Exam Question about Weight, Balance and MAC
Hi all.
Recently I did an exam, and came upon this question which I would like to share, and want to know what do you think is the proper answer, since I can't remember the options.
The question went on like this:
The BOW for an aircraft is 4,200 lbs and is located at STA 90, at 20% of the MAC. The fuel weighs 500 lbs and is at STA 100, at 30% of the MAC. Where on the MAC is located the CG in % (for the fuel)?
I've put the (for the fuel) in parenthesis because I think the question was for the fuel CG, but maybe you can help me calculating both the fuel CG and the total CG.
Thanks for anyone that helps!
