FAA AC 20-140A Integrated Modular Avionics Testing
The Federal Aviation Administration (FAA) Advisory Circular AC 20-140A sets forth the standards for testing integrated modular avionics systems used in modern aircraft. This standard ensures that these complex electronic systems meet stringent safety and performance requirements, thereby safeguarding both crew and passengers.
Integrated Modular Avionics (IMA) systems are a critical component of advanced avionics, combining multiple functions into a single platform to enhance system reliability and maintainability. However, the complexity of IMA systems necessitates thorough testing to ensure they operate correctly under various conditions. This service focuses on conducting comprehensive tests as per FAA AC 20-140A, ensuring that these systems are fit for their intended use in commercial aircraft.
The testing process involves several stages, each designed to evaluate different aspects of the avionics system. Initial testing ensures the basic functionality and compatibility of individual modules within the IMA architecture. Subsequent tests simulate operational environments, including extreme conditions such as high altitude or cold temperatures, ensuring that all components function reliably under these challenging circumstances.
One of the key challenges in testing IMA systems is their modular nature, which allows for flexible configuration based on specific aircraft needs. This flexibility, while advantageous, also complicates testing due to the variability between different configurations. Our laboratory employs advanced test methodologies and state-of-the-art instrumentation to account for these variations, ensuring that each unique system meets FAA AC 20-140A requirements.
Another critical aspect of this service is compliance with relevant international standards such as ISO/IEC 17025. Compliance verification through independent third parties ensures the reliability and accuracy of our test results.
