Two major SWIM features allow more efficient data sharing among Aviation Partners than ever before possible:
- SWIM streamlines connections among different data systems so that users can now access multiple systems through one connection. Previously, a new connection needed to be created every time someone wanted to access a set of data. SWIM was created to eliminate the need to have point to point connections every time a user wants to access the data they need. With SWIM, there is a standard connection instead of a unique connection created every time.
- SWIM also translates data from different systems into standard data formats, thereby supporting collaboration among industry and governments both within the U.S. and around the world (international, FAA internal, Airlines, Service Providers, etc.).
General
- We work with data producers to collect the information they have access to so it can be shared through a single source.
- We work with data consumers to provide easy access to the information they need.

SWIM continues to add NAS Air Traffic Management content providers and consumers. There are at least three more years of data publisher on-ramping to aid additional NAS and Mission Support information, including several new FAA programs such as Common Support Service-Weather and the Terminal Flight Data Manager. This SWIM growth and maturity will enable cost effective and efficient exchange of NAS information and increasing levels of interoperability.
Some road-map items for the five year forecast of FAA SWIM include extensive international exchange of ATM data as well as accommodating very high levels of quality of service such as mission and safety critical data services with data standards. By doing so, FAA SWIM will have the flexibility to more easily connect to networks in regions with some of the heaviest air traffic in the world.

- SWIM makes it possible to have access to real-time, relevant, and reliable aeronautical, flight, and weather information so users (both within the NAS and outside of the NAS) can respond faster and more accurately.
- SWIM helps to reduce implementation and operating costs and increase agility for the air traffic community...to do MORE with LESS.
- SWIM creates collaboration opportunities across borders to address some of aviation's most complex problems.
- By offering efficient and streamlined access to a rich source of aviation data, SWIM stimulates innovation in the public and private sectors to address the needs of aviation partners and the general public.
- SWIM enables the Aviation Community to drive innovation and create value-added products to create a better in-flight experience for the flying public.
- While SWIM is not visible to the flying public, passengers experience the benefits because air traffic management, pilots, and controllers can all manage the airspace more efficiently. Lower infrastructure costs and higher efficiency standards lead to fewer delays, less time airborne, and the benefits of less impact on the environment.
Benefits & Objectives
- Reduce costs for all NAS users of NAS data
- Improve aviation safety and efficiency through common situational awareness
- Deliver consistent information to different users (pilots, controllers, dispatchers) that support proactive decision-making
- Provide a secure data exchange among the NAS user community that meets FAA's security standards
Benefits & Objectives
In the past, the state of the art for connecting two systems required a fixed network connection and custom, point-to-point, application level interfaces. In 2007, FAA identified a need to reduce the high degree of interdependence among these systems. With it came the establishment of SWIM.
Becoming the data sharing backbone of the FAA, SWIM aided common situational awareness, and improved the National Airspace System's (NAS) agility through its information-sharing platform that offers data publishing through a single connection to many consumers including airports, airlines, and the aviation industry. With this new found flexibility, SWIM consumers are able to use multiple types of aviation data in standard formats to create applications and more easily convey aviation information. This leads to many immediate benefits that are just being realized. For example:
- The FAA can now efficiently maximize coordination among data stakeholders to better manage air traffic
- Pilots have electronic access to critical updates such as power outages and airspace restrictions
- Industry is able to leverage the SWIM network to develop applications to suit the needs of the flying public
- The transition to the global harmonization of air traffic is being accelerated through governance to increase data accuracy in regard to flight safety
Benefits & Objectives
The transformation to NextGen requires programs and technologies to provide more efficient operations, including streamlined communications capabilities. The SWIM program is an integral part of that transformation to connect FAA systems. SWIM enables interaction with other members of the aviation decision-making community including other government agencies, air navigation service providers, and airspace users.
Internationally, SWIM is directly influencing the way that aviation stakeholders address the quickly growing, global air traffic community. Information management tools are essential for efficient, cross-border air traffic management, and the groups with the most data readily available to them will benefit the most. By allowing air navigation service providers to connect and share more, the same benefits that are becoming available in the United States are also being implemented globally.
Currently, SESAR, an international group founded by European Union agency members that provides ATM expertise and services to its member states, is working on its own SWIM solutions and regularly collaborates with the FAA (http://www.sesarju.eu/discover-sesar/history). To help this effort, the FAA is collaborating with dozens of international stakeholders through its Mini-Global program by testing new international SWIM concepts.
Benefits & Objectives
SWIM's use of Service Oriented Architecture (SOA) technology allows software applications in the NAS to interact with one another through information services that can be accessed without knowledge of an application's underlying platform implementation. This simplifies interface requirements to existing NAS systems and ensures new systems can be built with minimum technology (hardware, software, and data definition) constraints. Thus, NAS development and implementation costs and risks for new applications will be lower. SWIM also enables the transition to Net-Centric NAS operations, and from tactical conflict management to strategic, trajectory-based operations. The benefits of implementing SOA in the NAS can be summarized as follows:
- Business and Information Technology (IT) Alignment
- Adaptability
- Interoperability
- Reuse
- Scalability

SWIM streamlines shared information for improved planning and execution. Airlines and other users are able to more efficiently access the most current information affecting their area than they were able to using legacy systems, thereby improving decision-making. For example, this may result in fewer delays at major airports, reduced flight congestion, and less fuel costs for airlines by avoiding unnecessary reroutes around severe weather. SWIM provides improved situational awareness to air traffic controllers.
A specific SWIM application - the SWIM Visualization Tool (SVT) - has offered many benefits to the FAA's Southern California Terminal Radar Approach Control (TRACON) Facility (SCT), including:
- Improved Traffic Management Coordinator's (TMC) ability to quickly (at a glance) understand and/or confirm aircrafts ability to make departure release times based on taxiway queues;
- Improved ability of TRACON to understand and manage airspace demand based on what they can see is coming using aircraft and data block color coding;
- Coordination of airspace for air traffic departing in opposite directions, e.g., provides a better understanding of where the actual traffic is when aircraft are departing and arriving opposite direction, east-bound departures and west-bound arrival traffic out of San Diego (SAN);
- Confirmation of landings in bad weather, i.e., heavy rain occasionally creates loss of low altitude surveillance tracks in ATC system...SVT allows TRACON to confirm if the aircraft has landed or not. This is also helpful when aircraft are given release and void times after or before a Tower opens. When the aircraft misses their departure window you can look at the SVT to see if the airplane is still safe on the ground.
- Situational awareness of airport surface traffic complexities caused by anomalous events such as runway or taxiway closures due to construction, surface incidents, foreign object debris (FOD) removal, or disabled aircraft (i.e., it furnishes TRACON personnel insight into the ground controller's workload and time constraints in moving aircraft on and about a specific airport surface);
- Coordination and confirmation of aircraft ready to be released for departure (during periods of high-demand and congested condition) which improves the TRACON's ability to manage airspace and reduces TRACON-to-tower telephone communications.

SWIM was implemented with the mission to be a technology enabler that provides the information technology standards, infrastructure and governance necessary for NAS systems. SWIM shares information, improves interoperability, and reuses information and services with a vision of establishing common processes and infrastructure needed for NextGen. This makes data more accessible for aviation stakeholders, including those outside of the United States.
The FAA has already demonstrated providing SWIM data to National Air Traffic Services (NATS), the ANSP to the United Kingdom. In addition, the SWIM Program Office is actively working with Eurocontrol to connect them as a data consumer on the FAA SWIM System. By being provided more aviation data such as flight planning information, these nations can better manage their air traffic operations and better collaborate with the NAS.

One of the key challenges of implementing SWIM is keeping pace with the demand of on-ramping additional data publishers and consumers. The SWIM network provides flexibility with its NAS Air Traffic Management operational content, which has increased its popularity and the number of its consumers. Some of these types of data that are driving demand include airport surface information, accurate flight tracking, and digital Notices to Airmen (NOTAMs). Currently, the FAA is working to give data access to more than 200 individual consumers, both inside the United States and abroad.
Maintaining currency with data interoperability and governance is also an important challenge to FAA SWIM. The maturing of international data format interoperability standards such as FIXM, AIXM, and WXXM is important to track, adopt and support. Including the international messaging standards such as the new 2014 AMQP v1.0 that substantially facilitate international interoperability is a key aspect to ensuring this challenge is met.
