Unfortunately it’s well known within industry that standards have dropped significantly in recent years, particularly with regards to CPL and IFR rating graduates. I’ve flow with a couple of junior CPL holders who shouldn’t even have a PPL!
Sad, but true. Even as far back as 2000 it was said that someone passing a CPL then would not have passed a PPL a decade or so earlier. I don't believe it has improved since (??)
One other issue is that the CASA safety briefings etc held these days don't seem to be attracting the young flyers - Most of the attendees of the ones that I have being to are over 50.
