From a Canadian perspective, we have new rules coming into effect June 1rst, 2019 that apply to all UAV's. As part of the new rules, they introduced to levels of certification, the basic certification which roughly is similar to the US section 349, and the advanced operation certificate, which goes beyond the US part 107 with a checkout flight by an accredited flight reviewer. To get the basic certification was not a slam dunk, and if the FAA introduces an online testing system, like transport Canada has done, then you may be in for a shock. The Canadian transport Canada online test even for the basic certification was far more difficult and encompassing than most people had imagined and if you go online to youtube, you will see a number of complaints about it and how some well known flyers had to take the test multiple times to pass even the basic level. In the Canadian online test for the basic certification, there are 35 questions, you get 90 minutes and it's open book. Questions had to do with 1- air law and regulations (14), 2-sUAV airframes, power plants, and systems(2), 3-Human factors(2), 4- Meteorology(2), 5-Navigation(4), 6-flight operations(6), 7-theory of flight(2) and 8- radiotelephony(4). The number in brackets are the number of questions in each topic. The questions are randomized and not in order of the basic sections. Further, if you have to retake the test you will get a different set of 35 questions within those categories. a minimum of 65% is required to pass. It took me more than a few days of brushing up and studying but I managed to pass my basic certification on the first try with a 90%. The advanced certification is a 50 question test to be done in 60 minutes with a result of 80% minimum to pass and covers the same plus a few more areas with a different proportion for each category. I've been told it's more challenging than the current FAA part 107 exam. I am busy studying for my advanced certification as I know it's going to be a challenge. Oh one more thing, in Canada, even if you have the advanced certification, your sUAV needs to be certified for advanced operations too. Luckily, DJI has certified most of their sUAV's for flight in controlled airspace.
I would not be surprised that the new FAA testing will mirror the Canadian Transport Canada system. As of today, Transport Canada has not made it clear if there is an exemption for those flying at a MAAC (AMA field in the US) field. It was originally proposed that MAAC fields would be exempt from the new rules requiring certification, but as the new rules take effect in a few weeks, the lack of news makes me think that an exemption is not forthcoming. I do hope that the FAA doesn't introduce some of the more crappy rules that Transport Canada has done. For example, there is a limitation on who can fly. You have to be a Canadian citizen to be certified, so any visitor would have to apply for a SFOC (special flight operation certificate) to fly at a specific time and place or find a certified pilot to fly with. That is quite an onerous imposition to visitors
