the big Falcons,
not unlike other airplanes have a very powerful stabilizer..
given the huge difference in required trim settings between light and heavy weights for such aircraft, the charts are in every QRH and AFM, it does make a huge difference where your trim is set for take-off..
everybody operating the type should be familiar with that fact and it is well known..and it is in the FAA approved AFM and loading manual..(has to be there by regulations..)
maybe some people still think, that just because you can barely load most bizjets and also the Falcon "out of CG limits" that the required trim settings for a given weight and CG are of secondary importance, which is huge mistake..
can't believe that an experienced and qualified crew does not know the importance of correct trims for take-off..
then again, guess if some people can sue a fast food chain for zillions of bucks in the US, just because the coffee was as hot as advertised and they burnt themselves, that some flyfolks think they can sue a manufacturer for not producing a fool proof plane..
beats me..
take-off trims are vital, even and especially also on such well designed planes as the Falcon 900/900EX series, that have, by their nature, such a wide weight range as any other long range jets too, for that matter..
and, should some SIM instructors not having emphasized the fact, or, worse, should have distributed the wrong dope on that issue, well that's another problem..
but then again, smart crews would never believe it, if such bull... is told at training centers..
