I dunno where mine is anymore, seeing as I haven't used it for 5 years
I preplan properly on the computer which works out my CoG, SoG, Compass headings and all that stuff, then if I need to change it in the air I use rules of thumb, and GPS to give CoG, SoG, and actual winds......
I tried planning properly for my IR checkride several years ago, filed my flight plan which included a SID, then picked up my clearance and it took me a completely different route anyway......so now I just make sure I'm not going to run out of petrol and off I go. If I need to divert, there is always the Goto button
IO, are you now a member of the Elite then (if so, congratulations!) ? Are you back, I'm off over there on Wednesday......
Cheers
