What system are you using, (codeco?) but i suppose the AHM50 data should be the same in all systems?
I used to do the F100 (a long time ago) on VLC in Holland and it was was always a ****** - normally weight limited - KLM UK "option 1". As far as the trim goes the aft holds are way to small and wing to far back.(especially with a full pax load and a full FWD hold),
Get some-one to spk to KLM city hopper or try the CODECO help desk in NL and see if the locals know anything about changes to AHM50 data.
