NextGen Explained

Progress in Modernizing the NAS

§ Most of the foundational infrastructure to modernize the National Airspace System (NAS) is complete including:

• Traffic Flow Management System
• Time Based Flow Management
• En Route Automation Modernization (ERAM).

§ Enablers of NextGen

• ERAM and STARS are not NextGen systems but they enable

critical NextGen capabilities at all phases of flight.

• Terminal Flight Data Manager is in development and

expected to be operational at 89 sites starting in 2020.

6

Progress in Modernizing the NAS

§ On top of that foundation,

• ADS-B and SWIM are available nationwide
• Phase 1 of DataComm became operational at 55 airports in 2016

and is expanding to seven more sites in 2019

• More than 9,000 PBN routes and procedures are available across

the country and new ones are introduced regularly

• PBN work has been completed at four metroplex locations and

efforts continue at seven other sites

• NextGen Weather Processor and Common Support Services–

Weather are scheduled to be operational nationwide in 2022

• Improved multiple runway operations benefit dozens of airports,

and improved low-visibility operations are available to operators nationwide

7

TRIVIA Break Per recent news from Flight Aware, what percentage of 17,000 turbine powered aircraft are currently equipped with ADS-B Out?

Benefits of NextGen

Benefits of NextGen

At a Glance § Nearly 4,000 Wide Area Augmentation System (WAAS) localizer performance with vertical (LPV) guidance approach procedures serve close to 2,000 airports.

• More than 1,000 of those airports do not have an instrument landing system (ILS).

§ More than 90,000 general aviation aircraft are equipped to fly WAAS- enabled procedures. § Satellite-enabled approach procedures provide instrument-rated pilots access to more airports during low visibility compared to using an ILS. § These procedures are enabling the FAA to retire many legacy ground- based navigation aids.

10

CNS Benefits of NextGen

Communications – CPDLC text based messaging will enable faster and more accurate delivery of instructions Navigation – Space based navigation with WAAS GPS is enabling more efficient routes in all phases

• f flight

Surveillance – ADS-B technology enabled the FAA to grow it’s surveillance foot print and add situational awareness features like traffic and weather

11

What is PBN

PBN takes advantage of GPS satellites and cutting-edge aircraft navigation equipment to create new pathways in the sky. This allows aircraft to fly shorter, more-efficient routes to their destinations while aircraft burn less fuel. PBN in the National Airspace System (NAS) mainly consists

• f:
• Area navigation (RNAV) standard instrument

departures (SID)

• Q- and T-Routes
• RNAV Standard Terminal Arrivals (STAR)
• Required navigation performance (RNP) approaches
• RNP approaches with authorization required (AR)
• RNP approaches with LPV

12

WAAS LPV Approaches

13

TRIVIA Break How many FAA owned and operated VORs are maintained in the National Airspace System currently?

14

Transitioning to a PBN-Centric NAS

How does the FAA continue to support both the legacy and PBN procedures moving forward?

• The FAA must currently maintain all legacy

and PBN procedures/routes/infrastructure

• Much of the legacy infrastructure is difficult to

maintain as parts are no longer manufactured

• r available

Moving Forward…

• A successful transition to a PBN-centric NAS

will require a sustained, long-term focus on collaboration across aircraft operators, manufacturers, airport operators and the communities that surround airports

• FAA’s PBN NAS NAV Strategy

VOR Minimal Operating Network (MON)

§ The FAA's VOR Minimum Operational Network (MON) implementation program will transition from a legacy network of more than 950 VORs to a MON of about 650 VORs by 2025. § In July 2016, the FAA published a list in the Federal Register of VOR sites that may be shut down. § NDBs are also being decommissioned as LPV and LP procedures provide lower minimums than are available with NDB approaches

Welcome to 2019 and Beyond..

21

Lots of Competing Interests for Access

22

Challenges in an ever-evolving NAS?

§ NextGen

• Transitioning the NAS from conventional

infrastructure/procedures to PBN

• ADS-B mandate – Jan 1, 2020
• Datacomm rollout has presented challenges
• Training always being refined and needed

§ Maintaining Airspace Access:

• New and Expanding Technologies: Commercial

space/UAS/Balloons

• Requires Segregation vs integration to manage

risks

§ GPS Interference

• Greater number of occurrences in a PBN centric

NAS where ground based backup options are limited

23

Maintaining Airspace Access

§ Integration vs segregation

• Managing Risk and acquiring data to support the safety case

§ Prioritization and Access

• Large TFRs and restrictions impacting civil and commercial operations
• Need to ensure fair and balanced access/prioritization

§ Impacts to existing airports/infrastructure

• Spaceports near existing airports
• UAS operations in vicinity of airports – recent ops at EWR
• Balloons at altitudes impacting airways and ingress/egress into airports

§ Need for situational awareness/training of operators not familiar with airspace structure/rules

24

Commercial Space Taking Off

25

UAS Moves Toward Integration

§ 1,000,000+ drones registered § Part 107 § UAS Integration Pilot Program § FAA’s UAS Data Exchange – Low Altitude Authorization and Notification Capability (LAANC) § UAS test sites § Drone Advisory Committee § UAS Safety Team § NASA’s Unmanned Traffic Management concept

B4UFLY App

26

What about GPS Interference

§ Planned GPS interference events happen routinely across the NAS § Possibility of impacts to navigation and secondary control systems § Number of intended jamming events continues to grow § Many operational reports of issues during planned outages § Don’t forget to check NOTAMs § Report issues to ATC

FLIGHT ADVISORY GPS INTERFERENCE TESTING

27

Summary

§ The NAS will continue to evolve and change § There is no “light switch” approach § Transition often brings challenges § Those challenges also present OPPORTUNITIES

28

TRIVIA Break When is the VOR MON to be complete?
