Key Capabilities - Network Enabled Access
 Network Enabled Operations (NEO)
 Network Enabled Infrastructure (NEI)
 Network Enabled Weather (NEW)
9
Key Capabilities – Performance-Based Operations and
Services
 Weather Impacted Ops.  Dynamic Resource & Aerospace Management
 Modernized Surface Ops.  Trajectory-based Separation Management
 Collaborative ATM  Trajectory-based Ops.
10
Key Capabilities - Weather Assimilated into Decision-
Making
 Net-centric weather information is made available and understandable to all approved users.
 A reliable virtual, common weather picture is foundational for optimal air transportation
decision-making.
 Presentation of weather data is tailored to user operational needs.
 Widespread use of integrated probabilistic weather-related decision support systems
 Automatic updates to users based on operational need
 An adaptive observing system integrating ground, airborne, and
spaced based sensors
11
Key Capabilities – Layered Adaptive Security
 Adaptive Security for People, Cargo, Airports and Aircraft
 Risk Assessment-Driven Evaluation and Response
 Positive Identification for People and Cargo
 Preventive Threat Detection and Mitigation
12
Key Capabilities – Position, Navigation and Timing Services
(PNT)
 Air routes are independent of the location of ground-based navigation aids.
 RNAV is used everywhere; RNP is used where required to achieve system objectives, which
reduces controller workload and increases efficient use of NAS resources (airspace and
runways).
 System performance meets operational needs to service the demand.
 Increased availability of guided approaches at smaller airports (mostly) for
general aviation with lower minimums
13
Key Capabilities - Aircraft Trajectory-Based Operations
Services and Operations based on precise trajectory execution
 Self-Separation Services
 Flow Corridors
 Super Density Arrival/Departure Airspace
14
Key Capabilities - Super Density Operations
 Use of RNP operations and procedures that eliminate requirements for visual operations
 Mitigation of wake vortex constraints through detection and real-time adaptation of separations
 Improved runway incursion prevention algorithms to increase efficiency and safety
 Automatic distribution of runway braking action reports
 Distribution of taxi instructions before landing that can be automatically executed without waiting
for a separate clearance
 Use of aircraft sensors to more quickly identify the need for de-icing
operations, increasing efficiency of surface movements.
15
ATM – Goals and Objectives
 Meet both a diverse operational objectives and aircraft
capabilities and characteristics
 Meet users needs for access, efficiency, and predictability.
 Provide safe, secure, of sufficient capacity,
environmental acceptable and affordable for all users
ATM is the dynamic, integrated
management of air traffic and
airspace—safely, economically,
and efficiently—through the costeffective
provision of facilities and
seamless services in collaboration
with all parties.
16
Airports – Goals and Objectives
Airports are the nexus for many NextGen
transformational elements:
 Operational services support integrated management of
aircraft and ground support equipment on the ramp
during all weather operations
 Technology enables improved access and efficient
utilization of common use airport infrastructure
 Mission support services enable preservation of critical
airports, efficient development of airport and regional
systems, and NextGen enabled design standards
17
Net-Centric Infrastructure Services – Goals and Objectives
The concept of net-centricity ensures a
robust, globally interconnected
network in which information is shared
in a timely and consistent way among
users, applications, and platforms
during all phases of aviation
transportation efforts.
 Supports air navigation service, airport, and flight
operations
 Enables shared situational awareness
 Supports compliance and regulation oversight
 Supports security, safety, environmental, and
performance management services

Shared Situational Awareness – Goals and Objectives

Homeland Defense
Need to get a higher
resolution image from SSA
Access can be accomplished in an
automated and virtual fashion where
a standing request for information by
subscribers is produced, using
established protocols and standards.
 Shared Situation Awareness
- Real-time free-flow of info from private,
commercial, & government sources, integrated
internationally
- Push/pull processes, secured according to
needs and priorities
- Common awareness of day-to-day ops, events,
crises
 Aircraft are integral “nodes” in network
 Integrated surveillance system across
agencies and borders
19
Layered Adaptive Security Services – Goals and Objectives
To maintain effective security management
across major stakeholders, a collaborative
framework is composed of the following
key functions and processes:
 National Aviation Security
Policy
 Aviation Security Stakeholder
Involvement
 Aviation Integrate Risk
Management (IRM)
 Aviation Security Implementation
 Aviation Security Assurance
20
Safety – Goals and Objectives
The key to success is the
implementation of safety management
systems integrated at the national level.
The integrated safety management
approach being developed includes:
 a national aviation safety strategy,
 a safety improvement culture,
 a prognostic safety risk management (SRM)
capability,
 a robust and protected safety information sharing
and analysis procedure, and
 an enhanced safety assurance function.
21
Environment – Goals and Objectives
NextGen Environmental
objectives include providing
a framework to enable
environmental protection
that allows for sustained
aviation growth:
 Reduce significant noise and aircraft engine emissions in
absolute terms
 Proactively address emerging environmental issues (e.g.
water quality, energy intensity, and global climate change)
 Enable Environmental Management Systems (EMS)
capabilities system wide
22
Global Harmonization – Goals and Objectives
A key step toward gaining global
endorsement of the NGATS is to be sure
every technology, policy, and procedural
option or “element” is compatible with
existing global requirements:
 Harmonized systems, procedures for “borderless”
interoperability
 Partnerships to promote common solutions for
common problems
 Early, continuing participation in developing global
standards, procedures to ensure satisfaction of US
requirements
 Promote US position and preferred standards
globally
23
Upcoming JPDO Additions – Aircraft/Avionics – Goals and
Objectives
NextGen Aircraft objectives
would likely include developing
a framework to integrate
transformational technologies
and capabilities for airframes,
engines, and equipage:
 Airframe Technologies
 Engine Performance
 Equipage Improvements
24
