Complete DO-254 certification services

As a recognized leader in the development and documentation of airborne electronic hardware to each DO-254 Design Assurance Level (DAL), our services range from specification development to certification in accordance with your requirements.

Hardware planning

Experience from the successful completion of many different DO-254 developments means we are especially qualified to help you plan your electronic hardware project.

  • Determine proper DO-254 Design Assurance Level (DAL) for your project
  • Select the most appropriate silicon-based logic type (i.e. ASIC, FPGA and CPLD)
  • Specify the most appropriate development environment and toolsets
  • Develop DO-254 documents including:
    • Plan for hardware aspects of certification
    • Hardware requirements
    • Detailed design data
    • Hardware verification plan
    • Top level drawing
    • Hardware accomplishment summary
  • Provide independent design reviews
  • Prepare checklists for entry and exit criteria for all design phases and reviews

Hardware development

Our engineers are reliability experts as well as experienced hardware developers. We have been developing high-reliability electronic hardware for over 30 years and many of our projects have been developed in compliance with DO-254 since its release. Areas of expertise include:

  • Requirements development, analysis and allocation
  • High-and low-level design capture
  • Design standards development
  • Parts selection criteria
  • EMI design for MIL-STD-461 and DO-160
  • Printed circuit design for minimal space and severe environments
  • Reliability, Maintainability, and Testability
  • Thermal analyses
  • Peer reviews with meaningful results
  • Unit test design
  • Bring-alive and bench testing

Hardware test and verification

Developing efficient test plans and procedures to streamline testing while assuring that tests correctly and completely verify requirements in the least amount of time, we develop automatic test equipment geared towards lab testing, first article testing, production testing and any other testing needs.

  • Integration planning
  • Comprehensive testing to requirements
  • Qualification plans and procedures with full requirements traceability
  • Verification coverage analysis
  • Remediation plans
  • Test reports

Reliability Analysis Techniques: How they Relate to Aircraft Certification

What’s Inside: Classic reliability analysis techniques, namely, Reliability Prediction, Fault Tree Analysis (FTA) and Failure Mode Effect Analysis (FMEA) are the framework for the aircraft certification process. These innovative technique have been utilized since the 1990s with the advent of the Society of Automotive Engineer’s Aerospace Recommended Practice 4761 (SAE ARP 4761). Today, SAE ARP 4761 is the defacto standard used for aircraft certification.
