System Wide Information Management

Last updated

System Wide Information Management (SWIM) is a global Air Traffic Management (ATM) industry initiative to harmonize the exchange of Aeronautical, Weather and Flight information for all Airspace Users and Stakeholders. SWIM is an integral part of the International Civil Aviation Organization (ICAO) Global Air Navigation Plan (GANP) . The GANP defines 4 Performance Improvement Areas (PIA), SWIM resides in PIA 2: Globally interoperable systems and data, where its implementation is further defined in Aviation System Block Upgrades (ASBU) B1-SWIM and B2-SWIM. ASBU B1-SWIM defines SWIM as a “a net-centric operation where the air traffic management (ATM) network is considered as a series of nodes, including the aircraft, providing or using information.” it goes on to say “The sharing of information of the required quality and timeliness in a secure environment is an essential enabler to the ATM target concept.” [1]

ICAO Annex 3 defines what IWXXM capability is required at different time frames. These capabilities can also be considered in context of the ICAO SWIM-concept (Doc 10039, Manual on System Wide Information Management (SWIM) Concept). [2]

Eurocontrol initially presented the SWIM System concept to the Federal Aviation Administration (FAA) in 1997 and in 2005, the ICAO Global ATM Operational Concept adopted the SWIM concept to promote information-based ATM integration. SWIM is now part of development projects in the United States (Next Generation Air Transportation System, or NextGen), the Middle East (GCAA SWIM Gateway) and the European Union (Single European Sky ATM Research).

Within the FAA, the FAA SWIM program is an advanced technology program designed to facilitate greater sharing of ATM system information, such as airport operational status, weather information, flight data, status of special use airspace, and National Airspace System (NAS) restrictions. SWIM will support current and future NAS programs by providing a flexible and secure information management architecture for sharing NAS information. SWIM will use commercial off-the-shelf hardware and software to support a Service Oriented Architecture (SOA) that will facilitate the addition of new systems and data exchanges and increase common situational awareness. SWIM is part of FAA's NextGen, an umbrella term for the ongoing evolution of the United States' NAS from a ground-based system of air traffic control (ATC) to a satellite-based system of air traffic management. The transformation to NextGen requires programs and technologies that provide more efficient operations, including streamlined communications capabilities. The SWIM program is an integral part of that transformation that will connect FAA systems. The SWIM program will also enable interaction with other members of the decision-making community including other government agencies, air navigation service providers, and airspace users. The SWIM program will lead to a variety of benefits. SWIM will help improve aviation safety through increased common situational awareness by allowing more decision makers to access the same information. This will provide consistent information to different users (pilots, controllers, dispatchers) that supports proactive decision-making.

SWIM as a concept is essential to providing the most efficient use of airspace, managing air traffic around weather, and increasing common situational awareness on the ground. SWIM core services will enable systems to request and receive information when they need it, subscribe for automatic receipt, and publish information and services as appropriate. This will provide for sharing of information across different systems. This will allow airspace users and controllers to access the most current information that may be affecting their area of responsibility in a more efficient manner. SWIM will improve decision-making and streamline information sharing for improved planning and execution.

SWIM will also help reduce infrastructure costs by decreasing the number of unique interfaces between systems. Initially, SWIM will provide a common interface framework, reducing the operation and maintenance costs of current interfaces. New systems will interface with each other via SWIM-compliant interfaces, thereby reducing future data interface development costs. Ultimately, redundant data sources will no longer be needed, and associated systems will be decommissioned.

SWIM is one of the key component of the SESAR (Single European Sky ATM Research) programme managed by the SESAR Joint Undertaking

<span class="mw-page-title-main">Air traffic control</span> Public service provided for the purpose of maintaining the safe and orderly flow of air traffic

Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC worldwide is to prevent collisions, organize and expedite the flow of air traffic, and provide information and other support for pilots.

Free flight is a developing air traffic control method that uses no centralized control. Instead, parts of airspace are reserved dynamically and automatically in a distributed way using computer communication to ensure the required separation between aircraft. This new system may be implemented into the U.S. air traffic control system in the next decade. Its potential impact on the operations of the national airspace system is disputed, however.

NATS Holdings, formerly National Air Traffic Services and commonly referred to as NATS, provides en-route air traffic control services to flights within the UK flight information regions and the Shanwick Oceanic Control Area. It also provides air traffic control services to 14 UK airports.

<span class="mw-page-title-main">Automatic Dependent Surveillance–Broadcast</span> Aircraft surveillance technology

Automatic Dependent Surveillance–Broadcast (ADS-B) is an aviation surveillance technology and form of Electronic Conspicuity in which an aircraft determines its position via satellite navigation or other sensors and periodically broadcasts its position and other related data, enabling it to be tracked. The information can be received by air traffic control ground-based or satellite-based receivers as a replacement for secondary surveillance radar (SSR). Unlike SSR, ADS-B does not require an interrogation signal from the ground or from other aircraft to activate its transmissions. ADS-B can also receive point-to-point by other nearby equipped "ADS-B In" equipped aircraft to provide traffic situational awareness and support self-separation. ADS-B is "automatic" in that it requires no pilot or external input to trigger its transmissions. It is "dependent" in that it depends on data from the aircraft's navigation system to provide the transmitted data.

Remote and virtual tower (RVT) is a modern concept where the air traffic service (ATS) at an airport is performed somewhere other than in the local control tower. Although it was initially developed for airports with low traffic levels, in 2021 it was implemented at a major international airport, London City Airport.

Aircraft self-separation is the capability of an aircraft maintaining acceptably safe separation from other aircraft without following instructions or guidance from a referee agent for this purpose, such as air traffic control. In its simplest forms, it can be described by the concept of see and avoid, in the case of human-piloted aircraft, or sense and avoid, in the case of non-human piloted aircraft. However, because of several factors such as weather, instrument flight rules and air traffic complexity, the self-separation capability involves other elements and aspects such as rules of the air, communication technologies and protocols, air traffic management and others.

IWXXM is a format for reporting weather information in XML/GML. IWXXM includes XML/GML-based representations for products standardized in International Civil Aviation Organization (ICAO) Annex III, such as METAR/SPECI, TAF, SIGMET, AIRMET, Tropical Cyclone Advisory (TCA), Volcanic Ash Advisory (VAA), Space Weather Advisory and World Area Forecast System (WAFS) Significant Weather (SIGWX) Forecast. IWXXM products are used for operational exchanges of meteorological information for use in aviation.
