ARP-4761A:
Safety Assessment Process Training

A Holistic Approach to System Development and Safety Processes

COURSE DEFINITION

System and Safety Integration

ARP-4761A are the two foundational guidance documents in civil aviation that define the synergy between system development and safety activities. While ARP-4754B establishes the aircraft and system life cycle and development assurance framework, ARP-4761A provides the methods for safety analyses necessary to guide this process.

BRNAvionics delivers this integrated training to demonstrate how system engineering and safety assessments function as a unified discipline rather than isolated tasks.

Training Objectives
Master Development & Safety Fundamentals

Gain a profound understanding of how aircraft and system development assurance (ARP-4754B) is driven by safety assessment processes (ARP-4761A).

Integrated Process Execution

Learn to conduct system and safety activities as parts of a cohesive whole, ensuring that safety outputs directly influence architecture and design decisions.

Analyze Safety-Driven Impact

Evaluate how safety justifications (FHA, PSSA, SSA, FTA, FMEA) determine the certification path and ensure robust regulatory compliance at both the aircraft and system levels.

Establish Traceable Justification

Acquire the expertise to flow down safety requirements into verifiable system specifications, creating a seamless link between safety and engineering.

Process Implementation and Management

Develop the skills to establish an auditable development process where safety evidence provides the primary justification for system-level decisions.

Our training programs are delivered exclusively as in-company sessions.

Development Assurance and Safety Relationship

Safety analyses are the primary decision mechanisms that guide the system life cycle.

FHA

Functional Hazard Assessment and definition of system limits.

PSSA

Preliminary System Safety Assessment and architectural guidance.

SSA

System Safety Assessment and final safety justification.

Safety in System Analysis and Design Processes

Direct impact of safety analyses on engineering decisions.

Functional Analysis and FHA

Relationship between function definitions and FHA studies, and the impact of hazard classifications on DAL allocation.

Architectural Decisions and PSSA

Relationship between redundancy, segregation, and fail-safe principles with safety justification.

Requirement Derivation and DAL

Alignment of requirements derived from safety goals and DAL allocation with system architecture.

Verification and Audit Perspective

The role of Validation and Verification activities as safety evidence.

Validation & Verification

System-level verification activities supporting safety justification and providing input for the SSA phase.

Safety Evidence

Audit and Implementation

Joint evaluation of system and safety processes in audits and the ability to create defensible responses.

Audit Readiness

Training Methodology and Deliverables

The training is conducted through real project scenarios and application examples rather than a verbatim delivery of standard clauses. The applicability of topics to the project is strengthened with discussions that encourage system and safety teams to work together.

Key Outcomes

  • Holistic interpretation of system and safety processes
  • Justifying DAL allocation
  • System-safety consistency in the certification process

Duration and Format

Training Duration: 3 Days

Format: In-house, classroom, or online options.

Language: Turkish and English options available.

Training Participation Certificate

Consultancy, CVE, and Process Assurance Services

Holistic certification management support in safety-critical aviation projects.

Certification Consultancy

Our certification consultancy service aims to structure projects correctly from the start and minimize certification risks in later stages. In this context, consultancy includes not just document review, but guidance on strategy, process, and technical decisions. By creating an applicable and sustainable certification roadmap, it becomes a natural part of the development process.

Compliance Verification Engineer (CVE) Role

The Compliance Verification Engineer (CVE) is a critical role that ensures independence, objectivity, and traceability in the certification process. The CVE is a technical and methodological assurance mechanism that verifies whether the developed system, processes, and output truly comply with the relevant standards. Our firm takes on the CVE role in projects, systematically evaluating the compliance of system, safety, software, and hardware outputs with standards.

Process Assurance Services
Process assurance is an important activity that ensures aviation development processes comply with standards and are kept under constant control. Our firm provides independent and objective process assurance services to ensure your development processes are implemented as planned and risks related to processes are identified and resolved in a timely manner.

Why BRNAvionics?

Our firm has been actively involved in aviation and safety-critical system projects for 4+ years, providing certification consultancy, CVE, and process assurance services to its domestic and international clients. By combining theoretical knowledge with field experience, we aim to provide our clients not just with “compliance” but with an auditable, sustainable, and reliable certification infrastructure.

Are You Ready for Certification?

BRNAvionics training doesn’t just explain standards; it provides actionable, defensible knowledge for real projects.
