LDRA has introduced a comprehensive DO-178C ecosystem of compliance management tools, following the Federal Aviation Administration officially recognising DO-178C and its supplements as a means of compliance for avionics software development. With continued executive-level involvement in the formation of industry standards, LDRA has extended its DO-178B/ED-12B expertise to include the new guidance of both U.S. and European standards within the LDRA tool suite and DO-330-compliant tool qualification packs.

The new DO-178C/ED-12C standard clarifies guidance to remove ambiguities in DO-178B and enforce the safest software development practices. DO-178C/ED-12C now advises that companies provide:

Data and control coupling analysis where predicted system behaviour is metrically compared to actual system behaviour up to Level A where object code is examined.
Object code verification to ensure that no additional code has introduced errant or unexpected behaviour in the machine code and that all code has been tested.
Trace data analysis to show that requirements are linked to all software artefacts to prove fulfilment of each requirement at the design, code, and test stages of development.
Conformance to software coding standards to show consistency and quality of source code.
Verification of model-generated code and systems to provide independent analysis of the generated code at the model and target system.
Automated verification of Object-Oriented Technology subclasses to ensure local type consistency is met.
Compliance management for a fully compliant infrastructure and documented system development.

LDRA is uniquely qualified to meet these objectives, having adopted many of these competencies already. The LDRA tool suite is qualifiable for Level A compliance and the LDRA Compliance Management System is widely used by avionics OEMs, avionics suppliers, military equipment suppliers, and the FAA. LCMS provides a fully compliant infrastructure based on best practices from industry (clients and RTCA committees) and authorities (FAA, EASA, military in many countries). Guiding LDRA’s certification process are Designated Engineering Representatives, fully approved by the FAA and EASA.

“LDRA has been instrumental in the compliance and certification of more than 150 avionics systems worldwide, many of them to the highest FAA and EASA qualification standards. In working toward software with zero defects, our tools have long offered independent model verification, checked object code for any additional code, linked requirements to code and tests, and delivered full compliance management through LCMS—all features now required by the new avionics standards. We are proud to immediately deliver the broadest range of critical DO-178C/ED-12C capabilities in the market,” comments Ian Hennell, LDRA Operations Director.
