If your assessment is carried out on the -400 it will be all raw data anyway so in fact will be very similar to the -200, just slightly different attitudes.so read and learn the guidence notes you've been sent.................the ILS presentation will appear on the PFD (Primary Flight display) so it makes the scan real easy as everything you need is on one instrument. As soon as you select Vref flap 25/30 in the FMC the required speed bugs are automatically calculated and will appear on the speed tape on the left of the PFD. If you have had a practice in a -200 sim it will probably stand you in good stead for the ride the only other difference is the -400 is a little lighter on the controls !!!! Learn the pitch attitudes and EPR settings from the sim brief and RELAX..........The guy just wants to see if you can flyand if you are "Trainable".....not catch you out or anything, so you will be well briefed and given all the information you require !!!
