Slide 18

CTA ( CENTRO TCNICO AEROESPACIAL) BRAZILIAN AERONAUTICAL CERTIFICATION DIVISION SYSTEM SAFETY ASSESSMENT PROCESS 18 GERENCIAMENTO DA SEGURANA (Safety Management) The goals of system safety can be achieved only with the support of management: A sincere commitment to safety by management is perhaps the most important factor in achieving it. An example of how this results was accomplished was the B-1B program, in which the Program Manager or Deputy Manager chaired the meetings of the group where safety decisions were made. An Air Force study of system safety concluded: Air Force top management support of system safety has not gone unnoticed by contractors (...)
