SAM Toolkit
The EUROCONTROL Safety Assessment Methodology (SAM) is a framework, a toolbox containing methods and techniques to carry out safety assessment of changes to the functional systems of the Air Navigation Service Providers (ANSP). It was developed in the noughties of the 21st century as means of compliance to ESSAR 4.
The objective of the methodology is to support the provision of assurance of the safety of the Air Traffic Services (ATS) provided by an ANSP. It covers the entire system/change life cycle: specification, design, implementation, integration, transfer into operation and operation and maintenance. The assessment process includes Functional Hazard Assessment (FHA), Preliminary System Safety Assessment (PSSA) and a System Safety Assessment (SSA).
SAM is organised in three levels: level 1 explains the "what", level 2 provides details on "how" to perform a safety assessment and level 3 provides real life examples from ANSPs and the industry.
Although there have been many changes in the regulatory framework in Europe and elsewhere, SAM is still relevant and can be used for risk assessment and mitigation purposes.

PSSA V2-1 INTRO – Introduction
PSSA V2-1 INTRO – Introduction
This document introduces the objectives of a Preliminary System Safety Assessment (PSSA) as well as the various steps which constitute the PSSA. These steps are described in subsequent documents. The main objective of the PSSA is to demonstrate whether the assessed system architecture can reasonably be expected to achieve the Safety Objectives specified in the FHA.
PSSA V2-0 Chapter 1 – Initiation
PSSA V2-0 Chapter 1 – Initiation
The objectives of the PSSA Initiation step are to develop a level of understanding of the system design and its rationale, to update the description of the operational environment and, when appropriate, to identify the regulatory requirements and/or standards applicable to the system design.
PSSA V2-0 Chapter 2 – Safety planning
PSSA V2-0 Chapter 2 – Safety planning
The objective of the PSSA Planning step is to the define objectives and scope of the PSSA, the activities to be carried out, their deliverables, their schedule and the required resources.
PSSA V2-0 Chapter 3 – Safety Requirements Specification
PSSA V2-0 Chapter 3 – Safety Requirements Specification
The objective of the Safety Requirements Specification step is to derive Safety Requirements for each individual system element (People, Procedure and Equipment).
PSSA V2-0 Chapter 4 – Evaluation
PSSA V2-0 Chapter 4 – Evaluation
The objective of the PSSA Evaluation is to demonstrate that the PSSA process meets its overall objectives and requirements. The Evaluation is carried out in three stages: Verification, Validation and Process Assurance.
PSSA V2-0 Chapter 5 – Completion
PSSA V2-0 Chapter 5 – Completion
The objectives of the PSSA Completion step are the following: recording of the results after the completion of the PSSA process and dissemination of these results to all interested parties.

PSSA V2-0 Chapter 1 GUIDANCE A – Operational Environment Definition
PSSA V2-0 Chapter 1 GUIDANCE A – Operational Environment Definition
This guidance material helps further describing the Operational Environment so that PSSA can be performed. The OED was already made during FHA, however some data have to be further detailed for the system design phase and its safety assessment (PSSA).
PSSA V2-0 Chapter 2 GUIDANCE A – Planning PSSA Activities
PSSA V2-0 Chapter 2 GUIDANCE A – Planning PSSA Activities
This guidance material provides guidance on how to plan PSSA activities. These recommendations aim at completing the part of the safety plan dealing with PSSA.
PSSA V2-1 Chapter 3 GUIDANCE A – Safety Requirements
PSSA V2-1 Chapter 3 GUIDANCE A – Safety Requirements
This guidance material provides guidance on the definition, content, phrasing, criteria of eligibility of safety requirements. It also includes the process to allocate Assurance Levels (Procedure: PAL and Software: SWAL).
PSSA V2-1 Chapter 3 GUIDANCE B – Automation
PSSA V2-1 Chapter 3 GUIDANCE B – Automation
This guidance material provides recommendations on how to address automation especially when looking at its influence on the design and its safety-related aspects.
PSSA V2-1 Chapter 3 GUIDANCE C – Sensitivity Analysis
PSSA V2-1 Chapter 3 GUIDANCE C – Sensitivity Analysis
This guidance material provides guidance for applying sensitivity analysis technique as part of the PSSA.
PSSA V2-1 Chapter 4 GUIDANCE A-B-C – PSSA Evaluation Activities
PSSA V2-1 Chapter 4 GUIDANCE A-B-C – PSSA Evaluation Activities
This guidance material provides practical guidance on verifying and validating a Preliminary System Safety Assessment (PSSA). The objective of these guidelines is to ensure that the PSSA is suitable for use during the System Safety Assessment (SSA).
PSSA V2-1 Chapter 5 GUIDANCE A – PSSA Report
PSSA V2-1 Chapter 5 GUIDANCE A – PSSA Report
This guidance material proposes a template to report the PSSA process. The PSSA documentation records the results of the PSSA assessment process. This document will be updated through the complete system life cycle.
