Interesting.
I get the GG mail where numerous post are attached. I dont get them
individually. I checked every volume
from Sat AM to todays and never saw it. If you get the post
individually, maybe they're not moderated or
should i say "censored".

Bill,
Can I get a copy of your performance chart (card)?
I've also taken off from the Grand Canyon at over 1600 lb weight and
climbed out very well. I took off once on a grass strip at 5000 ft msl
(Johnson Creek, ID) at around 40F and 1684+ lb weight and had no
problem. Got off the ground in about 2000 ft. as I recall. My prop
pitch is 63".

Good question. Because there is no official POH performace reference
for an O320 AA1X, I created my own charts. Our plane has a 62 inch pitch
prop. I don't remember what the stock Cheetah prop pitch is, but the
closest I could get (and I figured it would be close enough) was to scab
the % power data out of my old Cheetah manual which I converted to an
easy to read card I carry in the cockpit. That's what I use, plus the
old standard of full rich to 5000' DA (conveniently displayed on my EI
Super Clock), and thereafter lean for all full throttle operations.
Under 5000' DA I refer to the scabbed Cheetah data for leaning below 75%
RPM settings. I think it works.
As for the rest of the data, like takeoff distances, cruise speeds and
fuel flows, and rates of climb, being an obsessive former flight test
engineer I undertood a mini program using a combination of many flights
and accepted formulas to create what has been a reliable reference card
which presents all this information. Takeoff distance for weights from
1450# to 1684# and DA's from sea level to 8000' are in a table. Cruise
speeds and fuel flows are listed for DA's from 4000' to 15000' and rates
of climb for the entire weight range are listed from DA's of sea level
to 15000'. I have added a safety buffer to the calculations where it
seemed prudent and have had not had any surprises. Last year my wife
and I departed the Grand Canyon airport early in the morning. For the
reported conditions we lifted off and climbed out very close to the
performance predicted on the card. It was the first time we had the
airplane in a truly high DA situation at max weight and, at least on
that day, it did a good job..

No POH for an O320 in an AA1x: OK Bill, tell us, what do you do for
percent power in your O320 powered 2-seater? If you had a JPI 800, it
would display percent power for you. In fact, if you let my put in a
JPI 830, you will have, at all times, in one unit:
RPM, Manifold Pressure, EGT/CHT, Oil Temp, Oil Pressure, OAT, Volts,
Carb Temp, % power, EGT delta, Fuel Flow, Gallons used, Gallons
remaining, AND miles per gallon. And it takes up a lot less space than
you are currently occupying.

| Subject: | Fwd: My plane is slower than my prop |
A customer sent me this from GG.
I have two customers with late AG5Bs. The 2004 will not turn 2700 rpm at
5,000 feet with a 63 inch pitch prop. The 2005 will turn 2800 rpm. The
planes are very similarly equipped. The 2004 has two 430s, the other a
430 and a 530. The 2004 weighs 1550, the 2005 weighs 1574. They both ha
ve 63 inch pitch props.
I have been all over the 2004 to find out where the difference is. My fir
st thought was that the carb was not set up right. I removed the carb, se
nt it to LyCon, had it checked, then reinstalled it so that I was sure the
throttle opened all the way. No change. Then I removed the air filter.
A little change, maybe 25 rpm, but not significant. I then completely re
-rigged the plane, put my 65-63-61 prop on it and I could just barely get
to 2700 straight and level.
I've got a lot of hours in both of them. One is significantly faster. I
can't figure out why.
On a similar note, I have a customer with a 76 that's been wrecked a coupl
e of times, patched back together, and is not straight at all. It will ru
n way over red line with a 65 inch prop and trues all day at 144 knots and
2650 rpm. He's getting the Jaguar cowling in a couple of months. We'll
see then.

I'd question whether a stock AG-5B (with a 65" pitch prop) will turn 2700
rpm in level flight, full throttle at 8000 msl. If not, it won't do 143
kts cruise speed.

I don't know without doing some more flying. I suspect it would be
close to 140 kts. The weather is to crapy to check it out today!
