Dassault Falcon does not have a huge range of business aircraft, but its three series - the twin-engine 2000 and the 900 and 7X trijets - compete at the very top of the market. The French manufacturer has cleverly adapted its two smaller types, the 2000 and 900, over the years with enhanced cockpit technology and, now, winglets. The latest iteration, the 900LX is a update of the 900EX with blended winglets. We have not only flown the aircraft in this week's issue (30 November), with Peter Collins putting it through its paces over Dassault's factory near Bordeaux, but have drawn it too. Tim Hall's remarkable cutaway poster - free with the issue - shows how the aircraft is constructed.
