Hard to receive quality training when the trainers also have no practical experience. I’m not sure if you are an experienced aviator or not, but if you are and you aren’t operating at a much higher level than you were when you first started, you are doing it wrong.
The reality is that the whole house of cards is built upon the fact that Boeing and Airbus have made it very very difficult to get yourself into serious trouble. When the technology backfires (Air France, Air Asia) it tends to go wrong. The only hope in those rare cases is that somebody has the smarts and experience to realize what’s going on. When they do you don’t hear about it because it’s an ASR, an item added to an RT or maybe an NTC.
Regulators, airlines and insurance companies are all comfortable with the risk. If they didn’t absolutely need 0 hour cadets in the seats they wouldn’t be there. It would be like it used to be and everyone would have experience. Cadets aren’t a superior way of crewing aircraft, they are cheap, necessary and an acceptable risk.
