SYSTEM ENGINEERING

S-PLANE prides itself on the effective use of system engineering as a structured and reliable means to the desired end. We are active participants in the International Council on System Engineering (INCOSE) and subscribe to the system engineering principles advocated. Planning, process definition, requirements capture, structured design, interface definition, risk assessment, verification, validation, qualification, tracing and configuration management are all key system engineering elements performed by S-PLANE across system, subsystem, software and hardware levels.

System level developments are typically guided by Aerospace Recommended Practice (ARP) guidelines ARP-4752A and ARP-4761, describing certification considerations for highly integrated and complex aircraft systems and the associated safety assessment processes.

Software developments are guided by RTCA DO-178C and its supporting supplements DO-331 through DO-333 for model based design, object oriented programming and formal methods use. S-PLANE strongly supports the use of qualified verification tools, developed according to DO-330 guidelines, to reduce development and verification life cycle costs and ultimately ensure higher levels of system safety.

RTCA DO-254 is used as a guideline for S-PLANE’s hardware development processes. Hardware is environmentally qualified and stress screened in accordance with appropriate military and aviation standards including MIL-STD-810G, MIL-STD-461F and DO-160G.
