The Advisory Circular AC 20-152A, Development Assurance for Airborne Electronic Hardware, identifies the RTCA-published standard DO-254 as defining "an acceptable means, but not the only means" to secure FAA approval of complex custom micro-coded components within aircraft systems with Item Design Assurance Levels (IDAL) of A, B, or C.[1][2] Specifically excluding COTS microcontrollers,[3] complex custom micro-coded components include field programmable gate arrays (FPGA), programmable logic devices (PLD), and application-specific integrated circuits (ASIC), particularly in cases where correctness and safety can not be verified with testing alone, necessitating methodical design assurance.[4]
For DAL D hardware, as long as the applicant follows DO-254, the applicant does not need to apply this advisory circular since the FAA does not expect to examine the life cycle data.[2][5] However, if the applicant chooses to follow other design practices for DAL D hardware (as permitted by this AC) the FAA will review the data.[6]
