You should have no problem operating anywhere..
Only place I cant give you any idea about is Africa. Never been there, never plan on going.
Just be sure you have the world in your database, Im sure a newer GIVsp has triple honeywell FMS's...I guess you could check ahead of time to insure RAIM is availiable in your areas, but I cant imagine that would be a problem.
Aspen accident? well, the NTSB report is readily availiable...It was night, weather was approx 300/1. Mins for the approach are around 2000/5 if I rememeber. That accident had nothing to do with Gulfstream or Aspen....unfortunantly. The Plane flew into the side of a hill while scud running FAR below minimums in one of the more challenging places to fly into.
Many companies will not operate into Aspen unless Daytime and the field is visible from Red Table (IAF) Those are fine with me.
