Microfilm, Microfiche and Computerised Presentations

Due to the increased complexity of modern aircraft systems, the amount of information needed within the maintenance, spares and repair manuals has grown to an enormous extent. For example, the maintenance manuals for one modern aircraft alone, consist of twenty volumes, each of which would be more than 76mm (3 in) thick. To compress even greater amounts of data, other media are utilised in order to make the information more easily available to aircraft servicing technicians. These include microfilm, microfiche and computers (CD-ROM).
