Thanks for that - it's the final day of the weekend here so engineers not on duty (no sleeping overnight on the office floor for them - lucky tykes!). I'll check back with them after my rest day to see if it was me getting hold of the wrong end of the stick (as usual) or a mis-read on their part. Mind you, I did post those figures immediately after chatting with their head honcho, so I might have actually written exactly what they said...
(in other words, blame someone else - ideally the engineers... typical pilot, eh?)
