I am currently studying for my EASA ATPL (airline transport pilot license) and one of my subjects is General Navigation.
I have stumbled across this question (picture) that has completely stumped me, I have not been able to find help anywhere else. I know it can be solved by drawing wind triangles but I am solely interested in solving it using the CRP-5 flight computer.
I am very much used to calculating desired headings for a certain track when given wind, but not the other way around. Any help would be greatly appreciated.
