The Global Air Navigation Plan (Doc 9750), contains guidelines regarding the improvements necessary to establish air navigation systems, to make the transition to the Procedures for Services Air Navigation, Air Traffic Control (PANS-ATC) Procedures for Air Navigation, Air Traffic Management (PANS-ATM).
ATM (Air Traffic Management) represents the evolution of air traffic control, incorporates concepts, regulations and procedures related to safety management of air traffic services and the management of air traffic flow.
As the ATM system envisaged is based on the decision-making "in collaboration" is electronic information needed reliable, high quality, available in a timely manner, both aircraft, such as weather, airspace and flow management.
ATM environment is constantly evolving. Application Air Navigation RNAV enables aircraft to move in any desired path without passing through predefined points by ground-based navaids.
providers of air navigation services, with the RNAV intend to conduct more traffic volume in the same space and in the same period of time, ie increase system capacity without degrading security it operational. On the contrary, they increase it.
Among other things, required navigation performance (RNP) to fly in these areas RNAV and ATM requirements, require the AIS higher quality and timeliness, and the transition from the role of a Service AIS Aeronautical Information Management (AIM).
And here comes the first difficulty. While all of society uses the Internet daily, satellite navigation and computer networks, the dissemination of aeronautical information (AIS) is still based on paper maps, paper and telex messages.
Existing systems are disconnected from each other, embodying the same data more than once on different computers using the keyboard instead of transferring files.
This generates errors in the information. Aeronautical information is crucial to allow airspace users can shape the ATM system, help you understand your options and make safe.
The global ATM operational concept defines seven components that make up the future ATM system:
- Organization and management of airspace.
- Airport operations.
- The balance between demand and capacity.
- Traffic synchronization.
- Conflict management.
- operations airspace users.
- The management of the provision of ATM services.
navigation systems and management systems rely on air traffic data. The concept of air traffic management globally threatened implementation of technological asymmetries between the different regions of the world and the fact that currently there is no better access to global information, comprehensive and higher quality and timeliness.
is why we designed a roadmap for the global transition Aeronautical Information Service (AIS) to the Aeronautical Information Management (AIM).
What should primarily change for the transition from AIS to AIM?
should be making greater use of information technology in information management, with greater emphasis on digital data.
Currently, report pre-flight information (GDP) often contain information irrelevant to the flight, due to insufficient filtering possibilities of current NOTAM format. Besides the GDP are often difficult to read and interpret because of the lack of possibilities graphics (they are just text), and the current virtual reality technology allows information to be presented to the user by combining text with 3D digital images.
As is increasingly common to find display screens of electronic charts in the cockpit must be updated rules and symbols to suit the electronic display so that their use is common in the future.
should be secure digital data transfer between air and ground allowing on-screen display aeronautical and meteorological information directly from the aircraft at any stage flight.
The concept requires that all aeronautical information, including that contained in the Aeronautical Information Publication (AIP) is stored as standard data sets that can be accessed from the user's applications.
expected to prevail is the need for aeronautical data will come into force internationally agreed dates, but the use of computer technology, will shorten the current 28-day AIRAC cycle, based on the maximum estimated time for postal delivery of printed products on paper.
The transition from AIS to AIM will be in three stages:
Phase I - Consolidation : action will be taken that will affect areas relating to:
. the quality requirements;
. the compliance AIRAC;
. implementation of sistema de referencia normalizado adoptado para coordenadas (Sistema geodésico mundial–1984) y
. la provisión de datos de sobre el terreno y los obstáculos.
En la primera fase se reforzarán los SARPS de los productos existentes (NOTAM, PIB, etc.) a efectos de meet the requirements of users in the short term.
Phase II - Step into the digital environment : it will focus on the introduction of digital databases are highly structured, as well as tools such as geographic information systems.
Third phase - Information Management: This phase will use the input data sets in the second phase for transferring digital information by implementing the operational concept of global air traffic management in an information environment focused on network connections.
