In this paper, we investigate the pondered selection of innovative software verification technology in the safety-critical domain and its implications. Verification tools perform analyses, testing or simulation activities. The compliance of the techniques implemented by these tools to fulfill standard-mandated objectives (i.e., to be means of compliance in the context of DO-178C and related supplements) should be explained to the certification body. It is thereby difficult for practitioners to use novel techniques, without a systematic method for arguing their appropriateness. Thus, we offer a method for arguing the appropriate application of a certain verification technique (potentially in combination with other techniques) to produce the evidence needed to satisfy certification objectives regarding fault detection and mitigation in a realistic avionics application via safety cases. We use this method for the choice of an appropriate compiler to support the development of a drone.
