Lab Shows Hands-On Flight Control Testing in Rust
Raksham Labs is showcasing its hands-on testing of flight control software written in Rust. The effort highlights the raw engineering work involved in developing and validating next-generation avionics. Using modern languages like Rust is a growing trend in aerospace for its memory safety features, which are critical for building reliable systems.
Rust's strict compile-time checks for memory safety and concurrency are driving its adoption in aerospace, a domain where software errors can be catastrophic. This contrasts with languages like C and C++, which have traditionally dominated safety-critical systems but are prone to memory vulnerabilities. According to the NSA, about 70% of security issues at major tech companies are related to memory safety. The primary standard for certifying airborne software is DO-178C, which outlines rigorous processes to ensure reliability. While traditionally applied to languages like Ada, C, and C++, toolchains are now emerging to make Rust certifiable under this stringent standard. Companies like AdaCore and Ferrous Systems are developing qualified compilers and tools to bridge the gap for Rust's use in certified avionics. Historically, Ada was a leading choice for high-integrity systems, mandated by the U.S. Department of Defense for many projects and used in aircraft like the Boeing 777. However, the smaller pool of Ada developers and more expensive tooling led to a shift towards C++ and model-based development systems like Simulink. The move toward Rust in aerospace is part of a broader trend to enhance software robustness from the ground up. The language's design aims to prevent common bug classes related to memory management, which can significantly reduce testing and validation efforts. This shift is happening alongside the increasing complexity of avionics, which now often run on multi-core processors requiring careful management of shared resources.
