At the table 10.3-6 in MIL-HDBK-338B, there are 1A to 1F models of Rf selection category for Airborne Inhabited Fighter Models. How can I choose the right model? What does the character(A,B.. F) mean?
I would be grateful if you answer question as soon as possible.
Operational Translation Models 1A through 1F in Table 10.3-6 of MIL-HDBK-338B pertain to the Airborne, Fighter environment. Models 1A through 1F differ from each other with regard to the parameter to be calculated (MTBFF, MTBMF and MTBRF) and the model inputs available (θD vs. θP), the combination of which should guide model selection. For example, if estimation of the fielded MTBR (MTBRF) is desired and an MTBF that has been demonstrated during a controlled test (θD) is known, then model 1F should be selected. Definitions of the various parameters can be found in section 10.3.2.1 of MIL-HDBK-338B.
