Sadly, I have significant doubts that this will happen. Perhaps I'm just jaded because I've been running into this brick wall for so long now. Hopefully your optimism is justified. Take the Yamaha-RMAX helicopter used for agriculture as an example of data. There's 2,500 of them actively flying in Japan (point of comparison, US Air Force has less than 500 UAVs). The RMAX has more than 2,000,000 flight hours with an impeccable safety record. Yamaha offered troves of data and requested permission to use the RMAX for crop-spraying over vineyards in California. FAA said, "No." That's the problem. The FAA simply says, "No". They don't say "You haven't met requirement X", there are no requirements that can be met by anyone. If 2 million flight hours is not enough data, what is?
