Dear Listers,
Pacbell is suppose to be working the Matronics connectivity issue this
morning. Intermittent connectivity is still a issue although things are
better than yesterday. They will probably be doing some intrusive testing
on the line later today which will disrupt connections during the test.
More information as it becomes available!
Thanks for your patience.

(reply from long-ago message about pulling the prop control to coarse
after going to idle power--to reduce prop drag.)
Tom: Doing this will be effective as long as you have oil
pressure, and the oil pressure will be there as long as the prop is
rotating, engine running or not.
Also, the drag of a flat-pitch prop is only effectively there as
long as the prop is spinning. If the engine has quit, and the prop
stopped, (quite difficult to do as long as you have airspeed, unless the
engine has seized), then the prop drag is drastically reduced anyway,
and you will not be worrying about going to coarse pitch then. The
prop's drag is only extreme while rotating, from the disk effect.
(effectively, while the prop is spinning, you are pushing a disk through
the air, rather than just the blades.)
This situation, by the way, is one reason for experimenting with
this effect. The drag changes drastically either with a coarse-pitch
setting, AND with a stopped prop, so we need experience in exactly WHAT
TO EXPECT from the plane in these situations. Experimenting with
changes in the aircraft's performance is a whole lot easier learned in
practice than in actual instances. To learn these kinds of things in
real life is "rather challenging."
(PS. Just back from the wedding trip from Colorado to Florida
in my 180. New wife got to experience a "precautionary landing" after
one cylinder's plugs fouled out completely, and then helped out in a
freezing hangar on the last day of the trip AT MIDNIGHT as we finished
changing out a rather thoroughly cracked cylinder. I think I have a
winner on my hands.)

Lee,
Never thought about that if the prop was turning, there would be oil
pressure. What about the fact that my prop won't cycle under 1800 PRM? I
guess I should try it after landing one day to see what RPM is needed to see
movement in the prop.
Always enjoy learning something new. Take care have a merry holiday season.

I seriously doubt if the wind milling RPM will be in the governor range, you
will always have a flat pitch, read HI RPM setting on the prop as the
governor tries to hold the RPM at the low setting, on my engine that is
around 1400 RPM. Stopping the prop is a good idea if you have the altitude
and time, it can easily be accomplished by bringing the aircraft to a near
stall. I have done it, not in my Rocket, but in other aircraft. Getting
the prop moving again takes a pretty good dive up to about 130-140 Knots.
There is less drag with the prop stopped. I would still bring the RPM lever
to low, you never know it might help with a better glide, but I doubt it.
