The UK Civil Aviation Authority (CAA) has issued ORS9 No. 50, adopting the latest Certification Specifications (CS) for large rotorcraft (CS‑29), engines (CS‑E), and airborne communications, navigation, and surveillance systems (CS‑ACNS). These specifications provide updated technical benchmarks for the design and approval of helicopters and related systems, with direct relevance to operators in demanding sectors such as offshore oil and gas. While non-binding, the new standards serve as acceptable means of compliance for aircraft certification in the UK, supporting innovation, safety enhancements, and regulatory alignment.
