ARP 4761
Ensuring Aircraft Safety
ARP 4761 is a crucial guideline for conducting safety assessments on civil airborne systems and introduces the concept of Aircraft Level Safety Assessment, offering systematic approaches to comply with safety requirements. It is applicable to both new designs and modifications. It also guides in meeting the aircraft certification requirements set by aviation authorities.
However, Implementing ARP 4761 can be challenging due to the extensive safety assessment tools required and the complexity of modern aircraft systems. Errors in the design phase, often unnoticed until later stages, require skilled professionals to identify and address problems promptly during the product's lifecycle.
We perform Preliminary Aircraft Safety Assessment (PASA), Aircraft Functional Hazard Analysis (AFHA) to define safety requirements
Aircraft Level
We conduct SFHA and Preliminary System Safety Assessment (PSSA) to to validate safety requirements, develop Built-in-Tests (BITs) and Pre-flight Manuals
System Level
We support in software and hardware design and certification, adhering to RTCA/DO-178 and RTCA/DO 254
Design Analysis
We are experts in safety tools such as Fault Tree Analysis (FTAs), FMEAs, Dependence Diagram (DD), Markov Analysis (MA) and proficient in lifecycle management software such as Polarion and DOORS
Safety Tools
We provide comprehensive safety assessment by conducting Common Cause Analysis (CCAs), Particular Risk Analysis (PRA), Common Mode Analysis (CMA) and Zonal Safety Analysis (ZSA), along with support for liaising with certifying bodies
Supporting Activities
In accordance with AR4761, we validate that the right system is built and verify that it is built correctly
