DO330

DO330 is a certification requirement established by the European Union Aviation Safety Agency (EASA). It specifically addresses the development assurance of software for aircraft systems. The objective of DO330 is to ensure that software used in aviation is safe, reliable, and meets stringent quality standards throughout its lifecycle. This includes processes for software design, implementation, testing, and maintenance.

The document, officially titled "Software Considerations in Airborne Systems and Equipment Certification," provides guidance on the methods and tools that developers must employ. It emphasizes a structured approach to software development, encouraging rigorous verification and validation activities. This helps to identify and mitigate potential software-related hazards that could compromise flight safety.

DO330 is not a standalone standard but is typically applied in conjunction with other aviation safety regulations and standards, such as those set by the Federal Aviation Administration (FAA) in the United States. Compliance with DO330 is a critical step for manufacturers seeking to certify aircraft that incorporate complex electronic or software-based systems. The standard aims to provide a clear framework for achieving the necessary level of assurance for airborne software.
