ARINC 660B

The origin of this document is traceable to a number of industryactivities but focuses primarily on the evolving airspaceoperations to be implemented by NextGen and SESAR that appearfeasible in the next decade.

From these inputs, the AEEC set out to define impacts toavionics architectures that would apply to new and retrofitairplanes, recognizing that the impacts on the architectures wouldvary as a function of the existing avionics baseline.

The equipage impacts described in ARINC Report 660B are intendedto provide the airlines with the necessary information to evaluatemodernization proposals, and to support the overall goal of fleetcommonality while meeting operational requirements.

Note that the descriptions in ARINC Report 660B reflect avionicsarchitectures from a transport category airline perspective but mayalso have application to the regional market in some aspects. Forexample, Sections 2 (INTRODUCTION TO NEXTGEN/SESAR CONCEPTS) and 4(IMPLICATIONS FOR AIRBORNE FUNCTIONS) may be applicable to both themajor and regional segments, while Sections 3 (AVIONICS REFERENCEARCHITECTURES) and 5 (AVIONICS ARCHITECTURES TO SUPPORTNEXTGEN/SESAR) specifically speak to large transport categoryaircraft operators. Although unique military requirements are notaddressed in this document, Military Transport Aircraft mustsatisfy the same requirements as commercial transport aircraftsince most of their operations are in civil airspace.

Purpose

This document identifies and describes the aircraft avionicscapability necessary for operation in the evolving CommunicationsNavigation Surveillance/Air Traffic Management (CNS/ATM)environment expected for the FAA NextGen program, Single EuropeanSky ATM Research (SESAR) program and considerations of the JapanCollaborative Actions for Renovation of Air Traffic Systems(CARATS). These capabilities are intended to satisfy the industry’slong-term CNS/ATM operational objectives.

The International Civil Aviation Organization (ICAO) isdeveloping an Aviation System Block Upgrade (ASBU) plan toharmonize the Air Traffic Management (ATM) improvement programsacross the globe. The ASBU defines target implementation timelinesorganized in four five-year blocks: Block 0 – 2013, Block 1 – 2018,Block 2 – 2023, and Block 3 – 2028 onward. Each Block addressesfour aviation performance areas:

• Airport operations
• Globally-interoperable systems and data
• Optimum capacity and flexible flights
• Efficient flight paths

The Blocks contains Modules which define the Communication,Navigation, and Surveillance (CNS) information management functionsrequired for the aircraft and ground components. Descriptions ofthe ASBU Blocks and Modules can be found in the ICAO WorkingDocument for the Aviation System Block Upgrades, The Framework forGlobal Harmonization, Issued 28 March 2013.

ATM Modernization plans emphasize broad use of datalinkcommunication, GNSS navigation and the various surveillancecapabilities to improve flight deck situational awareness andenhance performance-based operations. This document assesses theimpact of airspace modernization plans to airborne avionicsequipment and architectures, recognizing that the benefit fromequipping aircraft may depend on coordinated changes toregulations, procedures, ground infrastructure, etc. The equipageanalyses contained herein are intended to represent a high levelsystem view that can be broadly disseminated to airlines, airspaceplanners, Air Navigation Service Providers (ANSPs), airframemanufacturers, avionics suppliers and others who participate in thedevelopment process. This document represents broad airline andindustry consensus.

This document, ARINC Report 660B, is the successor to ARINCReport 660A published in 2001. It focuses on long-term CNS/ATMobjectives. The architectures discussed in this document reflectcurrent, evolving and end-state configurations to accommodate thecurrent understanding of NextGen/SESAR plans.

The challenges to the industry set forth by this documentrequire an unprecedented degree of cooperation. The benefits thatthe airlines expect are reduced avionics acquisition costs, reducedlife cycle costs, early attainment of operational benefits,flexible software revisions, fleet commonality and system growthcapacity.
