Software Data Loader (SDL) Subcommittee

Last Update: March 23, 2016

Co-Chairman - Rod Gates, American Airlines
Co-Chairman - Ted Patmore, Delta Air Lines

APIM 10-016B: Software Data loading Clarifications to ARINC 615-3 and ARINC 615-4 (pdf, 164K)
APIM 13-007: Standards for Shop Loading LRUs (pdf, 194K)
APIM 15-003: Supplement 4 to ARINC 665 Loadable Software Parts (pdf, 53K)

Goal: The objective is to develop standards for software data loading. This includes development of a high-speed data loader with high-density storage media. Standards for file format, media type, part numbering and terminology will be developed in a way that can be used for various data loading devices.

Scope: This subcommittee prepares documents for the interfaces between the software data loader and the target hardware. It also prepares standard formats for loadable software airplane parts so that all of the requirements of configuration management of LSAPs may be accomplished.

Benefit: The work of this subcommittee allows common tools to be used for the transfer of LSAPs from the airline to the target hardware, whether it is installed onboard the aircraft or on the test bench.

  Staff: Scott L. Smith
Reference: 13-047/ABN-41
Effective: March 15, 2013 - Indefinite

ARINC Report 665, Loadable Software Standards, Section 4.0 defines the use of Cyclic Redundancy Codes (CRC), also known as Cyclic Redundancy Checks.

ARINC Report 665-3, Section 4.2.9, CRC Examples refers to Appendix K, which provides guidance on the calculation of loadable software part CRCs. Appendix K provides an orientation to, instructions for and examples of Loadable Software CRCs and references sample files and corresponding CRCs provided in electronic code formats in this Technical Application Bulletin (TAB).
