iv. FUTURE PLANS iv.1 The Air Traffic Management (ATM) System within the NAT Region is continually reviewed in the light of existing structural system shortcomings, the anticipated evolution of air traffic demand and technological advances in airborne and ground based systems. The major shortcoming affecting the vast majority of the NAT Region is the lack of real-time surveillance that severely limits airspace capacity and imposes significant constraints on aircraft flight profiles. iv The introduction of satellite Communications, Navigation and Surveillance (CNS) systems will provide the capability to improve the efficiency, integrity and capacity of the NAT ATM system. The NAT SPG aims to take advantage of new technology, in particular Aeronautical Mobile Satellite Services (AMSS), and achieve a smooth evolution from the present ATM system into the future NAT ATM system. v. CONTACT INFORMATION v.1 This Document will be placed on a number of Web Sites and made available to users via the Internet. It is accessible (as is the ‘North Atlantic MNPS Airspace Operations Manual’)on the following Web Site http://www.nat-pco.org.
