Dunno Wolfgang but it's a commonly quoted rule of thumb. ----
If you "dunno", why are you propogating this nonsense? Following from an earlier reply, how about a 12000lb Kingair that increases weight by 100lbs - the load factor may change in the second decimal, but NOT BY 1G. I hear what Harry Flesner says about being diplomatic and all working together, but if someone answers a legitimate question with a really misleading and wrong answer and nobody gets involved to set it straight, then what is this fantastic network achieving? It only takes one!! Thank you Stephen? for your reply. I will go with your thinking. It would be nice if the OWT guy would actually address the email with some scientific basis rather than just say "it's a commonly quoted rule of thumb" (that I never heard in 25 years). Really, really do not wish to be on the fighting side, but I must go with what I think, I joined to learn from people that know.
