Purpose

his document defines the aircraft industry's standards for Loadable Software Parts (LSPs) and Media Set Parts (MSPs). It describes the common principles and rules to be applied to any part of a data load system to ensure compatibility and interoperability. It includes part numbering, content, labeling, and formatting of an LSP, and a Media Set containing LSPs.

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

Uniform software LSP and MSP 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 definitions of LSP and MSP content and format.
