So there are a couple of options to consider.
The first is migrating the question from Aviation to Engineering. As your question has already been favorably received on Aviation and attracted a reasonable answer, it's pretty unlikely that the Aviation moderators would agree to migrate your question.
The second is re-posting your question as-is from Aviation here on Engineering. This is also called cross-posting a question. For a number of reasons, SE strongly discourages cross-posting. So please don't just re-post your question.
The third option is to ask a new question, and is likely the option you want. This is where you take the existing Aviation question and re-work it so that it's directly applicable to the site you want to ask it on. Asking a new question can use another question as supporting information, but the new question ought to be easily discernible from the existing one.
You didn't say what you have a question about regarding the original question you asked on Aviation. Based upon the comments there, I suspect your new question is related to the ratio of $\frac{C_D}{C_L}$ and how that relates to the rest of the equation(s). To be honest, that sounds like something that could be clarified within the existing Aviation question and not worth opening a brand new question about.
On the other hand, if you have a broader question that was sparked by the answer to your Aviation question and you're wanting to understand the engineering behind that question, that would be a valid question to ask here.
And as a final point of SE netiquette, I would encourage you to edit your comments on Aviation into your existing question and then remove those now obsolete comments. You don't need to say "EDIT" or any other meta-blather in your question. SE provides a revision history so anyone who is curious can see how a question evolved.
