Sim ride
Practising on Microsoft flight sim is a good idea:
It will help you learn where things are on the EFIS display (assuming B747-400 sim or Airbus sim);
Learn how to effectively scan the EFIS primary flight display and Nav display;
Practise the profile so that it becomes second nature (It tends to get quite busy in the sim).
Here's a few more tips if they haven't been posted already:
Don't get 'behind' the eight ball............ stay ahead of the aircraft (it's like a PA28 on steriods);
Keep calm and cool (easier said then done, you want to be seen in your best light cause the airlines want the best, if you have spent time preparing then this shouldn't be a problem);
They would have given you a profile so learn the speeds, drill sequence and nose attitudes for the various stages of flight (Get the attitude right and you won't have problems);
SCAN SCAN SCAN SCAN.
Practice and preparation makes perfect............ Good Luck!!!
