Hang on?
Whatever happened to cross checking fuel on board versus fuel required versus fuel ordered versus fuel loaded versus fuel in tanks (Indicated)?
Then fuel on board versus fuel burnoff?
And, in flight fuel management; Cross feeding?
Seems to me one would do a little bit of xfeeding prior to shutting one down?
If the journalist report of CASA statements & actions are correct then I suggest someone needs to have a good look at CASA's capabilities?
