RAAML12 — Add Functional Hazard Assessment (FHA) method to RAAML

RAAML contains the ISO 26262 method to support the analysis and requirement specification aspects of Functional Safety. However, ISO 26262 focuses on the automotive industry. To also cover the aerospace sector, the Functional Hazard Assessment (FHA) method according to ARP 4761A should be brought as a method to RAAML and should be properly linked to Core, General, FMEA and ISO 26262 packages.

Define and propose modifications to RAAML 1.2 to include Functional Hazard Assessment (FHA) method.

Minor changes in front matter (chapters 1 through 6), add a new section on FHA in chapter 9 (profile and library), add a new section on FHA in chapter 10 (Views), and addition of subsection to examples document. See the attached .docx files for content of these new sections.
The Functional Hazard Assessment (FHA), as described in the ARP 4761A, is a systematic, comprehensive evaluation of the functional decomposition of a system or platform, performed at early stages of the V development process. This assessment identifies and classifies the failure conditions associated with each function. The goal in conducting an FHA is to clearly identify each failure condition along with the rationale for its severity classification. The classification of these failure conditions establishes the safety objectives to be met.
