1 The NextGen Vision of Future Safety Presented to: OPTICS Conference By: Maria Di Pasquantonio Date: December 17, 2014

2 Agenda Challenges for Aviation Safety Examples of NextGen Improvements / Programs NextGen Portfolios SMS Overview NextGen Human Performance & Safety Potential Future Research Areas 2

3 Challenges for Aviation Safety Societal expectations for safety One size does not fit all Increasing amounts and types of operational data Pressures: economic, security, environmental Changing workforce demographics Changes in technology and operations Where to put risk mitigation 3

4 New Technologies, Vehicles and Operations 4

5 Human System Integration Dealing with Mixed Equipage Operations in the Design and Evolution of the National Air Space Workforce Selection, Training, and Proficiency Simulator used for Visual Approach Training 5

6 National Airspace System (NAS) Systems Integration & Operations Integrating New Systems NextGen Human Machine Design, Integration, and Certification 6

7 Delivering NextGen Improvements Legacy System Radar Inefficient Routes Voice Communications Disparate Information Fragmented Weather Forecasting Weather Restricted Visibility Forensic Safety Systems Nationwide Focus NextGen Satellite Performance Based Navigation Voice & Digital Communications Automated Decision Support Tools Integrated Weather Information Improved Access in Low Visibility Prognostic Safety Systems Focus on Congested Metroplexes 7

8 Delivering NextGen Automatic Dependent Surveillance - Broadcast ADS-B ADS-B uses GPS technology to determine an aircraft s location (and other information, such as airspeed), and broadcasts that information to controllers and other equipped aircraft via a nationwide network of ground stations. ADS-B provides surveillance where radar can not be deployed, such as remote areas of Alaska and the Gulf of Mexico Benefits Provides more frequent position update-rates than radar = precise location information of aircraft Provides in-cockpit traffic and weather information Improves safety for pilots ADS-B also enables aircraft-to-aircraft surveillance. 8

9 Surveillance ASDE-X/ ADS-B Improved pilot and controller situation awareness of surface traffic, as well as surface vehicles Reduction in runway incursions due to enhanced conflict prediction alerts Allows for improved and safer low-visibility operations General aviation safety is improved by reducing the number of mid-air collisions and near collisions 9

10 Communications Data Communications Reduction of radio noise and workload is achieved with the switch to digital communications Data Comm will allow for complex clearances which are currently not operational Data Comm will reduce clearance read-backs and improve the comprehension of taxi instructions 10

11 Navigation - Delivering NextGen Performance Based Navigation (PBN) Ground-Based Navigation Performance-Based Navigation Reduced flight time and fuel Flexible weather reroutes Precision routes Integrated traffic flow End-to-end PBN network Airspace deconfliction 11

12 Terminal Flight Data Manager As-Is Inefficient traffic coordination Inefficient inter-facility coordination Surface delays and congestion To Be Shared surface situational awareness displays Interface to Flight Operator Systems Tower and airport configuration management TFMS, SWIM, FTI/LAN, AOCNET/ CDMNET, DataComm TBFM, TFMS, SWIM, FTI/LAN, ERAM, STARS, ASDE-X 12

13 NextGen Weather Operational Overview As-Is Inconsistencies across domains Unique data types, fixed time, space resolution, range, and latencies User must mentally process multiple information sources to assess the potential impact To Be Consistent weather information across domains Implementation of a common weather exchange model (i.e., WXXM) Improved aviation weather information Improve Safety 13

14 ACAS X Introduction Airborne Collision Avoidance System ACAS X An interoperable expansion of a family of aircraft collision avoidance systems developed for use in NextGen airspace Provides the same general role as TCAS II: Surveillance of nearby aircraft Coordination with other aircraft collision avoidance systems Supports New Capabilities: Leverages Additional Surveillance Sources Intended for multiple types of host aircraft Tunable for Reduced Separation Operations 14

15 NextGen Portfolios Performance-Based Navigation (PBN) Time-Based Flow Management (TBFM) Collaborative Automated Traffic Management (CATM) Improve Surface Operation (SurfOps) Improved Multiple Runway Operations (IMRO) Improved Approaches and Low Visibility Operations (IaLowVis) Separation Management (SepMgmt) On-Demand NAS Information (ODNI)) System Safety Management (SSM) Environment & Energy (E&E) 15

16 An integrated collection of principles, policies, processes, procedures, and programs used to identify, analyze, assess, manage, and monitor safety risk in the provision of air traffic management and communication, navigation, and surveillance services. 1 16
