Is it Safe?: The Safety Assessment of Aircraft Systems Available to Purchase

An essential of a satisfactory safety assessment is that it should be methodical. With an elaborate system, the sheer number of possible occurrences to be considered makes a systematic approach the one with the best prospects that nothing is overlooked. The particular approach is a matter of choice. It will depend on the system to be analysed; whether it is complex or simple; whether it embodies novel or well‐established features in its design; and whether its failure affects safety in a critical way.
