I realy wasn't going to write again as our flight sim friend (Nats) seemed happy talking to himself.
But please, this is a tech forum. Amongst alot of other rubbish he has spouted this particularly needs to be addressed:
Yes, go to F1 straight from either 3 or 4 and yey, bypassing 2.
you never go from 4 to 1
Please take your references from the FCOM/FCTM/QRH etc. and don't read anything written by dubious posters on this forum.
