Above the Clouds-
Must chime in here.
The Global is not "..a relatively simple airplane". It has quit sophisticated systems much more like an airliner than a small biz jet. However, because of its high automation it is relatively simple to fly and the workload is very low.
Anyone can learn which switch to press but an airman with experience will understand why and what has happened when that switch is pressed and perhaps more importantly what NOT TO DO when things don't happen as expected.
Also, I too know of at least 2 Global FOs hired with less than 1000 hrs TT...in Europe. This probably wouldn't happen in US in my opinion.
