Don't just take it from me, although I HAVE been using back button AF for some years now...do some research. There are lots of tutorials online, presented by seasoned pro photographers. I had my doubts at first, could not see much advantage....(just as I did with digital cameras whilst still shooting film). The penny finally dropped after much perseverance and after getting used to it...and it does take some getting used to...I now use back button for all my photography, of which aviation is a small part, though that makes no difference anyway.
Just google Nikon back button AF...plenty of good info and explanations of the function to help you decide if it's worth your effort trying it? All of my colleagues/friends who have done the same as myself, now remain back button AF shooters! Good luck, hope this all makes sense and helps?
