Air Canada Saves with Aircraft Maintenance Scheduling

The planning of aircraft maintenance by Air Canada had become increasingly difficult in the early 1970's. It sometimes required several weeks for planning personnel to manually develop an acceptable aircraft schedule. The lack of an accurate and timely maintenance scheduling tool led to the development of the Aircraft Maintenance Operations Simulation (AMOS) model. Two years after its introduction, Air Canada has so improved the flying hours achieved between maintenance checks that a 5% reduction in the labour and material costs associated with the maintenance of aircraft has resulted. A letter of verification of this reduction may be found at the end of this article.
