Increased efficiency and safety
The main drivers for ATM_cns are to
further improve safety and to reduce
system inefficiencies such as congestion
and delays while increasing airspace and
airport capacity. For example, digital data
communications between flight crews and
controllers drastically reduce the potential
for errors, and enable reduced aircraft
separation.
Shortened flight times
and optimum routings
GNSS is available worldwide, and
communication satellite signals are
available in many oceanic and remote
areas. This means that the implementation
of certain elements of ATM_cns can
provide immediate improvements to
communications, navigation and
surveillance in regions that were previously
"out of bounds" due to low quality or nonexisting
radio coverage. The ability of pilots
to determine and request clearance along
their own direct flight paths using satellite
navigation rather than following pre-defined
flight paths will enable optimum routings
and shortened flight times.
Air transport safety, efficiency and growth driven by market demand
Benefits
ATM_cns will address the limitations of the current systems, and will provide many
improvements in safety, efficiency, environmental performance and capacity – thus
responding to rising consumer demand for sustainable air travel.
Environmental improvements
Shortened flight times will result in greater
fuel efficiency and fewer aircraft emissions
– as confirmed by the United Nations’
Intergovernmental Panel for Climate
Change (IPCC) Special Report on Aviation
and the Global Atmosphere (1999), which
states that the ICAO CNS/ATM Systems
Concept, once fully implemented on a
worldwide basis, will have the potential to
further improve overall fuel efficiency by 6-
12% – representing an annual reduction of
around 20 million tonnes of carbon dioxide
(CO 2) emissions and a cost saving of
between USD 4.3 and 6 billion per year for
the industry and its customers.

Global applicability and
cost-effectiveness
Some remote regions and developing
countries still lack an appropriate "cns"
infrastructure thus making it impossible
to safely meet the needs of modern civil
aviation. The cost of providing and
maintaining such infrastructure is
increasing.
The ATM_cns concept is globally
applicable and less dependent on the
number of expensive ground-based aids.
This will make it more cost-effective for
States to implement ATM_cns whilst
also reducing future acquisition and
maintenance costs.
