System Safety
A3i Systems offers comprehensive system safety analysis services to ensure that complex electronic systems are designed to mitigate risks and meet airworthiness certification requirements. Our expertise is grounded in industry-standard practices, providing a systematic approach to identifying and managing potential hazards throughout the product lifecycle.
Our Methodology
Our safety analysis is conducted in accordance with SAE ARP4754 and SAE ARP4761, the foundational standards for modern aircraft and system development.
Preliminary System Safety Analysis (PSSA)
An early-stage analysis to identify potential hazards and determine their severity, helping to define system-level safety requirements.
System Safety Assessment (SSA)
A detailed evaluation of the final system design to confirm that it meets all safety requirements and objectives.
Functional Hazard Analysis (FHA)
Identifies the functional failures of a system and their potential effects on the aircraft, crew, and mission.
Fault Tree Analysis (FTA)
A top-down, deductive analysis that graphically represents how a specific undesirable event (a "top event") can occur as a result of a combination of component failures.
Failure Mode, Effects, and Criticality Analysis (FMECA)
A bottom-up, inductive analysis that systematically identifies all potential failure modes of each component and assesses the effects and criticality of these failures.
System-Level and Hardware-Level Safety
We also provide detailed safety analysis for hardware components, as required by DO-254.
Worst-Case Circuit Analysis (WCCA)
We analyze the performance of the circuit under the most adverse conditions (e.g., component tolerances, temperature variations) to ensure it operates reliably.
Worst-Case Timing Analysis
A critical analysis for high-speed digital designs to verify that timing constraints are met even under worst-case conditions.
Integrated Safety Approach
Our approach ensures that safety is not an afterthought but is meticulously integrated into every stage of the design and verification process, leading to certifiable and safe products.
