A.3.6 System safety.
AFGS�87219B APPENDIX A
The system safety requirements for the EPS shall be as follows: ------------.
REQUIREMENT RATIONALE (A.3.6)
Safety requirements and features are needed to protect personnel and equipment.
REQUIREMENT GUIDANCE (A.3.6)
The safety requirements of MIL-STD-882 are often applied.
REQUIREMENT LESSONS LEARNED (A.3.6)
Since electrical power is now flight critical on most aircraft, a safety analysis will demonstrate that all possible failure modes are identified and appropriate design measures incorporated.
A.4.6 System safety.
Compliance with the system safety requirements of 3.6 shall be verified by analyses and tests as follows: ------------.
VERIFICATION RATIONALE (A.4.6)
Safety assessment of the electric power subsystem is an integral part of the system safety program for the total aircraft. Safety is generally verified by analytical methods which include preliminary hazard analyses, subsystem hazard analyses, and operating hazard analyses.
VERIFICATION GUIDANCE (A.4.6)
See that the appropriate safety analyses of the electric power subsystem are included in program requirements. Ensure that the requirements for the subsystem and components include appropriate tests to verify safe operation for all failure modes.
VERIFICATION LESSONS LEARNED (A.4.6)
Early safety analysis on one program discovered a major deficiency which, if not corrected, would have caused the entire electrical system to shut down in the event of two highly probable failures on one flight.
A.3.7 Interface requirements.
The EPS and its components shall interface with other aircraft subsystems as necessary to provide the performance specified herein. In addition, the following detailed interface characteristics are required: ------------.
