International Aviation: Next Generation Air Transportation System

The FAA works closely with its international partners to ensure that global air traffic management (ATM) modernization programs are compatible with the Next Generation Air Transportation System (NextGen). By collaborating with industry and leveraging international relationships, the FAA helps shape international standards that improve the safety and efficiency of aviation around the globe. The FAA's NextGen International Office collaborates with key foreign states to leverage ATM knowledge and ensure that NextGen remains at the center of global harmonization. The office maintains international agreements with the European Union, Japan, and Singapore for joint research and development of future air traffic systems. Through these agreements, the FAA engages partners to support the adoption of our system standards as globally accepted standards. The work supports the International Civil Aviation Organization's (ICAO) Global Air Navigation Plan, which aims to harmonize air traffic systems around the world.

Technical Assistance

The FAA's technical assistance programs facilitate delivery of FAA expertise and knowledge to customers around the world. Agreements for the provision of services are conducted on a government-to-government, corporation or organization basis. The recipient country is mandated to reimburse the FAA for the cost of the technical assistance.

The FAA technical assistance agreements cover the entire spectrum of civil aviation activities and include the following:

Training: Each year, FAA arranges training for foreign nationals from more than 60 countries at the FAA Academy and at U.S. industry and academic institutions.

Flight Inspection: FAA flight inspection crews inspect and calibrate navigational aids worldwide.

Loan of Equipment: The FAA supplies other countries with new and used equipment common to the FAA National Airspace System.

Supply Support and Repair Services: Civil aviation authorities are encouraged to obtain spare parts and repair of equipment through FAA.

Cooperative Agreements: Cooperative agreements are arranged with foreign aviation authorities to exchange technical information and pursue joint technical projects, including R&D activities.

In-country Technical Assistance: FAA experts work with other countries to improve aviation safety. Experts are dispatched on short-term assignments to address specific problems and conduct surveys, studies, etc. Long-term assistance is provided by civil aviation assistance groups comprised of resident FAA advisers who assist in the development of a country's aviation system. The FAA has provided experts in the following areas:

  • Systems design and planning
  • Equipment installation and maintenance
  • Airworthiness maintenance
  • Type certification
  • Air traffic control procedures
  • Airport operations and standards

For more detailed information on the technical assistance activities that are available from FAA, please contact the FAA Senior Representative or Desk Officer for your country.

Area Equivalent Method (AEM)

The Area Equivalent Method (AEM) is a screening procedure used to simplify the assessment step in determining the need for further analysis with the Aviation Environmental Design Tool (AEDT) as part of Environmental Assessments and Impact Statements (EA/EIS) and Federal Aviation Regulations (FAR) Part 150 studies. AEM is a mathematical procedure that provides an estimated noise contour area of a specific airport given the types of aircraft and the number of operations for each aircraft. The noise contour area is a measure of the size of the landmass enclosed within a level of noise as produced by a given set of aircraft operations.

The Area Equivalent Method (AEM) is designed for use on Microsoft Windows operating systems under Microsoft Excel. The AEM release consists of two files listed below. The model is currently based on AEDT 2c SP2 and follows a spreadsheet format providing the user with a familiar and user-friendly environment for interfacing with the model.

Aviation Cooperation Program

Aviation Cooperation Programs (ACP) are public-private partnerships designed to consolidate U.S. technical cooperation to promote aviation safety and efficiency in a collaborative manner with aviation interests in foreign countries. The overall ACP strategy fosters cooperation between the U.S. government and corporate aviation members in the delivery of technical programs and assistance, thereby avoiding duplication and maximizing financial benefits for both sides. The principal goals of the ACP are to:

  • facilitate and coordinate U.S. government and aviation industry training and technical cooperation to avoid duplication and promote synergy;
  • increase awareness of U.S. technology, product standards, procedures and services that will assist countries in developing its aviation infrastructure;
  • promote safer operations and more efficient management in the aviation sector; and
  • foster a long-term working relationships between the U.S. aviation community and counterparts in foreign countries.

International Visitors Program (IVP)

Tuesday, July 09, 2024

Each year, approximately 4,000 aviation professionals participate in the International Visitors Program (IVP). Whether touring headquarters, or other FAA facilities throughout the United States, the focus of the IVP is on advancing international cooperation in the research, development, and acquisition of aviation system and technologies that enhance aviation safety.

Through the IVP, we are able to build and foster stronger relationships with civil aviation counterparts and provide foreign visitors with the opportunity to improve their knowledge of agency programs and technologies.

Arranging a Visit

  1. If an individual wishes to visit an FAA Office/Facility, the intended visitor must contact an FAA sponsor to coordinate their visit. The sponsor may be an FAA employee the visitor is already working with, or a country/area-specific employee listed in the FAA API Desk Officers and Senior Representatives.
  2. Prior to submitting an IVP request, the sponsor (an FAA employee) must contact the appropriate staff in the FAA Office of International Affairs (API) for situational awareness, potential concerns, and assistance with planning any visit by a foreign national to an FAA facility.
  3. The sponsor must submit a request on behalf of a foreign national planning a visit to an FAA facility.
  4. Requests must be submitted a minimum of 10 business days in advance of the visit for security to process. Be advised that at times we do experience a backlog of visit requests; therefore, we recommend forms are submitted as far in advance as possible to ensure an approval is received in time for the visit.
    • NOTE: Requests submitted to the system with less than 10 days before the visit cannot be approved by security and are subject to Facility Manager approval without the benefit of identity validation.

For more information on arranging a visit, please contact the API IVP Coordinator, Meg McAbee, APX-10, at 202-267-1000 or Margaret.e.McAbee@faa.gov(Alternate contact: Asia Cunningham, Asia.A-CTR.Cunningham@faa.gov

Details on FAA Noise Levels, Stages, and Phaseouts

Noise Levels

The FAA regulates the maximum noise level that an individual civil aircraft can emit through requiring aircraft to meet certain noise certification standards. These standards designate changes in maximum noise level requirements by "stage" designation. The U.S. noise standards are defined in the Code of Federal Regulations (CFR) Title 14 Part 36 – Noise Standards: Aircraft Type and Airworthiness Certification (14 CFR Part 36). The FAA publishes certificated noise levels in the advisory circular, Noise Levels for U.S Certificated and Foreign Aircraft. This advisory circular provides noise level data for aircraft certificated under 14 CFR Part 36 and categorizes aircraft into their appropriate "stages". Any aircraft that is certified for airworthiness inthe U.S. needs to also comply with noise standard requirements to receive a noise certification. The purpose of the noise certification process is to ensure that the latest available safe and airworthy noise reduction technology is incorporated into aircraft design and enables the noise reductions offered by those technologies to be reflected in reductions of noise experienced by communities. As noise reduction technology matures, the FAA works with the international community to determine if a new stringent noise standard is needed. If so, the international community through the International Civil Aviation Organization (ICAO) embarks on a comprehensive analysis to determine what that new standard will be.

Noise Stages

The current FAA noise standards applicable to new type certifications of jet and large turboprop aircraft is Stage 4. It is equivalent to the ICAO Annex 16, Volume 1 Chapter 4 standards. Recently, the international community has established and approved a more stringent standard within the ICAO Annex 16, Volume 1 Chapter 14, which became effective July 14, 2014. The FAA is adopting this standard and promulgating the rule for Stage 5 that is anticipated to be effective for new type certificates after December 31, 2017 and December 31, 2020, depending on the weight of the aircraft. The Notice of Proposed Rule Making (NPRM) for Stage 5 was published on January 14, 2016.

For helicopters, the FAA has noise standards for a Stage 3 helicopter that became effective on May 5, 2014. These more stringent standards apply to new type helicopters and are consistent with ICAO Annex 16, Volume 1 Chapter 8 and Chapter 11.

Prohibitions

The FAA Modernization and Reform Act of 2012, in Section 513, had a prohibition on operating certain aircraft weighing 75,000 pounds or less not complying with Stage 3 noise levels, and on July 2, 2013, the FAA published a Final Rule in the Federal Register for the Adoption of Statutory Prohibition the Operation of Jets Weighing 75,000 Pounds or Less That Are Not Stage 3 Noise Compliant.In 1990, Congress passed the Aviation Noise and Capacity Act, which required that by the year 2000 all jet and large turboprop aircraft at civilian airports be Stage 3.

Aviation Environmental Tools Suite

The Environment & Energy (E&E) Research and Development (R&D) Portfolio is supporting the development of a comprehensive suite of analytical tools to quantify the environmental consequences and impacts of aviation. At the center of these analytical tools is the Aviation Environmental Design Tool (AEDT), which can quantify the noise, fuel burn and emissions resulting from all aspects of aircraft operations. This tool is designed to model individual studies ranging in scope from a single flight at an airport to scenarios at regional, national, and global scales. The other tools in the suite are designed to complement the AEDT capabilities by generating data to be used as input or processing outputs to develop additional information. 

AEDT is the required tool for the environmental review of infrastructure projects and other Federal actions affecting airports and airspace in the United States. In addition to being a required tool for Federal actions, AEDT has a broader use both domestically and internationally. The tool is used by aviation professionals, researchers, manufacturers, airlines, airports, and other national aviation authorities to address a variety of environmental questions associated with aircraft operations.  Additionally, the Aviation Environmental Tool Suite supports the analysis needs of the International Civil Aviation Organization’s (ICAO) Committee on Aviation Environmental Protection (CAEP).  The suite is used to develop analysis scenarios required by the ICAO CAEP’s work programs and AEDT is the primary tool for the computations of the worldwide results that inform CAEP decisions.

The Aviation Environmental Tools Suite capabilities are continuously being improved and expanded to adapt to the evolving nature of the aviation system and its components.  The E&E R&D Portfolio supports tools research and development activities through the U.S. DOT Volpe Center and the Aviation Sustainability Center (ASCENT), the FAA’s Center of Excellence (COE) for Alternative Jet Fuels and Environment, and in coordination with other federal agencies including National Aeronautics and Space Administration (NASA) and the U.S. Environmental Protection Agency (EPA).
