GM1 ATS.OR.205(b) Safety assessment and assurance of changes to the functional system ED Decision 2017/001/R SAFETY ASSESSMENT METHODS (a) The air traffic services provider can use a standard safety assessment method or it can use its own safety assessment method to assist with structuring the process. However, the application of a method is not a guarantee of the quality of the results. It is therefore not sufficient for a safety case to claim that the assurance provided is adequate due to compliance with a standard or method. (b) There are databases available that describe different safety assessment methods, tools and techniques[[38]](#_ftn38) that can be used by the air traffic services provider. The provider must ensure that the safety assessment method is adequate for the change being assessed and that the assumptions inherent in the use of the method are recognised and accommodated appropriately. --- [[38]](#_ftnref38) For example, <http://www.nlr.nl/downloads/safety-methods-database.pdf> or <http://www.scsc.org.uk/> GM1 ATS.OR.205(b) Safety assessment and assurance of changes to the functional system ED Decision 2017/001/R SAFETY ASSESSMENT METHODS (a)       The air traffic services provider can use a standard safety assessment method or it can use its own safety assessment method to assist with structuring the process.
