REFLECTOR: barn door speed brake

[Ann DaSilva]

When I was flight testing for Danny back in the early days of Velocity I
flight tested the speed brake on the standard Vel. (BIG ORANGE) to 120
knots, and then it was decided we would not push it beyond that.   Sam D.

John,

Thanks for the comprehensive reply on the SB issues.  It sounds like our
situations are similar.  To add to your knowledge base, and as best I
recall the conversation with Scott Baker, the factory encourages the
"all or none" on speed brake deployment, but I too have a momentary "on"
for the deploy side and will probably count in my head over having a
gauge showing degree of deployment, but that's a good idea.

I also asked SB, and I would guess many have before me, on the notion
about lessor angle ought to mean higher speed limit.  Baker declined to
speculate, and added a warning to me about the panel going thru the prop
if the envelope was pushed beyond tolerance.  He did mention no attempt
was made by Velocity to test the high end of the speed range for the SB.
As I recall it he said that they decided 110 was safe and pegged it at
that.  ...or you might say a traffic pattern speed control device and
not designed for arrival descent use, or ATC requests to increase rate
of descent.
