Sir , "permitted" but not the best practise ... many operators are not allowing to do it ...
you are talking about the A330 , i have lived many times where people were not waiting for the "flap open" msg , leading the APU not to start , fuel line not pressurized enough ...
"hey maintenance , the APU is not working" ... "oh yeah really...?"
permitting , allowing , these mean they can be done but not the best.
