As a leading engineering and certification services company in the aerospace market, ConsuNova has built expertise and resources to support RMS Engineering function.

Through investment in personnel, resources and robust processes ConsuNova, Inc. has created unique solutions and services supporting all aspects of Safety Engineering.

The aircraft System Safety Assessment (SSA) is a vital foundation for EASA / FAA Certification. The role of the safety assessment is to ensure the safety of the aircraft, its crew, and the occupants. Essentially, aircraft safety is ensured by performing careful in-depth quantitative analysis, architectural optimization, criticality level function determination identification, highly reliable components, adequate analysis-driven redundancy of functions and items. Defining and monitoring adequate Design Assurance Levels (DAL) via worst-case functional Hazards and sound maintenance practices.

ConsuNova brings a safety assessment process utilizing experienced engineers to proceed through a series of analysis pertaining to the system and aircraft. As the safety assessment proceeds, the following documentation is developed:

  •         Functional Hazard Assessment (FHA)
  •     Fault Tree Analyses (FTAs)
  •     Common Mode Analysis (CMA)
  •     Common Cause Analysis (CCA)
  •     Failure Modes, Effects & Criticality Analyses (FMECAs)
  •     Design Assurance Level (DAL) Determination

Market response and demand has exceeded expectations. Adds Mort Leith, Senior Safety & Reliability Advisor, “We are able to ‘Tailor’ your safety analysis efforts in accordance with your Customer Requirements, eliminating the unnecessary cost of analyses that is not required. This potentially yields an approximate savings of 20-30% as opposed to performing the entire spectrum of RMS analyses that most Aerospace or Aircraft companies end up generating.”

ConsuNova’s Safety Team can demonstrate how your design and the associated Plan for Hardware Aspects of Certification (PHAC) along with the Complex Electronic Hardware (CEH) per DO-254, is derived using the System Safety Analysis. Particularly the Severity of the worst-case Hazards (Functional Failure Conditions) of the Functional Hazards Analysis (FHA) being the area that drives the Functional DALs (FDALs) and Item Design Assurance Levels (IDALs) of the Programmable Devices per SAE ARP 4754A, as well as the DALs of the Software per DO-178C or DO-278A.

“We also specialize in identifying Critical Functions via a Failure Modes, Effects & Criticality Analysis (FMECA). We use this analysis to isolate Built-in-Test (BIT) and Redundancy Requirements eliminating the possibility of Over-Designing via unneeded Redundancy or BIT Monitoring/Detection, which severely adds to Design Cost.”; says Reza Madjidi, ConsuNova’s President and Software DER.

ConsuNova safety experts excel at Safety Mentoring, Active Workshops and SAE ARP 4761 Training to help raise the knowledge level of any existing RMS Engineers.
