Hey guys, i like to fly most of the time the 737, 757 and 767 also some MD80's when possible but i would like to get a little more into reality on how to calculate the climb speed on my flight plans, i usually do the fuel, heading, weight, etc etc but the climb speed i a little confused, some people say up to 3000 others say up to 3500, etc etc any help on this one please thanks.

sorry boss i think i said it wrong, im trying to get vertical climb rate, any ideas or links to read? thanks.

There are two formulas for this, one to find climb gradient as a %, and the other to find rate of climb in ft/min.(1) Climb gradient as %= ROC/TASx60/6080x100 example...1800/150x60/6080x100= 12x0.986=11.84%(2) Rate of climb in ft/min= TASx%GRADIENTx6080/60/100 example... 150x11.84x6080/60/100= 1776x1.0133=1799.68ft/minX=multiply /=divide

Both good answers which basically show there's no quick answer to your question, not if you want to get deeper into airliner simming.If you really are interested in advancing, get your self a good fmc equipped advanced airliner, dig into the docs. Years ago I found that once you go advanced, it becomes more like real world - you have to learn your current aircraft properly rather than jump in and fly anything anytime, all in the same way. Many principles you learn on one advanced aircraft help you with the next.Have fun.
