No, it's overwriting on every flight. It wraps when it gets to the
end of the memory space and goes back to the beginning. When it
wraps, it appears that there's a 10% or so risk of a security failure
on that one flight log. Roughly speaking, you have about a 50/50
chance of seeing a security failure every 500 flight hours at a 4 sec.
rate.

I like my 302. I'm just getting ticked that this thing is still
effectively in beta and that no one is working on the software to make
it the *great* instrument it should be.
