Dude,

This could reduce the stalls, at least on approach.

Oh? So how many have stalled on approach again? Right, none.

Yet.

Don't get so frigging defensive. My point is that the Cirrus can be hard to
slow to approach speed. It takes more care than many other planes because
it is slick, and you cannot control the pitch of the prop to add drag. If
you had speed breaks you would allow the pilot more options to control
descent given that right now the system that governs the RPM/MP has limited
ability to slow the plane without cutting the throttle.

Bottom line is that if a person has speed breaks, he is less likely to fly
slow because he can shed speed whenever needed.


It would also reduce
the severe shock cooling they are seeing due to their engine control
system.


So you can prove damage through shock cooling? Wow! I know no one else who
can. And where is the connection to the "engine control system"?


Presently, according to some COPA members, there are many people having
excessive engine wear and needing lots of cylinder work early. One
suspected reason is shock cooling due to pilots cutting throttle to get the
plane down without gaining too much speed. The cirrus design simply adds
more penalty to poor vertical planning than most planes, and so the engine
is often asked to pay the price.

Another theory is that the engines are constanlty being run at set rpm's
that may not be the best rpm's or the smoothest. The pilot cannot control
it.

Bottom line, the phony Fadec system isn't really all that good.
