1.6 System Safety Objectives
This handbook supports the achievement of the following system safety objectives:
· Safety, consistent with mission requirements, is designed into the system in a timely,
cost-effective manner.
· Hazards associated with the system (and its component subsystems) are identified,
tracked, evaluated, and eliminated, or the associated risk is reduced to a level
acceptable to FAA management throughout the entire life cycle of a system. Risk is
described in Comparative Safety Assessment terms. See Chapter 3.
· The safety design order of precedence is applied and FAA management accepts the
residual risk.
· Safety analyses and assessments are performed in support of the FAA safety risk
management efforts and are in accordance with the best safety engineering practices.
· Historical safety data, including lessons learned from other systems, are considered
and used in safety assessments and analyses.
· Minimum risk is sought in accepting and using new technology, materials, or designs:
and new production, test and operational techniques in the NAS.
· Retrofit actions required to improve safety are minimized though the timely inclusion
of safety features during research, technology development, and acquisition of a
system.
· Changes in design, configuration, or mission requirements are accomplished in a
manner that maintains a risk level acceptable to FAA management.
· Consideration is given early in the life cycle to system safety through the end of the life
cycle which includes system decommissioning.
· Significant safety data are documented as “lessons learned” and are submitted to data
banks or as proposed changes to applicable design handbooks and specifications.
1.7 Glossary
Appendix A contains a glossary of terms that are used throughout the handbook. It is important to
understand the difference between a hazard and a risk, for example, and how these terms relate to
the system safety methods. The glossary also provides discussion on different definitions
associated with specific system safety terminology. It is important to understand the different
definitions. The glossary can be used as a reference, i.e., as a dictionary. Many terms and
definitions associated with system safety are included. The glossary can be used for training and

educational purposes. Depending on the need, these terms and definitions can be used when
discussing methodology or when conducting presentations. There are terms referenced that are not
specifically addressed in the handbook. These additional terms are important, however, as
reference material.
