The Future Air Traffic Control System
“The Wright Brothers created
the single greatest cultural
force since the invention of
writing. The airplane became
the first World Wide Web,
bringing people, languages,
ideas and values together.”

Overview
• The importance of civil aviation
to the global community
• Aeronautical radio
spectrum – in general
• The global players
• Future aviation technologies
• The way ahead

Civil Aviation Importance
• Total direct impact of
air transport on gross
world output amounts
to at least US$1,360B
• Air transport itself
provides 28 Million jobs worldwide
• Health and welfare…brings people together…makes our
world smaller
• International commerce…business travel…transport of
goods
• Stringent technical requirements for aeronautical safety
systems stretch technological capabilities
-3-
Aeronautical Radio Spectrum
• General goals for aeronautical radio spectrum supporting
international safety services:
– Allocated exclusively
for aviation
– Allocated globally
• Aeronautical radio
spectrum required to:
– Navigate through the
airspace
– Monitor aircraft
movements
– Communications; to provide safe separation and avoid collisions
• Why these requirements?
– Need for high levels of integrity
– Need for high levels of availability

The Global Players
“…the future development of international civil aviation can greatly
help to create and preserve friendship and understanding among the
nations and peoples of the world, yet its abuse can become
a threat to the general security…”
Preamble to the Convention on International Civil Aviation, 1944
• International Civil Aviation Organization (ICAO): Plays the key role in
developing international standardization to implement a truly global air
traffic system; 188 Contracting States
• International Air Transport Association (IATA): Brings together
approximately 270 airlines, including the world’s largest. Flights by these
airlines comprise more than 98% of all international scheduled air traffic
• Eurocontrol, ASECNA, COCESNA, and the
civil aviation authorities: Provide air traffic
control services to ensure safe and
efficient air travel
• International Telecommunication Union: key
agency in providing the global spectrum
allocations needed for global air traffic control
system; ICAO, IATA, Eurocontrol, and other
aviation bodies are observers to ITU and provide inputs on aviation

Future Aviation Technologies
• Civil aviation need to support traffic growth for increased
levels of safety, security and efficiency drives future aviation
requirements
• Communications: primary issue is shortage of bandwidth to
support all air traffic control communications requirements
• Navigation: increased traffic requires
increased navigation accuracy
• Surveillance: goal is to provide the
pilot and controller with more tools
for better situational awareness and
improve safe separation in remote airspace

Spectrum Congestion
…Possible Solutions…
• Need to be able to move
applications to new radio
spectrum
• Adoption of advanced
technology
• New definition(s) for use of aeronautical radio spectrum
by global aviation

Communications Future Technologies
• Currently there are three AM(R)S standards to support
unique requirements around the world:
– Double-sideband, amplitude modulated voice (25 kHz
channelization): used around the world except in parts of core
Europe
– Double-sideband, amplitude modulated voice (8.33 kHz
channelization): used in parts of core Europe due to severe radio
spectrum congestion
– Digital modulation: global standards exist, however, the system
has limited implementation
• International civil aviation is currently
studying its future needs for AM(R)S
spectrum to support air traffic control
communications
– WRC-2007 Agenda Item 1.6
• One of the critical needs: enhanced aviation security
-11-
Navigation Future Technologies
• International civil aviation vision is for a space-based
global navigation system, the Global Navigation Satellite
System (GNSS)
– Lessens the need for ground infrastructure
– Provides true global capabilities
• Several complementary systems
make up the GNSS:
– GLONASS provided by Russian
Federation
– GPS provided by U.S.
– Future Galileo provided by Europe
• Radio spectrum to support a modernized GNSS was
allocated at WRC-2003
-12-
Surveillance Future Technologies
• Goal is to provide more
autonomy to the pilot:
– Allow self-separation in certain
airspace
– Provide air-to-air surveillance in
uncontrolled and remote airspace
– Enhance situational awareness
• ICAO has standardized:
• Mode S extended squitter (1090 MHz)
• VDL-4 (spectrum allocated at WRC2003)
• An additional system, UAT, is currently
being standardized by ICAO and spectrum to
accommodate complete functionality will be
identified at WRC-2007
-13-
The Way Ahead and Issues
• Administrations support ICAO
position as possible in their
Positions and with Proposals to
WRC-2007
• There are many WRC-2007 agenda
items of importance to international
civil aviation; in particular, Agenda
Item 1.6
• In future years, work within ITU to
develop international radio
regulations and allocations that
support the future needs of
international civil aviation
