Without going into the tech details , my advice to you is if your going for a checkride then , when your established on the ILS if your in IMC follow your FD's like no other, if your visual keep your ROD at 700 fpm and that should give you a kisser ...... this will work for weights anywhere between 59 upto 64 tons . for now I suggest you forget about the power bit cause thats what the fadec and the autothrust are there for .
all the best
