RTCA, Inc. (formerly known as Radio Technical Commission for Aeronautics) is a United States non-profit organization that develops technical guidance for use by government regulatory authorities and by industry. It was founded in 1935, and was re-incorporated in 1991 as a private not-for-profit corporation. It has over 20 active committees with multiple working groups under each committee and develops industry standards in cooperation with aviation regulators from around the world including the FAA.
Requirements for membership are limited to organizations (e.g., private industry, government, academic, and research and development) that have an interest and skill in the aviation industry and are willing to provide those skills through the work of their employees who volunteer their time and energy to produce usable and complete engineering standards documents. Standards are developed and drafted by Special Committees (SC) and are approved by the Program Management Committee, which oversees the activities of the Special Committees. Documents are developed are consensus documents meaning that all participants can agree with the content, not that they agree 100% with everything that is said in the document.
RTCA develops Minimum Operating Performance Standards for aviation based technology (typically avionics) but has developed standards for such far-ranging topics as Airport Security, Counter UAS Detection standards and Aircraft Cockpit and Cabin Cleaning standards.
The documents of RTCA include:
RTCA is not an agency of the United States government but works with regulators around the globe to develop standards that may be referenced in their regulatory framework. RTCA is an official observer to the International Civil Aviation Organization (ICAO).
A traffic collision avoidance system or traffic alert and collision avoidance system is an aircraft collision avoidance system designed to reduce the incidence of mid-air collisions between aircraft. It monitors the airspace around an aircraft for other aircraft equipped with a corresponding active transponder, independent of air traffic control, and warns pilots of the presence of other transponder-equipped aircraft which may present a threat of mid-air collision (MAC). It is a type of airborne collision avoidance system mandated by the International Civil Aviation Organization to be fitted to all aircraft with a maximum take-off mass (MTOM) of over 5,700 kg (12,600 lb) or authorized to carry more than 19 passengers. CFR 14, Ch I, part 135 requires that TCAS I be installed for aircraft with 10-30 passengers and TCAS II for aircraft with more than 30 passengers. ACAS/TCAS is based on secondary surveillance radar (SSR) transponder signals, but operates independently of ground-based equipment to provide advice to the pilot on potentially conflicting aircraft.
Basel II is the second of the Basel Accords,, which are recommendations on banking laws and regulations issued by the Basel Committee on Banking Supervision.
A type certificate signifies the airworthiness of a particular category of aircraft, according to its manufacturing design. It confirms that the aircraft of a new type intended for serial production, is in compliance with applicable airworthiness requirements established by the national air law.
DO-178B, Software Considerations in Airborne Systems and Equipment Certification is a guideline dealing with the safety of safety-critical software used in certain airborne systems. It was jointly developed by the safety-critical working group RTCA SC-167 of the Radio Technical Commission for Aeronautics (RTCA) and WG-12 of the European Organisation for Civil Aviation Equipment (EUROCAE). RTCA published the document as RTCA/DO-178B, while EUROCAE published the document as ED-12B. Although technically a guideline, it was a de facto standard for developing avionics software systems until it was replaced in 2012 by DO-178C.
A hazard analysis is used as the first step in a process used to assess risk. The result of a hazard analysis is the identification of different type of hazards. A hazard is a potential condition and exists or not. It may in single existence or in combination with other hazards and conditions become an actual Functional Failure or Accident (Mishap). The way this exactly happens in one particular sequence is called a scenario. This scenario has a probability of occurrence. Often a system has many potential failure scenarios. It also is assigned a classification, based on the worst case severity of the end condition. Risk is the combination of probability and severity. Preliminary risk levels can be provided in the hazard analysis. The validation, more precise prediction (verification) and acceptance of risk is determined in the Risk assessment (analysis). The main goal of both is to provide the best selection of means of controlling or eliminating the risk. The term is used in several engineering specialties, including avionics, chemical process safety, safety engineering, reliability engineering and food safety.
ARP4761, Guidelines and Methods for Conducting the Safety Assessment Process on Civil Airborne Systems and Equipment is an Aerospace Recommended Practice from SAE International. In conjunction with ARP4754, ARP4761 is used to demonstrate compliance with 14 CFR 25.1309 in the U.S. Federal Aviation Administration (FAA) airworthiness regulations for transport category aircraft, and also harmonized international airworthiness regulations such as European Aviation Safety Agency (EASA) CS–25.1309.
RTCA DO-254 / EUROCAE ED-80, Design Assurance Guidance for Airborne Electronic Hardware is a document providing guidance for the development of airborne electronic hardware, published by RTCA, Incorporated and EUROCAE. The DO-254/ED-80 standard was formally recognized by the FAA in 2005 via AC 20-152 as a means of compliance for the design assurance of electronic hardware in airborne systems. The guidance in this document is applicable, but not limited, to such electronic hardware items as
DO-242A is an aviation system standard published by RTCA, Incorporated. It contains minimum aviation system performance standards (MASPS) for Automatic Dependent Surveillance-Broadcast (ADS-B). These standards specify operational characteristics that should be useful to designers, manufacturers, installers, service providers and users of an ADS-B system intended for operational use on an international basis. DO-242A provides a view of the system-wide operational use of ADS-B, but does not describe a specific technical implementation or design architecture meeting these operational and technical characteristics.
The European Organisation for Civil Aviation Equipment (EUROCAE) deals exclusively with aviation standardisation, for both airborne and ground systems and equipment. It was created in 1963 in Lucerne, Switzerland by a decision of the European Civil Aviation Conference as a European forum focusing on electronic equipment for air transport.
ISO 13485Medical devices -- Quality management systems -- Requirements for regulatory purposes is an International Organization for Standardization (ISO) standard published for the first time in 1996; it represents the requirements for a comprehensive quality management system for the design and manufacture of medical devices. This standard supersedes earlier documents such as EN 46001 and EN 46002 (1996), the previously published ISO 13485, and ISO 13488.
DO-160, Environmental Conditions and Test Procedures for Airborne Equipment is a standard for the environmental testing of avionics hardware. It is published by the Radio Technical Commission for Aeronautics (RTCA) and supersedes DO-138.
The Directorate General of Civil Aviation (DGCA) is a statutory body of the Indian Central Government to regulate civil aviation in India. Formed under the Aircraft (Amendment) Bill, 2020, the DGCA investigates aviation accidents and incidents, maintains all regulations related to aviation and is responsible for issuance of licenses pertaining to aviation like PPL's, SPL's and CPL's in India. It is headquartered along Sri Aurobindo Marg, opposite Safdarjung Airport, in New Delhi. The Government of India is planning to replace the organisation with a Civil Aviation Authority (CAA), modelled on the lines of the American Federal Aviation Administration (FAA).
Functional safety is the part of the overall safety of a system or piece of equipment that depends on automatic protection operating correctly in response to its inputs or failure in a predictable manner (fail-safe). The automatic protection system should be designed to properly handle likely human errors, hardware failures and operational/environmental stress.
The Brazilian Organization for the Development of Aeronautical Certification is a nonprofit organization, of public interest, regulated by Brazilian Law number 9.790 as of March 23, 1999, and registered at the Brazilian Ministry of Justice on November 28, 2006.
DO-178C, Software Considerations in Airborne Systems and Equipment Certification is the primary document by which the certification authorities such as FAA, EASA and Transport Canada approve all commercial software-based aerospace systems. The document is published by RTCA, Incorporated, in a joint effort with EUROCAE, and replaces DO-178B. The new document is called DO-178C/ED-12C and was completed in November 2011 and approved by the RTCA in December 2011. It became available for sale and use in January 2012.
Regulatory science is the scientific and technical foundations upon which regulations are based in various industries – particularly those involving health or safety. Regulatory bodies employing such principles in the US include for example the FDA for food and medical products, the EPA for the environment, and OSHA for work safety.
The Worker Protection Standard is intended to protect employees on farms, forests, nurseries, and greenhouses that are occupationally exposed to agricultural pesticides.
Diver training is the set of processes through which a person learns the necessary and desirable skills to safely dive underwater within the scope of the diver training standard relevant to the specific training programme. Most diver training follows procedures and schedules laid down in the associated training standard, in a formal training programme, and includes relevant foundational knowledge of the underlying theory, including some basic physics, physiology and environmental information, practical skills training in the selection and safe use of the associated equipment in the specified underwater environment, and assessment of the required skills and knowledge deemed necessary by the certification agency to allow the newly certified diver to dive within the specified range of conditions at an acceptable level of risk. Recognition of prior learning is allowed in some training standards.
A diver training standard is a document issued by a certification, registration regulation or quality assurance agency, that describes the prerequisites for participation, the aim of the training programme, the specific minimum competences that a candidate must display to be assessed as competent, and the minimum required experience that must be recorded before the candidate can be registered or certified at a specific grade by the agency. A standard is a description of the quality required of a product, or a way of doing something that has usually been derived from the experience of experts in a specific field. The purpose is to provide a reliable method for people to share a reasonably consistent expectation regarding the scope and quality of the product or service. Training standards allow objective comparison between the training provided by various agencies and the competence indicated by certification or registration to the specific standard, though in most cases, training and competence may exceed the minimum requirement much of the time, and variation between newly certified divers can be considerable, partly due to differences in the training, and partly due to qualities of the candidate. Training standards may narrowly prescribe the training, or may concentrate on assessment of exit level competence, and allow recognition of prior learning based on various forms of evidence. To be useful, a training standard must be sufficiently specific to allow agreement on the requirements by most readers reasonably competent in the field, including the instructors, assessors, and learners who must use it, the employers of persons trained, the potential customers, and any quality assurance personnel who may need to enforce it. A training standard may be linked to a code of practice referring to how the training should be carried out.
Recreational scuba certification levels are the levels of skill represented by recreational scuba certification. Each certification level is associated with a specific training standard published by the certification agency, and a training programme associated with the standard., though in some cases recognition of prior learning can apply. These levels of skill can be categorised in several ways:
