Specifically, at their Toulouse facility, Airbus has integrated CompCert into several projects, although the exact details of these projects remain undisclosed. https://www.absint.com/compcert/index.htm The decision to adopt CompCert was driven by a need to enhance performance, particularly by reducing the Worst-Case Execution Time (WCET) of their software. A feasibility study conducted between 2012 and 2013 demonstrated that using CompCert led to a 12% improvement in WCET, surpassing their initial target of 11%. https://projects.laas.fr/IFSE/FMF/J3/slides/P05_Jean_Souyiris.pdf By utilizing CompCert, Airbus benefits from the compiler's formal verification, which mathematically ensures that the compiled code preserves the semantics of the source code.
