I wanted to know if anyone knew why some Jepp approach plates are different in their DH/MDA altitudes for the same airport from NACO charts. I love my jepps and it seems like when I do a sim ride for IPC purposes my instructor makes me uses his NACO charts for it. For example for CCO you have a DH or 881ft in the Jepp plates while NACO has 800ft on it (dont quote me it might be the other way around I dont have them on hand at the moment). I know its only a foot difference, however as far as whose charts are correct and how that applies to the regs. I dont want to bust altitude for having the wrong information. My Jepp charts are current per Jeppessen and its correct per the last revision. So maybe someone here has some insight.

Thanks
