Abstract:(小5号黑正):This article is to address the ambiguity in the current domestic certification practice based on the DO-254 Airborne Electronic Hardware Development Assurance Guidelines regarding the board level certification strategy and objectives for circuit boards. By comparing and analyzing the relevant objectives for circuit board level in Advisory Circular AC 20-152A and Memorandum CM-SWCEH-001 regarding DO-254, and combining the certification concept of foreign airworthiness authorities and the current domestic industrial circumstance, this paper proposes considerations and suggestions for the certification strategy and methods for domestic airborne electronic hardware circuit board level.
