S.A.F.E. SOLUTIONS

Module Fonction

This module allows to manage the Aircraft and System Functions

Process:

Aircraft and System Functions are inputs for the AFHA and the SFHA.
One the Functional Safety Analysis will be completed, two types of requirements can be allocated to the Functions :

Functional Independence Requirements
FDAL Requirements

Class of Data	Definition
Aircraft / System Function	Intended behavior of an aircraft or system regardless of implementation.
Functional Independence Requirement	Requirement related to a characteristic that minimizes the likelihood of common development error by using different functions.
FDAL Requirement	Requirement related to the level of rigor of development assurance tasks performed to Functions.

Main Features:

List, View, Edit, Duplicate, Delete the Aircraft and System Functions, the FDAL Requirements and the Functional Independence Requirements.
Determine if some functions could be excluded from the Safety Analysis, and provide a rationale
Provide an overview of each function (see the first picture), which provides the number of associated :
- Functional Failure Mode
- Aircraft Functional Scenarios – Failure Conditions
- FDAL Requirements
- Independence Requirements
- System Contributors
- Sub-functions
Manage the contribution of the systems to each function and provide a matrix Functions vs Systems (see picture above).
Compare the FDAL currently required and the FDAL calculated from the Safety Analysis.
