| Subject: | glide ratio again, flight characteristics, and riteangle |
--> RV9-List message posted by: "Welch, Ivo" <ivo.welch@yale.edu>
At 65mph, my plane seems to be in slow flight already, suggesting a lot of
drag.
so, my guess is that this is not such a great speed. This is not
scientific,
but when I flew yesterday at 80mph, my sink rate seemed to be only about
200fpm.
(I could be wrong. This is from memory.)
Q: So, what is the best glide speed and glide ratio?
Ralph: I have a RiteAngle installed. For the most part, I find it to be so
unnecessary, that it is a waste of money. Kevin (the builder) told me it
was
not necessary, but of course I was more than a bit overcautious. In fact, I
was
really hyper, being a new pilot and having learned in a Piper Cherokee that
requires a stall warning light for operation. The reason why it is not
necessary on the RV-9A is that your perspective angle has to be practically
the
equivalent of a >2000fpm climb for the RV-9A to stall. There is absolutely
no
way that you would not notice a stall coming way, way, way ahead of time.
And
the stall itself is harmless, too. The 9A is one incredible calm performer
in
the air.
Take the money and save it for an altrak (from trutrak) altitude hold. 9As
may
not be as fidgety as RV7's, but they are not especially stable. Unstable
sounds
bad, but I think it is the correct term here. It is harmless in this
context.
That is, it is very easy to gain 100'-300' before the loss of speed plane
ever
so slightly buffets down again from the loss of speed. The altitude
oscillations do dampen, but very, very slowly. The 9A just loves to fly.
Anybody who learned in a Piper will find to be the biggest problem realizing
how
long the 9A wants to glide. The flight characteristics seem almost close to
a
motor-glider airplane.
(Now, ground handling is another matter. It is not awful, but it is also
definitely not as easy as that of a Piper.)
Q: Are any aerobatic maneuvers permitted in the 9A? Has anyone tried some?

Hey, sounds like the rest of us. I am working on intersection fairings for the
wheel pants, and I can still do things like that and worse! You are doing fine.
Have fun, and check your work!

Peter,
Check out my website at http://www.toddhoug.com . There's an Autocad file available for download that that came direct from Vans. There's a link on the front page just below the engine picture.

Ivo,
First, thanks for the info of RiteAngle, I'm still not sure if it is a
waste of money. Not all stalls are in straight ahead flight, the ones that
are a problem are when you are heavy, on approach, get distracted the the
tower tells you to do an immediate turn out and go around.
About your flight speeds and ground handling on landing. Have you checked
your air speed indicator? It may be indicating high at low speeds. What is
indicated air speed at stall? This could be why you are seeing 65 mph and
feeling like you are in slow flight. This also could expalin why your 9A
feels so sensitive to rudder input after landing.
