The crux of the question posed by Aerocom2 is "Why do regional airlines employ QF cadets instead of qualified G/A pilots?" I didn't understand why companies like Air North would train a cadet only to see him/her depart in two years time. I've since been told that Air North are very happy to have the cadets as most G/A pilots leave after a much shorter time thus causing continual employment problems - the cadets actually give them greater staff stability. The G/A pilots that do stay around are guaranteed a command very quickly.
