DO-254 Hardware Development & Certification
DO-254 Design Assurance Guidance for Airborne Electronic Hardware Certification
For nearly a decade, CERTON has provided services and solutions to customers across the board in the Aerospace industry. From Commercial Aviation to Space Flight, CERTON is focused on certification of Airborne Electronic Hardware (AEH) compliant with RTCA/DO-254 Design Assurance Guidance for AEH certification guidelines. CERTON can work closely with your company to ensure successful TSO and/or Type Certification during any phase of your project that includes safety-critical electronic hardware development utilizing the DO-254 standard.
DO-254 Design Assurance Level (DAL)
For systems and equipment using electronic hardware to fulfill a safety related aircraft function, the FAA cites RTCA/DO-254 as a means of compliance to the Federal Aviation Regulations (FARs) Part 21, 23, 25, 27, 29 and 33. The FAA defines RTCA/DO-254 as a means, but not the only means, of compliance to the FARs. It is an extremely rare exception that an alternative means of compliance is used for electronic hardware in avionics applications.
In order to certify safety-critical airborne electronic hardware using the RTCA/DO-254 guidelines, the system safety assessment process will identify the applicable DAL according to the five failure conditions categories necessary for safe operation identified in the table below.
|Design Assurance Level||Condition|
|Electronic hardware that would cause or contribute to a failure of the system function resulting in conditions that would prevent continued safe flight and landing.|
|Electronic hardware that would cause or contribute to a failure of the system function resulting in reducing the capability of the aircraft or the ability to the crew to cope with adverse operating conditions so that there would be a large reduction in safety margins of functional capabilities.|
|Electronic hardware that would cause or contribute to a failure of the system function resulting in reducing the capability of the aircraft or crew with adverse operating conditions that would create a significant reduction in safety margins or functional capabilities, a significant increase in crew workload, possibly including injuries.|
