Does Al HEAF Require a Change to Modeled ZOI?
It is a safety concern warranting action It is not a safety concern
- OECD non-prototypic test but no ZOI
- Cables very robust measured
- 100,000s of component operating years with Al widespread
- No op ex shows an increased ZOI
- Harris HEAF with Al
- Actual ZOI bounded by modeled ZOI
- Cables in ZOI functional
- Robinson within modeled ZOI
- Appendix R separation - change in ZOI would have to be ve r y l a rge
