I was trying gently to point out to you that your post contains a number of mistakes. Sorry that my message was not so clear. Let me make it clearer.

not C_L/C_D as you proposed. (Unless C_L is 1!!!!)
That means that your reasoning to your conclusion is mistaken (for you gave that reasoning for a generic airplane, so for example a propellor-driven one). It might be worth while for you to inquire where the mistake lies. My questions gave some hints.
