[first forum post]

I am almost ready to commence training, after a few trial flights. I have been watching developments closely for over five years, trying to get a handle on (fatal) accident stats for the modern generation gyros. More out of curiosity than anything, as I have a stats background, and to be able to satisfy myself that I have evaluated the risks as accurately as I can. I do acknowledge that the risks have fallen dramatically since the Bensen days. But by how much?

One of the pieces of the jigsaw I am having to guess at is the average annual hours flown

Another piece of info I'm looking for is approximate start dates of manufacture, and growth rates. [I estimate about

I am focusing on the

I notice a few users are keeping tabs on the number of craft flying worldwide, and I would estimate around

I've come up with a model to estimate fatals per million hours flown [a common metric applied to other forms of GA and transport in general].

Before I publicly churn out some numbers, I would appreciate comments on my general approach, and best estimates for the hours, etc I mentioned above.

Safe Flying!

UPDATE: * maybe my initial estimate of 4000 was a tad high.
