Covers the characteristics of a standard firmware loader for avionic shops which can copy digital information into memory devices installed in circuit card assemblies, On-Board Replaceable Modules (OBRMs) and Line Replaceable Modules (LRMs). Also includes the recommendations of the air transport community about the development and design of firmware loader equipment.
