While yes, there may be some constructive aspects of aviation in the US that merit emulation, and even a few things that FAA still does right,...but do not for a minute think that FAA is a model to broadly copy, or that GA and other US operations are not also under severe cost pressure and flawed criteria pressure from a severely dysfunctional FAA here in the US.
Much of FAA's criteria is obsolete, counterproductive, unnecessary, or overspecified, if not flat out "inappropriate", and in instances is now leading to less safety rather than more safety (by unnecessarily inhibiting advantageous advances).
The US system and FAA are suffering from decades of outdated 1940s to '60s based operating concepts and criteria, for a now entirely obsolete and vastly over-expensive air traffic system. This is also largely true for an often bureaucracy laden counterproductive aircraft, airman, and operations certification system.
That's why the airlines and others in the US (e.g., many in Congress) are now pushing to break up FAA and split out a separate ANSP this fall. GA here is reeling from entirely inappropriate and dysfunctional criteria (e.g., 3rd class medical mess, faulty mis-specified and inappropriate equipage requirements like the WAAS driven FAA ADS-B 2020 deadline, glider avionics ANPRM), as well as many areas of unnecessarily high costs driven by bad or outdated FAA criteria (I could cite pages of examples from TSOs, to rules, to ADs, to STCs to NOTAMS).
Further, NextGen is presently heading straight toward a $40B failure that just simply won't work, at any cost. Even 26 states (now starting to formulate their own UAV criteria), as well as Amazon, and a host of other UAV entities, are now attempting to simply bypass or leapfrog FAA, in exploring their own recommendations for ATC design, as well as chaffing at FAA's seriously flawed and counterproductive ANPRM for UAV policies.
So don't bank on necessarily copying FAA's currently fouled up policies! Many in the US here are actually hoping that Canada, Australia, or NZ eventually someday get it figured out, and then perhaps serve as a model for reconstruction of FAA and a separate ANSP O
