Our goal is to demonstrate design assurance of complex safety critical systems in compliance with regulations, in particular when using new technologies. ROSAS supports the development of aviation systems by assessing and mitigating safety critical risks in applying measures and procedures to verify safety and associated reliability and security requirements.




Functional Safety

The current shifts in commercial aviation, towards a CO2-neutral footprint with a concurrent significant increase in global mobility, require increasingly complex technologies. The identification and limitation of the associated risks require enormous efforts in order to achieve a social and technical level of acceptance, and Functional Safety Engineering methods are key to accomplish it:


In compliance with:

  • ARP 4754, ARP 4761
  • RTCA DO 178C, 254, 160, 297, 33

In addition, our aviation specialists support you in the application of the guidelines for commercial off-the-shelf (cots) digital airborne electronic hardware components, according to the guidelines made by the EASA [European Union Aviation Safety Agency] in the document "EASA Certification Memorandum", section 9 EASA-cm-swceh-001-iss01rev02, and its amendment "EASA amc 20-152 cots”.

Operational safety

The drone market will grow exponentially over the next few years, especially the number of commercial UAV (drones). This may lead to an increase in the risk of accidents caused by their operation. Therefore, in addition to the functional safety of drones, it is key to minimize risks associated with their operation.

As of January 2021, the European Union has standardized the regulations for drones, beyond the already existing SORA requirements. ROSAS, with its recognized competences, is at your disposal to support you in the evolution of these standards. 


Upcoming Cybersecurity Standards and Regulations require the consideration of cybersecurity aspects of complex and connected systems to ensure their secure operation. ROSAS supports its clients to increase the awareness and skills to cope with  industrial networks (Operational Technology) and information networks (Industrial Technology) associated threats:

  • OT Security: ISA/IEC62443, NIST800-82
  • IT Security: ISO27K series, NIST-CSF
  • Automotive Security: ISO/SAE21434, SAE J3061

Reliability and Model-Based Engineering

Because systems are becoming increasingly complex, it is becoming critical to prove their reliability. Previous practices are no longer sufficient in this respect. Model-based development, simulation-based verification, the creation of digital twins and the support of algorithms make it possible to optimize the life cycle of systems and the feedback into the system design.

The Model-Based Engineering (MBE) method, developed at ROSAS, is the ideal solution to realize this approach.
