## OUTLINE

- NATIONAL AIRSPACE SYSTEM (NAS)
- WHY AND WHAT IS A NAS ARCHITECTURE
- NAS ARCHITECTURE DEVELOPMENT
- VERSION 2.0 AND 4.0
- THE NAS ARCHITECTURE DATA BASE

## NATIONAL AIRSPACE SYSTEM (NAS)

## National Airspace System

## NAS Sites Are Located Throughout the United States

## Aviation Has Broad Impacts

## Traffic is Growing Along with the Economy

## WHY AND WHAT IS A NAS ARCHITECTURE

## Why do we need a NAS Architecture? 

- The NAS  Architecture is not an end-state, but a “living” representation of an integrated and evolutionary approach to NAS Modernization.
- Promotes FAA/Industry collaboration
- Supports the FAA acquisition and budget processes
- Provides decision makers with the NAS interdependency data necessary to make mission need, investment, and budget decisions
- Provides framework to develop NAS and lower level requirements
- Provides complete and consistent trace from NAS level needs and requirements to capabilities (system and non-systems) procured by IRTs/IPTs

## The NAS Is Aging

## What is NAS Architecture?

- NAS Architecture is collection of processes and their products that define the evolution of NAS for Aviation Community and FAA
- Reflects the balancing of user and service provider needs against the available resources
- Resources include R,E &D; F&E; and OPS budgets
- Prioritized by time phase
- Phase 1 (98-02), Phase 2 (03-07), Phase 3 (08-15)
- Provides Logical and Technical Views

## What is NAS Architecture?

- NAS Architecture is collection of products (and processes to develop them) that provide Logical and Technical views to Aviation Community and FAA on how to meet their needs

## NAS Architecture Views

- NAS Architecture consists of Logical and Technical Views
- Logical View provides strategic plan to obtain the desired operational services and capabilities
- Provides top level functionality and defines programmatic cost and schedule to satisfy needs
- Majority NAS architecture work to date in this area
- Technical View defines specific capabilities and their translation into NAS level requirements
- Provides basis for evaluation and implementation of NAS architecture capabilities to meet user and service provider needs using the Acquisition Management System (AMS)

## NAS ARCHITECTURE DEVELOPMENT

## Architecture Development

- The need for NAS Modernization has been substantiated by
- FAA Financial Assessment (Coopers and Lybrand)
- White House Commission on Aviation Safety and Security
- National Civil Aviation Review Commission
- The NAS Architecture is the result of a collaborative effort involving
- Intra-Agency Coordination
- Industry Collaboration
- International Coordination
- The NAS Architecture is one of three essential elements of the overall NAS Modernization Plan.  The other two are:
- Detailed Concept of Operation
- Certification Plan

## Independent Audits / Recommendations

- Coopers & Lybrand
- Validated modernization costs as being reasonable
- Suggest changes to the internal structure of the FAA
- NCARC (National Civil Aviation Review Commission)
- Rapidly growing demand and reduced capacity caused by outdated equipment
- Current FAA budget rules are crippling, forcing trade-offs
- White House Commission on Aviation Safety and Security
- Concluded that 2012 is too long a time to wait for benefits
- Recommended that the FAA develop a revised NAS modernization plan with the goal of achieving a fully modernized system by the year 2005. (Recommendation 2.1)
- Requires $5.4B F&E

## Version 2.0 and 4.0

## Alternatives Design Concept

- Alternative 1:
- Free Flight Target

- Alternative 5:
**PROPOSED V2.0**

- Alternative 2:
- Aggressive Transition

- Alternative 4:
- Sustain Performance

**NOT TO SCALE**

- Alternative 3:
- Free Flight Modified

- Alternative 0:
- Sustain

- Proposed V 2.0 Architecture (1996)

**Notes:**
This chart shows the relative position of the architecture alternatives we explored.  It is not to scale but does provide a visual feel for the scope of the alternatives.  You’ll notice that none is within the confines of the OMB budget pass back.
Alternative 2, the Aggressive Transition architecture, is perceived to provide better benefits to the users and the FAA but places demands on everyone that have been found to be politically untenable.  It requires mandating of equipage to all using the airspace and incorporates relatively short periods for all to equip with new avionics.  It probably exceeds the FAA’s and Industry’s ability to procure, deploy and to certify,   but it provided us a mechanism to answer some what if questions we have been asked. 

## NAS Architecture Version 4.0

- Describes the new capabilities called for in the Joint Government/Industry Concept of Operations
- NAS-Wide Information Sharing, Satellite-Based Navigation and Landing, Improved Surface Movement Detection, Improved Arrival and Sequencing, etc.
- Provides Balanced approach for:
- Sustaining NAS Infrastructure
- Providing NAS Services at new locations
- Implementing New Capabilities into the NAS
- Describes the sustainment of existing infrastructure
- NAS Facilities, Ground-Based Navigation/Landing Aids, HOST Replacement, Voice Radios, Power generators, Administrative systems, etc.
- Does not transfer any cost to the user
- Version 2.0 transferred $10B over 20 years
- Achieves acceleration of New Capabilities
- Free Flight Phase 1
- Provides methods to prioritize capabilities and services that can be provided by the FAA within available resources

## Key Points of NAS Architecture V4.0

- Accommodating aviation’s growth and replacing aging equipment/infrastructure
- Collaboration with aviation community
- Providing an advanced, integrated, and safe aviation system
- Improving quality and reliability through integrated digital communications
- Using satellite-based services for exceptional accuracy, increased operational safety, and expanded airport coverage
- Timely and accurate weather data for controllers and pilots
- Deploying advanced automation capabilities to accelerate user benefits and assess modernization risks
- Sharing information to more effectively manage flight planning with common view of traffic flow
- Optimizing aircraft sequence with improved controller tools
- Building upon capabilities with seamless transitions
