We should hear about it from EASA and possibly other regulating bodies before a RTS if they deem it necessary. Might not apply specifically to took you but just as there are differing views on initial training others might not follow in lockstep with the FAA.
And you need to understand that an FAA rule implemented after Colgan 3407 in 2009 doesn't suddenly make it the absolute gold standard and anyone who doesn't follow that path and that path alone is any less of a pilot. After all you do need to consider the amount of non Cessna training that a pilot goes through before ever setting foot inside an Airbus/Boeing flight deck even to do base training on said type. Unless you mean that airlines from around the world, from major international carriers to regional LCCs are conducting thousands of safe flight operations daily only due to sheer luck.
The "gold standard" that should be applied globally, and should have always been applied, is requiring an airline transport pilot level license for all airline pilots.
Every regional pilot, or aspiring regional pilot in the US should applaud the 1500 hour rule, it's resulted in significant increases in pay at that level.
There are decent, and not so decent ab initio and cadet programs, and then there is the push for MPL. I am fully aware of the "non Cessna" training pilots receive in these programs. These programs produce acceptable systems managers, they do not produce exceptional aviators. A pilot who isn't even qualified to carry passengers in a light airplane by themselves, has no business in an airline cockpit.
I spent several years as the FAA equivalent of a line training captain, and a line check airman before the 1500 hour rule, and have spent thousands of hours working with very low time airline pilots. Good people, but I don't want to be in the back when the captain becomes incapacitated, or the airplane develops serious problems.
And you signed off the pilots you would not want to fly with?
The ones that met the standards, and I was convinced would be safe line pilots got signed off. When the overall experience of the new hires went way down, and the amount of line training they received almost doubled, I resigned my CKA letter. The job became too much work, and the exposure to unwanted attention from both the company and FAA was too high for what we were paid at the time.
In the 30+ years since I started, the regional industry has come full circle and then some. In the 80's, you couldn't get a job flying a Jetstream/Metroliner or Shorts with less than 2,000 hours total time. As a new hire, my class had a 50% washout rate. We got 25 hours of line training to figure things out, or we were out the door. If the training captain had to take the airplane away from you, that was an unsat, and the training manager would decide if you got sent back for additional training, or were let go.
Then the 90's brought "pay for training". Cut a check for north of $10 grand to the company the first day of training, but people were still lined up out the door for the jobs.
9/11 brought us the "lost decade" for American airline pilots. Very few jobs, very competitive.
When things picked up again, there wasn't anyone in the pipeline, so the airlines started scrambling. New hires could start from an approved 141 school with as little as 200 hours. However, the amount of simulator required to get them out to the line went up, and the amount of line training also had to increase. Some had as much as 100 hours of IOE before they were ready to go be line pilots.
Today, with the 1500 hour rule, regionals are paying huge bonuses to new hires, I've seen as much as $50K advertised. Some are hiring right into the left seat, or forcing first officers to upgrade to captain as soon as they meet the minimums.
I realize I'm in the minority here, but IMHO the only training that should be going on in any airliner full of people is learning the difference between the simulator and the airplane, and the specifics to the airlines route structure. Not teaching someone with very limited actual airplane flying experience, and some simulator experience how to really fly, and manage a 150,000' or bigger airplane.
