Draw the wind dot UP
I would suggest that if PompeyPaul has been shown wind down then all you are doing is adding to the confusion, this is one of those debates that you will get 50/50 and goes on forever!
Using wind down, my own way of remembering this is -
Wind down from center
You then want everything in the following place:-
TAS under the center dot.
Heading at the top
GS under the wind arrow
Track against drift at the top
Drift the same amount and on the same side at the top and under the wind arrow
Using this you can find any two unknowns if you have the rest.
i.e. in the normal problem (find hdg/gs) you do not know the heading so you cannot put it at the top, you therefore put in an approximate heading (most people start with the track) and 'balance' the drift to give you the correct heading & gs.
So, just remember where everything should go, then put everything in where it should be as much as you can then you can find anything else you need, even with a bit of fiddling.
