Briefing Outline

• Background on Joint Planning and Development
  Office (JPDO)
• Next Generation Air Transportation System (NGATS)
  Block to Block Concept
• NGATS 2025 Major Attributes

3
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 our National Defense
Ensure Safety
Protect the Environment
Secure the Nation
5
Transformation 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

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

8
Global 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

9
NGATS Airborne Web

• Broad-area broadband
• Data Voice
• Surveillance
• Responsive
• User-tailored

10
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.

11
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

12
Required Total System Performance

• Multiple, differentiated service levels
• Temporal Flexibility, Responsiveness
• Contracts aligning services between users and
  providers

13
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

14
National 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

15
Seamless Weather Assimilation Into Decision Loops

• NGATS Weather Information Network (NWIN)
• NWIN supports push/pull information sharing
• Seamlessly assimilated into NGATS decision
  loops

16
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

17
Super density Airport Operations

• Maximize runway capacity
• Reduce runway occupancy time.
• Simultaneous operations on single runway.

18
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.

19
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
