• Next Generation Air Transportation System (NGATS) Block to Block Concept

• NGATS 2025 Major Attributes

Briefing Outline


Background on Joint Planning and Development Office (JPDO)

Vision 100: The Century of Aviation Reauthorization Act– Tasked the Secretary of Transportation to establish

the Next Generation Air Transportation System (NGATS) Joint Planning and Development Office (JPDO) within FAA

– Tasked as cooperative effort across DOT, DoD, NASA, Commerce, DHS, and the White House Office of Science and Technology

– The law required JPDO to submit to Congress a proposed NGATS plan in December 2004


NGATS GOALS

Expand Capacity

Ensure Safety

Protect the Environment

Ensure our National Defense

Secure the Nation


Transformation Strategies

1. Develop Airport Infrastructure to Meet Future Demand

2. Establish an Effective Security System without limiting mobility or civil liberties

3. Establish and Agile Air Traffic System4. Establish a User-specific Situational

Awareness 5. Establish a Comprehensive Proactive

Safety Management Approach6. Environmental protection that Allows

Sustained Aviation Growth7. Development a System-wide Capability

to Reduce Weather Impacts8. Harmonize Equipage and Operations

NGATS 2025 Major Attributes

•Global Secure Access to Net CentricInformation

•NGATS Airborne Web•Broad-Area Precision Navigation•Required Total System Performance•4-D Trajectory Management•National Dynamic Airspace •Seamless Weather Assimilation Into Decision Loops

Net Centric data/info sharing including “Air Net” Communications•Equivalent Visual Operations •Super density Airport Operations•Distributed Airport Operations•Proactive Risk Based Safety Management


Global Secure Access to Net Centric

Information

•Real-time free-flow of information

•Push/pull processes to relevant NGATS communities of interest

•Meld inputs from private, commercial, & gov’t sources

•Secured according to needs and priorities

•Common awareness of day-to-day ops, events, crises


NGATS Airborne Web

•Broad-area broadband

•Data & Voice

•Surveillance

•Responsive

•User-tailored


The Evaluator

•All users “post” desired 4D trajectories in common system that continuously evaluates all trajectories for mutual compatibility.

•Integrates all information: weather, security, defense, etc.

•Management by trajectory allocates functions between automation and humans and aircraft operators and “central” service providers.


Broad-Area Precision Navigation

• Navigation precision sufficient to enable precision approaches CAT I/II/III

• Broad Area to Global Availability of Nav Services

• Divests current ground-based systems of landing/navigation aids

• Reduction/elimination of runway lighting, markings


Required Total System Performance

• Multiple, differentiated service levels

• Temporal Flexibility, Responsiveness

• “Contracts” aligning services between users and providers


4-D Trajectory Management

• Users have 4D trajectories which are basis for planning and execution over multiple time horizons.

• 4D trajectories exchanged among users and ATM service provider using “airborne web”

• Separation assurance/management performed using current aircraft states and intent as defined by “active” 4D trajectory

• Strategic Traffic Management performed using 4D trajectories that include probabilistic information

• Where appropriate, “4D contracts” exist between users and

ATM service providers


National Dynamic Airspace

•Airspace configuration driven by user needs, security requirements, safety, and overall efficiency

•Reconfigurable hourly

•Single mechanism for implementing TFR’s, etc.

•Temporal implementation of high density, high demand corridors, etc


Seamless Weather Assimilation Into Decision Loops

•NGATS Weather Information Network (NWIN)

•NWIN supports push/pull information sharing

•Seamlessly assimilated into NGATS “decision loops”


Equivalent Visual Operations

•Enable aircraft perform “equivalent visual” operations in non-visual conditions

•ATM providers delegate “maintain separation” responsibility to aircraft operators

•System-wide availability at all “air portals”


Super density Airport Operations

•Maximize runway capacity

•Reduce runway occupancy time.

•Simultaneous operations on single runway.


Distributed Airport Operations

•Employ airborne separation assurance and cost-effective sequencing automation at non-towered, non-radar airports.

•Affordable capabilities and procedures that enable low visibility

landings and low-visibility taxiing.


Proactive Safety Management

•Multi-Agency National Strategic Plan for Safety

•National Safety Management System Criteria

•Proactive Risk Based Safety Management – Prognostic Approach

to Safety

•Focus on Reduction of Fatality Risk

•National Safety Culture
