Using the Boeing-developed Portable Maintenance Aid (PMA) software, maintenance personnel at an airplane gate can quickly pinpoint technical problems instead of searching through thousands of pages of manuals that are usually located a considerable distance from the airplane. The PMA consists of key maintenance information contained in just a few compact disks that can be loaded into a laptop computer. The newest version of the PMA allows airlines to customize information in the software and provides enhanced search, navigation and networking capabilities.
