why would they adverstise 100hrs if they really want 2000hrs then?
Its called minimums. They will take someone with those hours however would only happen is there is no on else left.
Its a supply and demand thing. With a lot of pilots applying they will employ the best qualified such as the 2000hr pilot, however when they are out of 2000hr pilots they will start taking 1500, then 1000 and so on.
