which assists the maintainer by providing an intuitive representation of faults information. This type of representation of the fault information aids the maintainer in performing the maintenance in an efficient manner by eliminating duplication of effort and redundant steps.

ABSTRACT

For a maintainer, display of avionics faults on a Remote Terminal (RT)/ Maintenance

Access Terminal (MAT) is essential for troubleshooting and isolation of fault. Currently

the display of faults lacks intuitiveness. The display presents the detected faults

without considering inter-dependency of faults, common troubleshooting steps, faults

at each location and the order in which the faults need to be resolved. The proposed

solution presents an integrated display which assists the maintainer by providing an

intuitive representation of faults information. This type of representation of the fault

information aids the maintainer in performing the maintenance in an efficient manner

by eliminating duplication of effort and redundant steps.

1. Introduction

Conventionally, the aircraft maintenance is performed by maintenance technicians

(hereafter referred to as maintainers) using ground based desktop applications such as

a Remote Terminal (RT)/ Maintenance Access Terminal (MAT). The RT/ MAT is used by

the maintainer to communicate with an on board Central Maintenance Computer (CMC)

using command response protocol. The RT/MAT provides an electronic display with

information of avionics faults. The RT/MAT displays troubleshooting procedures for the

detected avionics faults and aids in executing diagnostic tests. Status of various

components and their configuration details are provided on the display of the RT/MAT.

The RT/MAT allows the maintainer to view faults and receive the troubleshooting

information from Aircraft Maintenance Manual (AMM) and Fault Isolation Manual (FIM).

However, the current representation of fault related information on the RT/MAT has

2

several drawbacks. The faults displayed by the conventional RT/MAT are not rendered in

the order in which they are to be resolved. The maintainer needs to troubleshoot each

individual fault based on the priority of faults available in the FIM. The fault data is not

considered based on location of faults or common troubleshooting steps used for

resolving the fault. This leads to duplication of effort on part of the maintainer. For

example, the maintainer performs the same troubleshooting steps for various faults even

when the same troubleshooting step has already been performed. Further, he needs to

access locations frequently as the faults are not displayed location wise. Hence, the fault

data displayed on the RT/MAT does not consider relationships between fault codes,

location of faults and faults across ATA chapter, leading to a cumbersome and time

consuming maintenance procedure for the maintainer.

2. Proposed Solution of the problem

The proposed solution provides an intuitive display of aircraft diagnostics information

during maintenance. An integrated display operable with existing RT/MAT is used for

representing active and histo...
