Old gripe, but once instructors are actually paid what it is worth to keep someone with a bit of dedication to the task, we might be able to keep some experience in this side of the trade and see some standards improving.
At the moment, bare minimum CPL's with no more intent than to get the minimum hours needed to apply for Jetstar are out there are still teaching circuits that incorporate 3 mile final legs, radio calls on every leg of the circuit, no thought to what's behind them on runups...
No problems with developing someone who wants to learn the trade, after all, we all had to start somewhere, but once again, if you aren't going to put 100% effort into where you're doing, don't bother!
