I was just wondering, how do pilots calculate take off speed? Just wondering if anyone knew. I know the pricible of it, so no one come and say "They do something with the weight and somthing else" cause i know that. it would be kewl if someone could give the real calculation! Thanks in advance

Yup there is a big graph in the POH we use to get the "correct" V speeds for a given weight, temperature, flap setting, density altitude. Used to pilots figured it out manually, writing it down and doing the math, but it was all too easy to accidentally make a very small error, rotate five knots early, and stall happily into terra firma.
