Hi,
Are you talking gross or net figures ?
I work for a french company flying under a french AOC, CJ copilots receive something like a monthly 2300 euros gross salary. In France, like in Germany, taxes are quite high. That means they end up with around 1600 to 1700 take home salary for a single guy copilot.
As you may know, there are plenty of type rated pilots available on the market, so, why a company would take the risk of hiring guys on a full time contract if they can have them as freelancers ?
