other countries charge applicants for the country's aviation agency's efforts/costs for certification. Yes, that could mean an agency could generate revenue simply by rejecting an applicant and making them go through the costs again.
The reason for this is the difference in how the civil aviation authorities are funded. In the US they a government funded via taxes. In the most other places like UK or EU, they are user fee funded. For example, if you want to use a runway in the EU each aircraft must pay a fee each time, they land on the runway with some charging the takeoff instead.
Or if I wanted to obtain an EASA approval for my FAA repair station, I would have to shell out about $25k to fly the EASA inspectors over here and pay the lodging, meals, and time they spent inspecting me. Where the FAA would not charge for the same service until “recently” after they shutdown all the overseas IFO locations and now charge a nominal fee for the overseas service.
I don't know all the details of the ICAO rules. But from what has been discussed there, they sound complex.
The ICAO Articles and Annexes are less complex than the FARs. If you want complex read the EASA rules.
1. Airlines and aircraft that want to fly internationally. They follow the rules similar to what we have now so the ICAO will be happy.
2. Airlines and aircraft that will stay domestic. The FAA rules are dramatically simplified as I suggested above.
Very doubtful. As I mentioned in a previous post, a majority of the regulations we have today were existing in the US CAA
prior to the founding of the ICAO. And the reason why was operators, both domestic and international, were killing their passengers because they preferred not to follow the existing safety recommendations of the day. It’s the same reason the Aeronautics Branch was cut from the Commerce Department and made into the independent CAA and the CAB and the 1st CARs were written. All to protect the flying public from those cheap operators.
While I don’t know what your experience is with the aviation insurance industry, I can assure you they prefer to place a lot more importance in risk management in making decisions vs how much they pay out on an injured or dead pax. The question is, why haven't they done that now and required more safety compliance if that point is important? But keep in mind, to satisfy those who don't want rules, the FAA provides E/AB and other Special AWC routes so that you can fly/build whatever aircraft you want, free from any oversight.
Perhaps send an email to Southwest Airlines and see what their take would be of your ideas? Or send it to the CEO of Ryan Air in the EU. That guy wanted EASA permission to create a "standing room only" fare and have pax stand in the aisle like in a bus.
