RTCA DO-254 Design Assurance Guidelines for Airborne Electronic Equipment

The RTCA DO-254 standard, published by the Radio Technical Aviation Commission (RTCA), is a standard that provides guidance for the development of airborne electronic equipment. This standard was recognized by the American Federal Aviation Administration (FAA) in 2005 as a means of conformity for the design assurance of electronic equipment in airborne systems.

The guidance of the RTCA DO-254 standard is considered valid for the following electronic hardware elements, including but not limited to:

• Line replaceable components (quick change components)
• Circuit board assemblies
• Specialized microcode components such as field programmable gate arrays, programmable logic devices, application-specific integrated circuits, and application-specific integrated circuits including any associated macro functions
• Integrated technology components such as hybrid integrated circuits and multi-chip modules
• Commercial ready-to-use components

The RTCA DO-254 standard aims to help aircraft manufacturers and aircraft electronic systems suppliers to ensure that electronic airborne equipment safely performs its intended function. This standard defines the design lifecycle processes for various types of equipment. It also characterizes the purpose of design lifecycle processes and provides a means of compliance and compliance with certification requirements..

Simply put, the RTCA DO-254 standard is a requirements-based process-oriented safety standard used in commercial electronics entering aircraft. Conceptually, this standard applies to all electronic devices that fly or may crash and pose a danger to humans.

Depending on their safety criticality, different levels of design assurance are assigned to different parts of the aircraft. This criticality is determined by a safety assessment of the aircraft and interacting systems to determine the required target failure rate. Because the RTCA DO-254 standard is a process-oriented standard, it is important to understand the general flow of testing.

Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides test services for design assurance for airborne electronic equipment within the scope of RTCA DO-254 standard, with its trained and expert staff and advanced technological equipment.
