Full title and description

St ARINC SPECIFICATION 844P1-2016 — ARINC Specification 844, Part 1: Guidance for Target Hardware Design — Airborne High Speed Data Loader (guidance mapping to ARINC Report 615-3). This document provides target (line‑replaceable unit/module) hardware implementation guidance for supporting high‑speed airborne data loaders, clarifies required features and supported subsets of ARINC Report 615-3, and defines required loadable software part formats and related interface expectations.

Abstract

ARINC Specification 844P1-2016 offers prescriptive guidance for designers of target hardware that will interact with airborne High Speed Data Loaders (HSDL). Part 1 is written specifically to align with ARINC Report 615-3, describing hardware interface requirements, supported feature subsets of ARINC 615-3, and mandates for compatible loadable software part formats (for example, ARINC Report 665 Supplement 2 or ARINC Specification 838 formatted parts). The specification is intended to enable interoperable, standardized data loading operations between loaders and targets.

Scope

This specification defines the hardware‑level requirements, interface expectations and implementation guidance for targets (LRUs/LRMs) that will be loaded using airborne high speed data loaders conforming to ARINC Report 615-3. It restricts and clarifies the supported subset of ARINC 615-3 features for target designers, specifies required formats for loadable software parts (e.g., ARINC Report 665‑2 or ARINC Specification 838 format), and provides the blueprint for interoperable data loader/target implementations across avionics platforms.

Key topics and requirements

• Mapping and clarification of ARINC Report 615-3 features that targets must support.
• Hardware interface guidance for target connectors, signalling and mechanical considerations relevant to high‑speed data loading.
• Requirements for recognition and handling of loadable software parts—mandating ARINC Report 665 Supplement 2 or ARINC Specification 838 formatted parts where applicable.
• Recommended implementation subsets and behavioral expectations to ensure interoperable loading operations with common data loader implementations.
• Guidance on partitioning, status reporting, error handling and verification during load operations.

Topics listed reflect the standard’s emphasis on interoperability between data loader manufacturers and target implementers.

Typical use and users

Primary users are avionics hardware designers and engineers who design LRUs/LRMs to be loadable by airborne high‑speed data loaders, data loader manufacturers implementing ARINC 615-3 compatibility, airline and MRO technical staff responsible for fleet data loading processes, system integrators, and certification engineers validating data loading interfaces and procedures.

Related standards

Commonly referenced and related documents include ARINC Report 615-3 (Airborne Computer High Speed Data Loader — the ARINC 615 supplement this part clarifies), ARINC Report 615-4 (related but different supplement; addressed in Part 2 of ARINC 844), ARINC Report 665 (and Supplement 2) for loadable software part formatting, and ARINC Specification 838 for formatted loadable software parts. Implementers should also consider related ARINC interface and connector standards as applicable.

FAQ

Q: What is this standard?

A: ARINC Specification 844P1-2016 is guidance for target hardware design that clarifies and prescribes how airborne high speed data loader functionality (as defined in ARINC Report 615-3) should be supported by target LRUs/LRMs to ensure interoperable data loading.

Q: What does it cover?

A: It covers hardware‑level requirements, supported subsets of ARINC 615-3 features for targets, expectations for handling loadable software parts (e.g., ARINC 665‑2 or ARINC 838 formats), connector/mechanical considerations and behavioral guidance for successful load operations.

Q: Who typically uses it?

A: Avionics LRU/LRM designers, data loader manufacturers, airline and MRO technical staff, system integrators and certification engineers involved in avionics software/hardware loading and configuration management.

Q: Is it current or superseded?

A: The document was published in 2016 and product listings indicate it is distributed as the 2016 active edition. Users should verify whether a later revision or replacement exists with ARINC/SAE‑ITC or the AEEC before relying on it for new designs or certification activities.

Q: Is it part of a series?

A: Yes — ARINC Specification 844 is published in two parts: Part 1 (844P1) aligns with ARINC Report 615-3, and Part 2 (844P2) aligns with ARINC Report 615-4. The two parts allow implementers to reference the appropriate guidance for the specific ARINC 615 supplement they intend to support.

Q: What are the key keywords?

A: ARINC 844, 844P1, ARINC 615-3, data loader, loadable software part, ARINC 665, ARINC 838, target hardware, LRU, avionics.
