AVIATION SAFETY
Do you want to put an aeronautical system on the market?
Are you developing systems or subsystems for aviation but you don't have the resources to take care of safety?
Säfeli is your partner when it comes to the safety of aeronautical systems. We can help you to guarantee the safety of your projects.
SYSTEM SAFETY ASSESSMENT
Safety is imperative in the field of aviation. Each system must meet the highest safety standards.
To achieve this, several standards can be applied to a system's development and safety.
The ARP4754 standard defines the process of developing a system and the ARP4761 standard defines the security analyses to be carried out.
FUNCTIONAL HAZARD ANALYSIS
(FHA)
Different methodologies are used to assess the risks of a system. The top-down method analyzes a system from top to bottom, gradually increasing the level of detail.
This type of analysis usually comes with a functional hazards analysis which highlights the high level functions of a system and their failures.
For each function, failure conditions and failure effects are analyzed in order to identify the severity of each failure and to propose risk reduction measures.
The maximum failure probability rates are defined there.
FAILURE MODES, EFFECTS AND CRITICALITY ANALYSIS
(FMECA)
Unlike the FHA, the failure modes, effects and criticality analysis is a bottom-up approach.
This analysis therefore begins at the component level. Each component is analyzed to define the failure modes and effects as well as the probability of occurrence.
The result of an FMECA is commonly used in a fault tree analysis, which makes it possible to link the buttom-up and top-down analyzes and thus draw conclusions on the safety of the system.
CERTIFICATION
In order to be authorized to fly, systems and devices must go through certification.
In Europe, EASA takes care of the certification.
The certification process can be long and complex, and requires providing many documents and following different processes during development.
SYSTEM RELIABILITY
No field demands greater system reliability than aviation.
Reliability is a critical characteristic of systems because safety depends on it. It is essential to ensure a certain level of reliability before the system can fly.
It starts with a clear and rigorous definition of the system specifications and its architecture.
It is also important to be able to trace and test each system specification.
