This article deals with model based embedded software development of avionics systems within early fieldtrial. Realization of air-borne equipment software requirements, regulated by functional safety standards is showed. This article explains how mentioned requirements can be obtained using SCADE. The possibility of mentioned approach practical application is showed. The possibility of documentation and qualified code gene ration from SCADE Display and SCADE Suite models is showed. Use of the entioned approach allows to facili tate embedded software development and certification process for safety-critical avionics systems. Keywords: model-based design, SCADE, code generation, software certification, executable specification, verification, documentation, DO-178B.
