Prove Your Plane Now!

The DO-333 is now available! (ok, that’s not free: 215$ for an electronic version, or 300$ for a hard copy, pfew!)

Under this amazingly explicit name is hiding the formal methods supplement for DO-178C. Or, said otherwise, the document that allows you, as a developer of avionics software, to replace tests/reviews/analyses by formal methods. Or you, as a provider of techniques and tools for formal methods, to find customers in the avionics market. Ah yes, because the new version of the certification standard for avionics software, DO-178C, has been also issued at the same time. So that starts today!

Here is what the abstract of this doc says:

This supplement identifies the additions, modifications and substitutions to DO-178C and DO-278A objectives when formal methods are used as part of a software life cycle, and the additional guidance required. It discusses those aspects of airworthiness certification that pertain to the production of software, using formal methods for systems approved using DO-178C.

Formal methods are mathematically-based techniques for the specification, development and verification of software aspects of digital systems. The mathematical basis of formal methods consists of formal logic, discrete mathematics and computer-readable languages. The use of formal methods is motivated by the expectation that, as in other engineering disciplines, performing appropriate mathematical analyses can contribute to establishing the correctness and robustness of a design.
