Hearing on
Air Traffic Control Modernization
TABLE OF CONTENTS(Click on Section)
The purpose of this hearing is to
review progress and challenges facing the Federal Aviation Administration and
the Joint Program Development Office (JPDO) in modernizing the National
Airspace System (NAS) to meet projected increases in traffic volumes, enhance
the system’s margin of safety, and increase the efficiency of the air traffic
control (ATC) system, the principal component of the NAS.
NAS Modernization: Historical Overview
The mission of
the Federal Aviation Administration (FAA) is to provide the safest, most
efficient aerospace system in the world.
To fulfill its mission, FAA must rely on an extensive use of technology,
including many software-intensive systems.
FAA constantly relies on the adequacy and reliability of the nation’s
ATC system, which includes a vast network of radars, automated data processing,
navigation equipment, and ATC facilities (airport towers, terminal radar
approach control facilities (TRACONs), and en route centers)[1]. Through
this system, FAA provides services such as controlling takeoffs and landings,
as well as managing the flow of commercial, military and general aviation
traffic between airports.
FAA operates the largest and safest air traffic control system in
the world. In fact, the FAA’s air
traffic system handles almost half the world’s air traffic activity and the
Although FAA
has successfully fulfilled its mandate to operate a safe air traffic control
system, its operating and capital expenses have grown. In contrast with the airline industry, which
has been focusing on cost cutting and efficiency over the last several years,
the General Accountability Office (GAO) found that during the period fiscal
years 1996 through 2004, FAA’s Air Traffic Services operating expenses
experienced real growth of $1.8 billion, or 43 percent. Most of this growth was due to increases in
the costs of personnel compensation and benefits. Air Traffic Services operating expenses are
expected to continue to grow through fiscal year 2010. FAA projects that expenses will significantly
outpace available funding during this period, resulting in a cumulative
operating budget deficit of nearly $4 billion.
While over the last 25
years FAA has developed some new technological capabilities, the U.S. air
traffic management system is not much different from that used in the 1960s;
the system it is still fundamentally based on radar tracking and ground-based
infrastructure. Further, FAA has faced
serious challenges meeting cost and schedule targets for several of its major, highly
complex air traffic technology acquisitions.
The NAS modernization
effort, launched during the Reagan Administration in 1981, was intended to be
completed by 1996 at a cost of $2.5 billion.
As a result of more than two decades of cost growth, schedule delays and
performance problems, FAA has spent $43.5 billion to date for its NAS
modernization effort, and plans to spend an additional $9.6 billion through
fiscal year 2009, primarily to upgrade and replace ATC systems and facilities. Major reasons that have been cited for cost
overruns and schedule slips include:
·
Inadequate program funding – In April 2005, DOT Undersecretary for Policy Jeff
Shane stated in testimony before the Aviation Subcommittee that 50 percent of
cost overruns can be attributed to a lack of stability, predictability and
availability of finances for capital investment.
·
Growth in system requirements often results from poorly defined requirements prior
to development and/or Unplanned work
that often results from misjudging the ability of commercial-off-the-shelf
(COTS)[3] or non-developmental items
(NDI)[4] to meet the FAA’s needs.
·
Stakeholders were not sufficiently involved in design
and development – Insufficient
involvement of relevant stakeholders, such as air traffic controllers and
maintenance technicians, throughout the development and approval process for
system acquisition can lead to costly changes in requirements and unplanned
work late in the development process.
·
The complexity of software development was
underestimated.
Despite the challenges FAA has had with major ATC modernization acquisitions, the GAO found that FAA Administrator Marion Blakey and FAA Air Traffic Organization (ATO) Chief Operating Officer Russ Chew have made progress in meeting cost, schedule and performance targets. See pp. 9-13.
The need for ATC
modernization is overwhelming. FAA’s
recent forecast conference could not have made it any clearer – air transportation
demand is coming that will be greater than today’s system can handle. By 2015, domestic passenger traffic will
nearly double to 1 billion passengers annually.
If the demand for air transportation continues to outpace the Federal
government’s ability to increase capacity, consumers stand to lose $30 billion
annually by 2025 due to people and products not reaching their destinations
within the time periods we expect today.
The
Future: Next Generation Air Traffic Control System
Vision 100, The Century of Aviation
Reauthorization Act of 2003, directed the FAA to develop a comprehensive plan
for a Next Generation Air Traffic Control System (NGATS) that will accommodate
dramatic growth in airline passenger travel, as well as the introduction of
unmanned aerial systems, very light jets,[5] manned commercial space launches,
hypersonic transport aircraft, and vertical takeoff and landing vehicles.
NGATS will move much of the air traffic control infrastructure from
Earth to sky by replacing antiquated, costly ground infrastructure with
orbiting satellites, on-board automation and data-link communications. NGATS will use advanced computers, precision
plotting through GPSs and computer-based decision assistance programs.
The Joint Planning
and Development Office (JPDO), created within the FAA, is leading an
inter-agency effort to leverage expertise and resources within the Departments
of Transportation, Defense, Commerce, and Homeland Security, as well as at NASA
and the White House Office of Science and Technology Policy. It has begun to develop a unified approach to
completely transform the NAS by 2025.
Building the NGATS
by 2025 will not occur in a “big bang”, but rather in an evolutionary manner
due to the fact that the current ATC system must continue operating around the
clock and wholesale replacement would be impossibly expensive. Moreover, JPDO officials indicated that a
phased, incremental approach to development and implementation is preferable
for both managing risk and controlling vendors on technologically complex ATC
acquisitions.
In light of the forecasted growth in
air travel over the next decade, the DOT Inspector General (IG) and some
stakeholders maintain that the JPDO needs to focus on modernization programs
that can be completed much sooner than the 2025 timeframe.
The primary hurdles to building the
NGATS sooner than 2025 is lack of coordination between the government and
industry, a lack of intergovernmental coordination – particularly between the
JPDO and FAA, and insufficient funding support for NGATS-specific programs. The key NGATS technologies, discussed on pp. 6-7,
are available.[6]
JPDO’s
Budget and Management Structure
The JPDO’s budget is
$36 million in FY 2006, up from $10 million in FY 2005 (about $18 million comes
from the FAA and $18 million from NASA).
JPDO brings together a staff of about 75 civil servants with contract
support from MITRE Corp., under the direction of acting director Robert
Pearce. A senior policy committee,
chaired by DOT Secretary Norm Mineta, oversees JPDO activities.
Most of the
long-term, NGATS-related research is conducted by NASA. NASA has requested $724 million for FY 2007
on aeronautical research and development (R&D), of which approximately $100
million is directed toward NGATS-related research (e.g., automated
aircraft metering and sequencing, and dynamic airspace reconfiguration). Of the $130 million requested by the FAA for
FY 2007 research, engineering and development (R,E&D), almost 70 percent,
or $88 million, focuses on improving safety – not new air traffic management
initiatives.
FAA’s capital
account – or the Facilities & Equipment (F&E) account – is the
principal vehicle for modernizing the NAS.
For FY 2007, FAA is requesting $2.5 billion for the F&E account,
which is $50 million less than last year’s appropriation, and $600 million less
than the level authorized by VISION 100 for FY 2007. Significantly, most F&E funds are
targeted at sustaining the existing ATC system, not at NGATS-specific programs. Moreover, the DOT IG is projecting a F&E
funding shortfall of between $500 million - $1.2 billion between FY 2008 and FY
2012 – before any F&E funds are spent on NGATS capital investments.
To bridge a gap
between government and the private sector, FAA established the NGATS Institute
in June 2005. The NGATS Institute is
part of the
JPDO and the NGATS
Institute come together in eight integrated product teams (IPTs) that are
addressing the architecture, polities and technological needs for airport
infrastructure, safety, security, air traffic management, weather forecasting
and environmental protection.
The law requires the
JPDO to coordinate and oversee research that could play a role in NGATS. Key to the JPDO’s mission - and making it an
effective multi-agency vehicle – is alignment of agency resources. This is a complex task, and the law provides
no authority for the JPDO to redirect agency resources.
The relationship between the JPDO
and FAA’s ATO is particularly important.
The JPDO’s planning must build upon the ATO’s existing modernization
program, and the ATO’s near-term planning horizon must be aligned with the
JPDO’s longer-term mission to transform the NAS. Moreover, the implementation of the air
traffic component of the NGATS plan will be financed primarily by the FAA’s
capital budget, and the JPDO will clearly need to draw upon the FAA’s expertise
to support its mission.
JPDO’s former director
served concurrently as the ATO’s vice president for operations planning, which
some believed facilitated coordination between the two organizations. However, FAA now plans to establish separate
positions for the JPDO director and ATO vice president for operations
planning. GAO reported that a memorandum
of understanding (MOU) that would define partner agency relationships was being
developed as of August 2005, but has not yet been completed. No matter how the relationship between JPDO
and FAA is formally structured in the future, JPDO will need the authority to leverage
key human and financial resources within the FAA.
While many industry
stakeholders are supportive and appreciative of the JPDO’s efforts to date,
particularly with respect to outlining a vision for NGATS, there is a consensus
emerging that changes in the JPDO’s management structure need to be made in
order to transition successfully from the planning stage to the program
implementation stage. Suggested changes
include, but are not limited to:
·
fast-tracking
the planning and implementation of key NGATS programs in light of the
forecasted growth in domestic passenger traffic over the next decade;
·
establishing a
JPDO program office within the FAA with authority to redirect agency resources
to NGATS programs;
·
designating the
FAA deputy administrator or ATO chief operating officer as director of JPDO to
bridge the gap between the ATO’s near-term ATC modernization efforts and the
JPDO’s longer-term mission to transform the NAS;
·
reducing the
number of IPTs in a manner that would encourage more cross-functional,
multi-disciplinary work;
·
establishing contracted
relationships with industry as opposed to the current voluntary relationships
(along the lines of the European Commission’s SESAR initiative, discussed on p.
8);
·
augmenting NGATS
planning with a well-designed set of development and implementation projects
like the recent automatic dependent surveillance-broadcast (ADS-B)
demonstrations in Alaska and the Ohio River Valley; and
·
committed funding
for NGATS.
Last July, the DOT
IG undertook an audit at the request of the House Aviation Subcommittee on the
JPDO’s progress in coordinating research conducted by other federal agencies,
identifying key NGATS technologies, and developing cost estimates.
The
NGATS Vision
Early this summer,
the JPDO will release more detailed blueprints of the operations and systems
architecture for NGATS. JPDO will seek
comment from the six federal agencies involved, the Office of Management and
Budget (OMB), and a variety of stakeholders.
Once the blueprints are vetted by these groups later this year or in
2007, they will guide the direction of near-term NGATS research and development
initiatives and early implementation efforts.
While final decisions have not yet
been made, NGATS will likely incorporate the following basic technology areas:
Automatic Dependent Surveillance-Broadcast (ADS-B)
– ADS-B is an air-to-air, air-to-ground communications, navigation, and
surveillance technology that relies on signals from the Global Position System
(GPS), 24 satellites orbiting the Earth, to broadcast the positions of properly
equipped aircraft and surface vehicles. NAS-wide deployment of ADS-B is a central component
of NGATS.
Aircraft equipped with ADS-B will broadcast their GPS position,
air speed, altitude, and planned course changes to other aircraft and
ground-based receivers. The information
of each aircraft will be displayed to pilots and controllers, providing a complete
picture of area traffic.
In
prior budgets, ADS-B was funded under the Safe
Flight 21 initiative, which demonstrated the potential of ADS-B and cockpit
displays in
For
FY 2007, FAA is requesting $80 million for the first phase of ADS-B, which will
cost a total of $600 million (half to be paid by the federal government and
half by users of the NAS) between 2007 and 2010. In May, FAA announced that it plans to
install 400 ADS-B ground stations in “targeted areas” (including the
ADS-B
is a key element in other FAA programs, including the ASDE-X program (see
p. 10), to help prevent accidents on runways. In addition to safety, capacity and
efficiency benefits, ADS-B also could be used as a security tool. Since ADS-B can present aircraft position
updates much faster than ground radar, which operates at five- to six-second
update intervals, air traffic controllers could detect more quickly an
aircraft’s departure from, say, its approach path to a runway at Reagan National
Airport.
The
major hurdles to NAS-wide deployment of ADS-B implementation are aircraft equipage
costs, and the development of technical and performance standards. Aircraft and avionics manufacturers estimate
that it could cost between $200,000 and $500,000 to retrofit commercial
aircraft with the necessary avionics. Avionics manufacturers estimate that it could
take 2-3 years to work out technical and performance standards, and another 5-7
years to complete the manufacturing and certification processes for the
required avionics.
The
Air Transport Association (ATA) and key general aviation groups support a
transition to an ADS-B surveillance system, but recognize that a number of
challenges must be addressed, including international interoperability,
equipage costs, and other technical issues.
The Airline Owners and Pilots Association (AOPA) does not oppose ADS-B,
but wants to see avionics delivered for less than $8,000 per general aviation
aircraft.
System Wide Information Management
Program (SWIM) – SWIM is a new
network information architecture that will allow airspace users to access a
wide range of information on the status of the NAS and weather conditions
securely and seamlessly. SWIM will allow
disparate ATC systems designed prior to the NGATS to exchange information using
highly specialized software upgrades.
For example, the operator of a Common ARTS console will be able to see
information sent from a STARS console, and vice versa, using SWIM. FAA is requesting $24 million for this
program in FY 2007.
The Cost of
NGATS
A major challenge
faced by the JPDO is that its attempts to implement the NGATS coincide with
declining trust fund balances, budget cuts and shrinking capital investments
dollars. Key NGATS programs, including
ADS-B and SWIM, are included in the FAA’s FY 2007-2011 NAS Capital Investment
Plan.
DOT, FAA and JPDO
have not provided a detailed cost estimate and implementation schedule for
NGATS due primarily to the fact that the NGATS operating requirements and
architecture have not been finalized. However,
the FAA’s Air Traffic Organization (ATO) released a preliminary cost estimate
in April that found that NGATS programs would cost a total of $18 billion (this
is in addition to the $50 billion that would be needed just to sustain the
existing ATC system between now and 2025) between 2008 and 2025. See also pp. 9-12 for a more detailed
discussion on the ATO and the status of legacy ATC systems. According to JPDO, a more detailed, 5-year
NGATS cost estimate will be included in the Bush Administration’s FY 2008
budget.
Most of the FAA’s current $2.5
billion Facilities and Equipment (F&E) funding goes for sustaining the
existing ATC system, not for new initiatives like NGATS. As a result, there is a significant F&E
funding gap with respect to the cost of sustaining the existing ATC system and
investing in NGATS over the next five years: $500 million in FY 2008; $800
million in FY 2009; $1 billion in FY 2010; $1.2 billion in FY 2011; and $900
million in FY 2012.
Similarly, the Research Engineering
Development Advisory Committee (REDAC), a group established by Congress to advise
FAA on how to spend its research and development dollars, predicts FAA will
face a budget shortfall of about $1 billion annually through 2025 with respect
to the cost of developing NGATS while keeping the existing ATC system running
(this includes funding for F&E, R&D, and operations).
SESAR:
The European Air Traffic Modernization Initiative
The Single European Sky
Air Traffic Research Project, commonly known as SESAR, is essentially the
European equivalent of the JPDO. The
SESAR Consortium, consisting of representatives from a wide-range of industry
groups, is the organization tasked by the European Commission (EC) and
Eurocontrol with planning the future European air traffic management (ATM)
system.
The Consortium, which
began work in March, is currently developing a technological road map for the
future European air traffic management (ATM) system. This road map is part of the project
definition phase - the first of SESAR’s 15-year, three-phase ATM modernization
program. The two-year project definition
phase will conclude in March 2008. The EC
and Eurocontrol have provided $78 million for research and study on the project
definition phase, which is being conducted by Consortium members. The EC is considering a proposal to increase
ATM research to $357 million annually between FY 2007-2013.
Unlike the JPDO, the
Consortium is a bottom-up organization, meaning that the aviation industry is
essentially developing the ATM road map for final approval by Eurocontrol and
the EC. In the
The second phase of
SESAR is the development phase (2008-2013), which will focus on systems design
and producing the key systems components.
The third and final phase is the deployment phase, lasting from 2014 to
2020.
The Present: Overview and Status of
Legacy ATC Modernization Programs
One of the
major challenges confronted by FAA in the near-term is how to replace its aging
air traffic control facilities and obsolete legacy systems given stagnant
Facilities and Equipment account funding and declining aviation trust fund
revenues.
According to
the FAA’s own analysis, two-thirds of its $30 billion worth of assets are
beyond their useful life. Air traffic
control towers average 30 years in age.
TRACON facilities average 34 years.
Primary En Route Radar Systems average 27 years. En Route Control Centers average 40 years and
are rated by General Services Administration (GSA) as being in poor condition.
Congress
appropriated $2.54 billion in F&E funding for fiscal years 2005 and 2006 to
increase the capacity, efficiency, security and safety of the NAS. FAA’s FY 2007 budget includes $2.5 billion
for F&E funding – a reduction of almost $50 million –from the amounts
appropriated by Congress in FY 2005 and FY 2006, and $600 million less than the level authorized by VISION 100 for FY 2007. Of the total
annual F&E budget, approximately 57 percent is used to develop and acquire
ATC modernization projects – the remaining funds support personnel and related
expenses, mission support and FAA facilities.
Air Traffic Organization
The ATO
combined the FAA’s Research and Acquisitions, Air Traffic Services and Free
Flight offices into one organization. It is aligned around the services
delivered to the customers. Headed up by a Chief Operating Officer (COO), Russ
Chew, the ATO has ten service units (safety,
communications, operations planning, finance, acquisition and business
services, en route and oceanic services, terminal services, flight services,
system operations services and technical operations services).
The ATO
inherited the decades-long legacy of cost, schedule, and/or performance
problems with major ATC system acquisitions.
GAO found that only three of 16 major system acquisitions are currently
operating within their original cost, schedule and performance targets. These major system acquisitions had total
cost growth ranging from $1.1 million to about $1.5 billion over their original
cost targets.
Similarly,
the DOT IG found that 11 of the 16 major ATC modernization acquisition programs
will experience a total cost growth of about $5.6 billion, and 9 of the 16
programs will have schedule slips from 2 to 12 years.
Despite the challenges
FAA has had with ATC acquisitions, GAO found that the ATO has made progress in
meeting cost, schedule and performance targets, particularly since the
formation of the ATO. The DOT IG also stated that the bulk of the cost growth
represented by the $5.6 billion occurred before the establishment of the ATO.
The ATO also has cut or
deferred action on three high-risk legacy ATC modernization programs, Next
Generation Communication (NEXCOM), designed to transition analog air‑to‑ground
transmissions to digital; Controller Pilot Datalink Communications (CPDLC),
which would allow digital email-type capability between controllers and pilots;
and Local Area Augmentation System (LAAS), a satellite-based precision-landing
system. Additionally, the ATO has broken
down its troubled Standard Terminal Automation Replacement System (STARS)
acquisition down into more manageable phases (see p. 12).
The ATO has also had
success controlling costs and schedule on two major acquisitions that will
provide new capabilities: the Advanced Technologies and Oceanic Procedures
(ATOP) system that provides new satellite-based surveillance capability over
the ocean; the ongoing En Route Automation Modernization (ERAM) program, a
rewrite of software for high-altitude air traffic management that will serve as
a platform for the next generation system.
Major legacy programs include:
Existing and Potential ATO Cost Savings and Productivity
Initiatives
FAA and the
ATO are currently implementing a wide-range of cost control and savings
initiatives. These initiatives include:
contracting out flight service operations ($2.2 billion in savings over the
next decade); better sick leave management ($59 million in savings); reduction
in night shift operations at selected towers ($34 million in savings); and
telecommunications upgrade (no savings until after 2010). GAO determined that these initiatives could
save about $450 million through fiscal year 2010.[9]
Given the
tight budgetary environment, the ATO is under tremendous pressure to reduce
costs even further. Citing an
independent financial assessment of FAA conducted in 1997 by Coopers &
Lybrand, and a 1997 report by the bipartisan National Civil Aviation Review
Commission (NCARC), chaired by DOT Secretary Norm Mineta, GAO recommended that
the ATO consider a broad range of initiatives that offer potentially
significant cost reductions and productivity improvements, including:
·
Consolidating major air traffic control
facilities – ATO
maintains 21 air traffic control centers, employing about 6,700 controllers, to
serve high-altitude air traffic nationwide.
The Coopers & Lybrand report concluded that the number of these
centers could be reduced without a negative impact on air safety.
·
Consolidate regional offices – FAA maintains nine regional
offices. The Coopers & Lybrand
report and the NCARC report said FAA could achieve savings from consolidating
regional offices. According to the NCARC
report, consolidating nine FAA regional offices into three could save $400
million over a 5-year period.
·
Decommission legacy infrastructure – ATO maintains thousands of
navigational aids to help guide aircraft to their destinations. According to the NCARC and Coopers &
Lybrand reports, decommissioning these navigational aids could result in
significant annual savings - $150 million per year, according to the NCARC
report. The reports both concluded that
FAA should expedite the decommissioning and transition to satellite-based
navigation. The Coopers & Lybrand
report noted that FAA has historically been reluctant to retire these systems,
noting that general aviation users continue to rely on some of these systems
until their aircraft are upgraded to utilize satellite-based navigation.
·
Expand the contract tower program – Although FAA employees staff control
towers at most of the nation’s busiest airports, FAA contracts for outside
staff to work at over 200 airports with lower traffic levels. Both the NCARC and Coopers & Lybrand
reports recommended expanding the contract tower program to achieve savings of an
additional $20 million to $30 million per year.
The DOT IG found that the existing contract tower program is saving the
FAA $175 million annually.
·
Implementation of new ATC technologies – A number of new technologies, including
User Request Evaluation Tool (URET) and ADS-B will improve controller
productivity, increase system efficiency and capacity, enhance safety, and, in
the long-term, possibly reduce the number of controller positions needed.
Other potential cost savings initiatives include leasing, rather
than owning, telecommunications infrastructure, and leasing out sites of closed
NAVAIDS for uses such as cell towers (to generate ongoing revenue).
