Title: Next Generation Air Transportation System
1Next Generation Air Transportation System (NGATS)
2Briefing Outline
- Background on Joint Planning and Development
Office (JPDO) - Next Generation Air Transportation System (NGATS)
Block to Block Concept - NGATS 2025 Major Attributes
3Background 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
4NGATS GOALS
Expand Capacity
Ensure our National Defense
Ensure Safety
Protect the Environment
Secure the Nation
5Transformation Strategies
- Develop Airport Infrastructure to Meet Future
Demand - Establish an Effective Security System without
limiting mobility or civil liberties - Establish and Agile Air Traffic System
- Establish a User-specific Situational Awareness
- Establish a Comprehensive Proactive Safety
Management Approach - Environmental protection that Allows Sustained
Aviation Growth - Development a System-wide Capability to Reduce
Weather Impacts - Harmonize Equipage and Operations Globally

7NGATS 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
8Global Secure Access to Net CentricInformation
- Real-time free-flow of information
- Push/pull processes to relevant NGATS communities
of interest - Meld inputs from private, commercial, govt
sources - Secured according to needs and priorities
- Common awareness of day-to-day ops, events, crises
9NGATS Airborne Web
- Broad-area broadband
- Data Voice
- Surveillance
- Responsive
- User-tailored
10The 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.
11Broad-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
12Required Total System Performance
- Multiple, differentiated service levels
- Temporal Flexibility, Responsiveness
- Contracts aligning services between users and
providers
134-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
14National Dynamic Airspace
- Airspace configuration driven by user needs,
security requirements, safety, and overall
efficiency - Reconfigurable hourly
- Single mechanism for implementing TFRs, etc.
- Temporal implementation of high density, high
demand corridors, etc
15Seamless Weather Assimilation Into Decision Loops
- NGATS Weather Information Network (NWIN)
- NWIN supports push/pull information sharing
- Seamlessly assimilated into NGATS decision
loops
16Equivalent 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
17Super density Airport Operations
- Maximize runway capacity
- Reduce runway occupancy time.
- Simultaneous operations on single runway.
18Distributed 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.
19Proactive 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
