Full title and description

St ARINC SPECIFICATION 828-4-2015 — ARINC 828-4:2015: "Electronic Flight Bag (EFB) Standard Interface". This specification defines a common aircraft-mounted interface, connector provisions and data/power/service definitions to support installation and operation of Electronic Flight Bags (EFBs) for both forward-fit and retrofit applications.

Abstract

ARINC 828-4:2015 specifies the electrical, mechanical and logical interface requirements for Electronic Flight Bag (EFB) installations. It standardizes connector types and pin assignments, aircraft data interface services and parameters, power and Ethernet provisions introduced in Supplement 4, and includes appendices covering example wiring, connector termination, use cases and environmental test guidance for EFB equipment.

Scope

Defines a common EFB aircraft interface covering connector form/fit, power provisioning, standardized signaling and a reference plane for interfacing EFB hardware classes to aircraft systems. The document addresses aircraft data interface services and parameters, common EFB connector pin requirements and provides multiple appendices with example wiring, mounting provisions and environmental test examples. Supplement 4 specifically adds two new connectors to provide power and Ethernet to EFB installations to reduce footprint and weight.

Key topics and requirements

• Standardized EFB connector definitions, pin assignments and cross‑wiring guidance (including alternate connector options).
• Aircraft data interface services and parameter definitions to support common EFB applications (discretes, serial buses, Ethernet, USB, video interfaces, etc.).
• Power provisioning and power-supply signaling for EFBs (including provisions introduced in Supplement 4).
• Reference plane, signaling levels, connector termination and example wire types.
• Appendices with example use cases, mounting/space provisions, environmental test examples and connector termination methods.

Typical use and users

Used by aircraft manufacturers (airframers), airlines, EFB hardware and accessory manufacturers, installation/retrofit contractors, avionics systems engineers and certification authorities. It is referenced during design and installation of cockpit EFB provisions, electrical harness design, avionics integration and for ensuring interoperability of EFB applications with aircraft systems.
