D.1.2) CMC Data

This software was written in VB5 and processed the large amount of ACARS data that arrived as plain text. In its raw form the data could not be reviewed retrospectively and was completely user-unfriendly.

Not only did the software process the information into user-friendly HTML that could be viewed by many users, it was able to show relationships between items of data.

The page below shows a post-flight fault report from an aircraft, formatted to resemble that printed on the aircraft. Reports of interest (either requested for engineering troubleshooting or known problems) were highlighted.

All such reports were store for retrieval at will.

The CMC Data report, below, shows the history of faults in the various ATA chapters and sub-chapters for the whole fleet. The frequency of reports was indicated by the intensity of the orange shading (or blue indicates no report). The 'note' icons linked to the troubleshooting procedures in the on-line documentation. 

Nominally the 'home page', this screen showed the position, track and (by colour) status of the aircraft on a map. Selecting the aircraft icons took the user to an aircraft-specific page.

Selection of the 'maps' page showed the position and track of the aircraft overlaid over open-source satellite imagery.

The page below (the only image I have) provided an overview of the maintenance status of the aircraft. This could be drilled-down into system specific information, showing - during flight or on request - the details of tyre pressures, brake temperatures, engine faults, etc.,
