I think the OSH people should consider multiple approach patterns based
on speed rather than a/c type.  You could pick whatever one made sense
but you would have actually to fly that speed.
***  I agree with that one.  Why should a IV-P and a IV-PT fly different
paterns: just because their exhaust smells different?  It would be an
improvement albeit less challenging and hence less rewarding.  But then,
a mid-air could ruin the entire day so perhaps less challenging is
better. ***


. . . but have a hard time figuring out how the patterns merge at the
airport.  If somone has done it and knows, I would love to hear.
***  It does work if all pilots manage their speeds.  I have engaged in
the merge from the bottom layer in my GlaStar.  After Fisk on extended
downwind a twin at 135kt decended from overhead and on my right.  He
decellerated as he matched altitude, turned base, and was cleared to
land on the the far dot.  I was cleared to the close dot and we were
both rolling out at nearly the same time.  Worked just fine. ***
