PS The MLW for an A340-200 is 181K (-300 = 192K; -600 = 259K)
Actually the MLW seems to depend on the variant of the 200. I know of two types I have flown which are the 212 at 188Kg and the 213 at 190Kg. You are of course quite correct about the 5000ft limit for fuel jettison. The overweight landing checklist is not that complicated and a lot quicker than waiting to dump. If my memory serves me it just directs you to check the landing dist and switch off the packs to increase available thrust. After that you just try and put it on gently and use max reverse. Heard the story before and it's still a good one.
