Implementation
The implementation of ATM_cns will have important implications for States
in the way their airspace will be structured and managed.
Relying on satellite systems
States will have a greater reliance on
satellite systems that may be provided and
operated by foreign entities – public or
private – outside their immediate control.
This will require specific international
guarantees ensuring, for example, the
permanent availability and reliability of
satellite signals, as well as their
accessibility without any form of
discrimination. An ICAO Charter already
addresses such issues, but a more formal
international Convention could become
necessary in the long-term in order to
resolve institutional issues, including
liability questions.
Systems must be harmonised,
compatible and interoperable
The success of ATM_cns is dependent
upon global harmonisation, compatibility
and interoperability of service providers,
procedures and on-board and ground
equipment – which, in turn, will have a
positive impact on the safety, reliability
and the cost of operations. For example,
airlines must be able to move from one
GNSS system to another without
duplicating their on-board equipment.

Existing cooperative measures
EUROCONTROL and the United
States (US) Federal Aviation
Administration (FAA) are working
together to ensure the harmonisation
of technical requirements and
procedures.
The Air Traffic Alliance (a grouping
of EADS, Airbus and Thales) and
Boeing's Air Traffic Management
(ATM) business unit are cooperating
on interoperability of future ATM
networks to accelerate existing air
traffic modernisation efforts, foster
new initiatives and jointly address
issues affecting future global
operational efficiency and safety.
