At least the US made an ATPL mandatory for airline pilots. Here in Canada we still have 250 hr zero to hero’s going into Part 121 equivalent right seats. Sadly this will only change when, not of, we get our Colgan.
One issue that is biting on. both sides of the border are the instructor instructors. The good senior instructors have mostly been sucked up by airline or corporate operators and the ones remaining are all too often the fu*ck ups who got never got hired or more often were fired from their commercial air service.
The quality of new instructors is IMHO well down from where it was even 5 years ago. I was lucky as when I did my initial flight instructor rating in 1986 I was taught by an X Military guy with 30 yrs instructor experience including 8 yrs in the Military teaching on Harvard’s (Canadian T6).
My ego took a big beating but I was a pretty good pilot and instructor when he was finished with me.
