Bill,
The point I was
trying to make is; 61 was a number that the feds came up with out of the blue
when they set that figure as the minimum Vso for the certification. They could
have picked a different number just as easily. That is why I said that the
number was not significant. However, the article’s case was built around that
number as if there was something magic about it.
Regards,
(:

Everything you say
below is absolutely true. The reason that 61 knots is even marginally
significant is that is the max Vso allowed for single engine airplanes
certificated under part 23. Since we are not bound by part 23 our Vso can be
higher. Hence, this is just one of the many differences one might find
between certificated and experimental aircraft. Why FAA jumped on this
number that has no particular significance for experimental aircraft,
I have no idea.

There is nothing holy, sacred or
even significant about a 61 mph stalling speed. Why not pick 41 or 51 or 161
mph? All aircraft that are used by the airlines have a stalling speed
greater than 61 mph. Does that make their aircraft unsafe?
The fact of the matter is that a
given aircraft has many "stalling speeds". The speed varies with weight,
number or "G" forces and even altitude and temperature will affect the true
airspeed at which an aircraft will stall.
It appears to me, that the
person who wrote this article did so with an eye toward damning Lancairs and
experimental aircraft in general. The Lancair aircraft that landed on the
beach did not do so as a result of a stall, but mechanical failure. So why
the fascination with stall speeds? Even the widely referenced "Piper Cub"
will stall with just enough speed to kill a
person!
I can address this article from
many many years of flying experience that include: Piper Cubs, jet fighters,
airliners and Lancair aircraft. I have often stated that the Lancair Legacy,
that I fly, is one of the best flying aircraft I have ever
flown.
