 This tutorial covers the SAE ARP4761 approach to system safety assessment. 
  
 Topics covered include Functional Hazard Assessment (FHA), Preliminary 
 System Safety Assessment (PSSA), System Safety Assessment (SSA), and Common 
 Cause Analysis (CCA), and Development Assurance Levels (DALs). 
  
 System safety is a key element of airworthiness.  For this reason, when we 
 think of system safety, we think of safety relative to flying the aircraft. 
 There are other types of safety though.  There is safety as it applies to 
 the crew and passengers, there is safety as it applies to maintaining the 
 aircraft, there is safety as it applies to the environment, and there is 
 safety as it pertains to health hazards.  These additional aspects of safety 
 assessment are discussed as well.
