Hello again guys, I found a solution. I searched and searched for hours and finally found a video on how to solve for Track and GS with the CRP-5 Wind arm edition.
And I do not agree, CRP-5 is not crap, it's very effective. A circular flight computer is completely unnecessary and would be a waste of money. CRP-5 or CRP-5W is all you need for EASA ATPL.
Question banks and ATPL books use the CRP-5 When explaining the calculations of the different things, so I am pretty sure that the CRP-5 Is the main flight computer that is used for ATPL exams.
Take care
