My bad. I focused on the FAA writing the reg, as opposed to the law directing the Feds to do so. The Airline Safety and Federal Aviation Administration Extension Act of 2010 is the name of the bill, sponsored by Rep Oberstar, a hard-core ALPA supporter. The end result is the same - a bad bill, with foolish requirements, in part passed to give ALPA an item it has long wanted.
If you haven't followed this part of ALPA's want list, they have for many years supported anything that artificialy might create pressure on pilot availability, i.e. working to create a pilot shortage. The ALPA mag had a large article about just that, using a shortage to enhance contracts, somewhere back around 2004ish.
Regardless, it unfortunately comes back to logic and common sense having far too little to do with a final rule.
The irony is that this is the same logic that provided a potent weapon for APAAD, SWAPA et al when working to change the age rule: If newbies are popping straight out of college and into the right seat of an RJ, then it makes sense to keep more experienced pilots in the cockpit. APAAD ran a wickedly effective ad lampooning 250 hour new hires in The Hill, the primary Capitol Hill newspaper. It got lots of attention, which added to the cosponsors of the age change bill.
The further irony is that CAPA and ALPA pushed for this new bill/reg and got it. High hiring reqirements might bring better contracts. But...these same requirements also might, down the road a piece, bring another extension of the retirement age.
I wonder if they figured that in?
I'm guessing you never had to sit left seat in an RJ with some wunderkid child of the magenta in the right seat trying to keep up with the airplane and either doing multiple things that make you question who gave them their CMEL or outright panicking the first time you get an abnormal and trying to do something REALLY stupid where, in both cases, no matter how much you try to talk them through it, you basically have to take the airplane, tell them to sit on their hands and shut up, and deal with the situation.
I had the dubious pleasure of being at PCL when they hired a TON of those kinds of pilots and it made life rather irritating, and made me start watching what airplanes my family got on when a wunderkid got paired with one of our near-obese older pilots that were coronaries waiting to happen.
I shudder to think what would have happened in an emergency with one of those crew pairings if the CA checked out (stroke, heart attack, whatever) and the new-hire 250-hr wonder was left to deal with it. Probably something like the Colgan accident. Or what happened with PCL 3701.
Having directly experienced what happens when you put a 250 hour pilot in the right seat of an RJ (serious degradation in safety), I've been advocating an ATP for ALL 121 airline pilots for about 11 years now (go back and research my postings, you'll see it pop up once every year or two when this topic comes up).
I guess at 41 I'm just an old-school, 3rd generation pilot, been around this all my life. Fly the Wing and Aerodynamics for Naval Aviators is sitting over here on my shelf, well-read and studied, not because it was required in a course, but because someone in my career shoved it under my nose and I wanted to be a better aviator. You give that kind of training to ALL pilots, make them UNDERSTAND the aircraft they're flying, HOW it works beyond just pushing the buttons and following the pretty magenta line, then make them develop stick skills that PROVE they can handle the plane, not just a rote checkride and a question and answer bank they can memorize, then MAYBE, just MAYBE I'd be OK reducing those hours now required.
Otherwise, no. They need the experience. Personally I believe the ATP course should REQUIRE mandatory understanding and oral testing on Chapters 1-5 of Aerodynamics for Naval Aviators and the entire book of Fly the Wing. The testing standards for the FAA for the CMEL and ATP are laughable; that's part of the problem.
Any idiot can memorize 1,000 multiple choice questions enough to get 70% and flying a Duchess through maneuvers isn't exactly equivalent to blowing an engine on takeoff so badly it catches on fire, kills half the hydraulic system, and makes the obese Captain stroke out from the sudden shock and stress, leaving the F/O to deal with all of that on his own.
Show me a training course that can teach that successfully and I'll gladly retract my position.
