how far do you reckon they will go with stall testing on the a380?
All the way, certification requires it. And, as a special bonus, the Australian CAAS will want a little bit more because QANTAS have ordered the A380, just as they did for the TAA A300 so many years back.
Mind you, all the way might be a great big nothing, minimum 'Z' speed and all that.
