If you have never been at Samedan - which is a high elevation airport with a visual approach descending into a narrow valley (to turn a Falcon 900) and a somehow short runway depending on the condition, closely surrounded by very high mountains - and you are not proficient with winter ops and the area, I would recommend to prepare very carefully and have some options if you are not going to make it.
You will find a lot of interesting reports in
BFU - BEAA - UIIA - AAIB from those unlucky pilots who tried to trick it out with smaller aircrafts then a Falcon 900.
