[QUOTE="Mikecr, post: 1203080, member: 1521"] Use of the formula seems out of whatever context it was in. If you already know the form factors(derived from individual drag components combined & compared to G7 standard per mach#), you already know the BCs (simple sectional density divided by the known form factor). The problem you end up with here is figuring out or testing to determine form factor. In no way could this be assumed, as it's weak enough in prediction. If Bryan hadn't done it for you -then you would have to do it yourself (good luck with that). In other words, forget rules of thumb for BC. [/QUOTE]
