I am not familiar with any Airbii, so ask genuinely; is it possible in the A380 to dump more fuel than this crew did and, thereby, further reduce the landing weight?
I'm certainly not casting any aspersions, nor suggesting any wrongdoing but I'm intrigued to know why the crew decided to land at the weight they did. I expect they had good reason but I don't suppose we'll ever find out the truth and, therefore, we can't learn what they did well and maybe didn't do so well.
