TimmyG00 did a great job there.
I return to it for reference regularly. It has the hallmark of someone who has had 'hands on'
Two things stand out for me both of which changed the sim. dramaticaly:-
First the display check for NB showed what I'd missed previously.
Second the TMA exposition on lag/lead fans etc was a revelation.
I'm only highlighting two usefull features - there were many more.
Many thanks Timmy.
