We didn't know you had a glass eye Michel!

Thank you, Graeme, Jim, Andrew, Ron and Rex, for your answers.
For the cruise speed, on the Jabiru list, someone was asking for the
performance of a Jabiru 2200 (that's your answer, Andrew) on a draggy
plane similar to a Kitfox or Avid Flyer. Several answered and the
person was puzzled that it may vary from 80 MPH (my cruise speed) to
122 MPH (one reported by a friend Kitfox 2 owner). I agree with you,
it must be exaggerated or, the owner has a special model 2 and likes
fast cruising! 
For the Va speed, I understand that it is a matter of comfort and that,
when in turbulent air, Vne is quickly exceeded as both vertical and
indicated speed needles move fast in all directions. But, I remember
that I once sailed into a French harbour to hear French yachtsmen who
had just arrived before me, talking about sailing in a storm ... when I
would have called it a moderate gale. It's all in the observator's eye.
As a novice pilot, any turbulence is a bit scary and I was wondering
what is real bad stuff that needs to stay at Va to avoid structural
damages. Do I have to loose my denture, wig and glass eye, to call it
significant turbulence? So far, the worse I have experienced is a short
moment when I felt my feet lifted from the floor ... it must have been
negative Gs. Is that "bad turbulence" or ... "moderate gale?"
I also like Rod Machado's saying: "Turbulence are like waves at sea,
only that you don't see them ... and that's what horror movies are made
of!"
Cheers,
Michel
