Purpose

This document defines the aircraft industry's standards for Loadable software Parts (LSPs)and software transport media parts (Media Sets). It describes the common principles and rules to be applied to any part of a data load system, to insure compatibility and inter-operability. It includes part numbering, content, labeling and formatting of an LSP, and a Media Set containing LSPs.

Loadable Software Airplane Parts (LSAP) is a subset of the LSP class of parts. All requirements for LSPs in this document also apply to LSAPs.

Uniform software LSP and Media Set formats enable suppliers to employ common (standardized) loadable software processes, procedures, and support tools.

It is intended that software loaders, tools, processes and aircraft systems reference this standard for definition of loadable software part and software transport media content and format. This should be independent of any specific data load system, production process, or aircraft system that uses the LSP.

Applicability

This standard is applicable to all loadable software parts and software transport media intended for use in aircraft programs, systems, equipment, and Line Replaceable Units (LRUs).
