I have an MTBF figure for an LRU operating in A(IC) Airborne Inhabited Cargo enviroment of 6,000 hrs. I am going to operate it in the G(M) Ground Mobile enviroment. Does anyone know the conversion factor I use to translate A(IC) to G(M)?

I went to Appendix E of the Reliability Toolkit: Commercial Practices Edition and for "Surface Mount Tech. Circuit Boards" got a conversion of 3.38. i.e. my MTBF in A(IC) was 6000 hrs in G(M) is 20280 hrs. Am I on the right track???
