Thanks, Ken.Yes, the PMDG is a great implementation of the NG! Start saving your pennies for the 800/900 series, which will also update your current aircraft with TCAS, etc.BR,Frank

Hi Frank,Funny thing you mentioning the 800/900 Aircraft; I've been 'wading' through the FMC User's Manual all afternoon, I thought to myself 'maybe I should upgrade to the 800/900 version now and not wait until I've read all these Manual's again'. So, I ordered in a bowser of printer ink :)and decided to go for the update tomorrow. I there a 'big' increase in FPS with the 800/900?I think I'll draw a line under this thread now. I've planned a flight from Heathrow EGLL to Stuttgart EDDS for tonight to see how much of the FMC Manual has stuck!!Thanks for your help and support, see you again sometime.KenSomerset, England
