Aerospace - Reliability and System Safety Assessment
BE Analytic’s Reliability and Safety Engineering team improves and maintains the safety and reliability of products throughout the development life cycle. Once a product is in service they assess safety and reliability issues and help identify potential solutions, communicating with Design/System Engineers to find the optimal balance between reliability and performance. BE Analytic successfully handled increasingly stringent legislation, and more demanding customers. Our Reliability Engineers are well-read in different Aero and Defense Standards.
BE Analytic is involved with the Design and development team/Systems Engineering Team and ensures that your products will meet all the Reliability and safety compliance, BE Analytic executes routine tasks like performing.

System Safety Assessment (SSA)
System Safety Assessment is a structured analytical process used to show that an aircraft system design satisfies its safety objectives. We perform the complete SSA workflow as defined in SAE ARP4761, which forms the safety assessment backbone of civil aviation certification programs under CS-25, FAR 25, and equivalent regulations.
Functional Hazard Assessment (FHA)
FHA identifies the potential failure conditions associated with each aircraft-level and system-level function, and classifies them by severity (Catastrophic, Hazardous, Major, Minor, No Safety Effect). FHA establishes the top-level safety objectives that all downstream analyses must satisfy.
Preliminary System Safety Assessment (PSSA)
PSSA evaluates proposed system architectures against the safety objectives established in the FHA. Using Fault Tree Analysis (FTA) and Dependency Diagrams (DD), we verify that the architecture provides sufficient redundancy and independence to meet quantitative safety targets before detailed design begins.
Fault Tree Analysis (FTA) and Markov Analysis
We construct fault trees to quantify the probability of top-level failure events and identify critical cut sets. For systems with repairable redundancy or complex state transitions (such as flight control systems or power distribution networks), we apply Markov modelling to capture time-dependent failure and repair behaviour.
Common Cause Analysis (CCA), Zonal Safety Analysis (ZSA), and Particular Risk Analysis (PRA)
Independence and separation are fundamental principles of aerospace safety design. Our Common Cause Analysis verifies that redundant system elements are not susceptible to common failure mechanisms. Zonal Safety Analysis examines physical installation zones for unintended interactions between systems. Particular Risk Analysis evaluates threats such as fire, bird strike, high-energy rotor burst, and lightning.

Frequently Asked Questions About BE Analytics Aerospace Services
Everything you need to know about Aerospace reliability and safety analysis services.
FHA is a top-down analysis that identifies hazards associated with the loss or malfunction of system functions. FMEA is a bottom-up analysis that identifies how individual components can fail and what effects those failures have on the system. Both are required for a complete System Safety Assessment — FHA defines the safety targets, and FMEA helps verify the design meets them.
We support the reliability and safety assessment aspects that interface with DO-178C, including deriving software safety requirements from the system-level FHA and FTA. For the software development assurance process itself, we collaborate with your software team or their designated DO-178C partner.
We use MIL-HDBK-217 for standard parts-count and parts-stress predictions, FIDES for mission-profile-based predictions, and Physics of Failure for critical components where empirical data or accelerated test results provide a more accurate reliability estimate than handbook methods.
DAL is for avionics per DO-178C/DO-254 and rates software/hardware development rigor A-E. SIL is from IEC 61508 and rates risk reduction levels 1-4 for safety systems. Aerospace uses DAL for airborne systems, while SIL applies to ground systems and cross-industry safety standards.
