Over the past 15 years, the United Kingdom UK Ministry of Defence MoD and the United States US Air Force Research LaboratoryAFRL have collaborated to develop a US-UK laser range safety tool, the Military Advanced Technology Integrated Laser hazarD AssessmentMATILDA tool. MATILDA uses Probabilistic Risk Assessment PRA techniques to perform laser safety and hazard analysis in support of airborne laser designator use during test and training exercises on military ranges. The initial MATILDA tool, MATILDA PRO Version-1.6.1,was based on the 2007 PRA model developed to perform range safety clearances for the UK Thermal Imaging Airborne Laser Designator TIALD system. The 2007 TIALD model was an approximation that assumed flat terrain on the range Smooth Earth TIALD Model, a conservative approximation valid in all terrain. Over the past five years, however, an enhanced version, MATILDA PRO Version-2.0.3, has been produced. The enhanced tool is based on an updated 2012 TIALD model, which has more complex PRA algorithms appropriate for hilly terrainRough Earth TIALD Model. For reasons of length, documentation of the mathematical algorithms and computational procedures incorporated in MATILDA PRO Version-2.0.3 has been divided between two AFRL Technical Reports. This Technical Report, designated Part I, contains documentation of the computational procedures for probabilistic faultfailure laser hazard analysis. The second Technical Report, designated Part II, will document the fault-free laser hazard analysis.
