Things have indeed changed in RAAF training, certainly wrt how fair we are to students. These days students are provided with numerous instructors (not just one bastard QFI as you put it) and if we feel that the student QFI/instructor relationship is not at it's best the student will generally get an instructor change with no questions asked. Students are given several stages of warnings and remedial assistance to ensure they come up to speed. Generally, if they are suspended from course they normally come to understanding that the system has been fair and equitable to them. I say generally because there are still individuals out there who despite all this still seem to think that it is the system that is at fault and not them. At the end of the day we usually suspend students for their capacity and rate of learning. The majority of wings graduates end up doing the same job as their commercial pilots bretheren for the most part but they work autonomously more often and are placed in command slots a hell of a lot sooner.
