Hi YF
I did a bit of soul searching over doing a practice sim as 'down under' there is only one choice at it isn't cheap. It was something I couldn't justify financially so...
I did numerous hand flown raw data ILS's on my current type (thankfully my current operator allowed that);
Downloaded 'ready for pushback' and flew the profile a million times
ok total nerd alert but it was useful for orientation, learning the profile backwards and getting your head around those bloody bugs!;
Finally, prayed that 10 years roaring around in pointy jets in a previous career counted for something.
I was in HKG with a couple of 747 drivers and they said the sim didn't fly like a 747. Take from that what you will. The SIM was very very unstable attitude wise ESPECIALLY in bank. Whether or not they give it a way aft CoG or its just testing nerves the machine was a bloody handful. Take your eyes of the ADI at your peril... on the bright side power + attitude = performance and the numbers they give you are spot on.
If your wondering I start in Sept on the A330 so must have done ok
