Thanks that is much appreciated. I will give all that further thought this evening.
I still can't help thinking that this is all a bit convoluted for a 1 point question in a 45 minute exam. There must be a shortcut to work this out, unless all they were after was that the load factor reduced and rely on there only being 1 answere that fits.
Who can know the mindset of the CAA!
