• Based upon IEEE 802.3 Ethernet

• Network data transition standard AFDX – Avionics Full-Duplex Switched

Ethernet

Full-duplex

Redundancy

Deterministic

High speed performance

Profiled network

• High data integrity achieved

• AFDX bus is used in Airbus A380, Boeing 787, Sukhoi Superjet 100

ARINC 661 Features

ARINC 661 defines Cockpit Display System (CDS) interface for avionics

applications

Display systems interface unification

Normalization of communication between User Application and CDS

through:

• Definition file

• Kernel CDS, instantiating indication units (widgets)

• Run-time data exchange protocol

Could be used with various data transfer protocols (ARINC 664, 429)

Display Unit indicates on of the

windows, consists of layer(s)

A layer owns a number of widgets

Each widget has common parameters

(ident, position, size), as such as

special for widget type (EditBoxText)

Some widget types:

• TextBox, TextEditBox

• CheckButton, PushButton

• SelectionListButton
