B737 Sim at Lufthansa FT Berlin
 

Does anybody know if there is any TRTO/AOC-holder using B737-300 Sim. at Berlin for ZFTT with LIFUS part done on B737-400? I know that they have certification just for B737-300 but what they say they can modify the software and cockpit panels so it imitates B737-400.
However the FSTD certificate states only B737-300 level D.
I am wondering if anybody uses it for ZFTT training mixing with LIFUS on B737-400.

We used it only for the -300 as 300/400/500 are one variant and can be flown without retraining from one to the other (unlike the NG which needed a retraining). However sometimes they forgot to change the aircon panel so we had the -400 aircon panel, pretty much the only difference in cockpit layout. No clue if someone uses it for ZFTT currently, but i would think so.
