G'day Bob.
Busy studying away day after day. Even dreaming it in my sleep.

On Performance Exercise 5.11 question 3.

This browser does not support PDFs. Please download the PDF to view it: Download PDF

Question states, Find the minimum ballast fuel after using hard ballast.
I put 30 kg hard ballast in the nose
and then using your flow chart I put 15 kg hard ballast in the wing compartments.
This bought the CG in limits without using any ballast fuel.

However, on your answer it shows 17kg ballast fuel in the main tanks with no mention of using the wing compartments.

I am just unsure how I should answer during the exam.
I've attached a copy of my scribble sheet.

Love your work
