Our Systems Engineering services help define and validate aircraft and systems architectures. We built substantial experience in fly-by-wire flight-control systems, servo-loop design, and redundant hydraulic-electrical architectures at Airbus Helicopters. We have long practise in developing failure matrices for flight-critical and propulsion systems, including main- and tail-rotor actuation, redundant power paths, and hydraulic isolation. We have supported customers in developing power-distribution systems and propulsion-control interfaces for next-generation rotorcraft, fault containment, and system-level traceability in accordance with ARP-4754B and CS-29.1301/1309 requirements.

Through Safety & Reliability Engineering, we apply ARP-4761A methods to verify that propulsion and flight-control architectures meet CS-27/29 safety objectives. We conduct Functional Hazard Assessments (FHA), System Safety Assessments (SSA), and Common Cause Analyses (CCA) to demonstrate that all failure conditions are mitigated through redundancy, separation, and fail-safe design principles.

Our Software Development team supports the creation and verification of RTCA DO-178C / EUROCAE ED-12C compliant software for flight-control computers, engine-control systems, and vibration-monitoring units. We define development and verification plans, conduct independent audits, and can act as Software CVEs to help customers prepare for Stage-of-Involvement (SOI) reviews with certification authorities.

As rotorcraft increasingly adopt digital flight decks, data gateways, and connected maintenance systems, Product Security has become a key assurance layer. We implement EUROCAE ED-202B / RTCA DO-326A, ED-203A / DO-356A, and ED-204A / DO-355A standards to secure avionics networks and onboard data flows. Our services include Security Risk Assessments (SRA) and Plans for Security Aspects of Certification (PSecAC) aligned with EASA AMC 20-42, ensuring cybersecurity is fully integrated into the overall safety case.
