DO-178 Training | DO-178C Training | DO-254 Training by Tonex

The two government documents, DO-178 and DO-254, define compliance specifications for airborne systems, while DO-178C improves terminology over the 178B as well as to ensure all standards are up-to-date with modern electromechanical systems and best practices.

The 178C standard provides recommendations for the production of airborne systems and equipment software. Compliance with the objectives of DO-178C is the primary means for meeting airworthiness requirements and obtaining approval of software used in civil aviation products.

The overall DO-178C guidance consists of six key areas: planning, development, verification, configuration management, quality assurance and certification liaison.

Testing forms a part – but not the whole – of verification. While testing follows development in the software life cycle, verification is really a concurrent process that carries on throughout.

The DO-254 document classifies electronic hardware items into simple or complex categories.

An item is simple if a comprehensive combination of deterministic tests and analyses appropriate to the design assurance level can ensure correct functional performance under all foreseeable operating conditions with no anomalous behavior.

But a complex item is one that cannot have correct functional performance ensured by tests and analyses alone; so, assurance must be accomplished by additional means.

The body of DO-254 establishes objectives and activities for the systematic design assurance of complex electronic hardware, generally presumed to be complex custom micro-coded components.

The DO-178 and DO-254 standards presume that hardware and software must operate in harmonic unison, each with proven reliability. Previously, hardware was tested at the system level with integrated software and considered exempt from DO-178 quality attributes.

But that exemption resulted in functionality being moved from software to hardware for the purpose of avoiding software certification. Also, hardware complexity has evolved such that hardware is often as complex, or more so, than software due to the embedded logic within PLDs, ASICs, and FPGAs.

DO-178 Training Course, Aviation Certification

DO-178 Training, DO-178C training course and DO-254 Training Course is a combined program focusing on Avionic Certification.

TONEX DO-178 Training, introduction to Avionics Certification covers all the aspects of DO-178B, DO-178C, DO-254.

Learn the best practices to achieve DO-178C and DO-254 compliance when it comes to certification of avionics systems: real-time embedded applications, graphics and displays, simulation, flight and engine control systems, power, actuation, mechanical and electro-mechanical systems, navigation and communication systems.

DO-178C Training Course provides the grounds for the production of software for airborne systems and equipment that performs its intended function with a level of confidence in safety that complies with airworthiness requirements. Achieve compliance with the objectives of DO-178C is the primary means of obtaining approval of software used in civil aviation products.
