You should be fine with one alt/mach pair. I did not find any significant differences in the coefficients when running on more than one pair and playing with the LOOP. > > In the BODY section, will it use ZU and ZL to calculate the area if I > give it R, or do I need to specify S to get good area rule calculations? The user manual says for S, P and R: "Only one variable is required. If one variable is input the other two are computed from it, assuming a circular cross-section" (Page 34 of the pdf) So using ZU, ZL and R should be ok if your (the aircraft's) body is anything like a tube and the cross section is more or less circular.
Do you have a copy of the USAF_DATCOM_UM.pdf? It's on Bill's page http://www.holycows.net/datcom/ This is a lot to read but you will find many answers in there. > More questions to follow ... looking forward...
