Thanks Chillpill for that explanation. Being very much pre-FBW and even then 10 yrs before, I couldn't get the hang of the A320 sim except in what I think is direct rule ie fly it like any aircraft I had previously flown. Not being a 12-year-old any more I couldn't make head nor tail of the pre-flight programming but you have shown me where I was going wrong. I'm going to treat myself to another hour or two, then I'll be ready to take over when the experts fall ill on our next trip to the Canaries
