In reply to the below, its easy to work out the answer, check the C of G at
http://www.yakuk.com/Yak52TW_W <http://www.yakuk.com/Yak52TW_W&B.xls> &B.xls
(excel spread sheet) this calculation chart prepared by Steve Dalton. The
YAK 52 and YAK 50 C of G aft limits are 27% MAC. So the design office with
100's of personal say. I don't know if aerostar increased the tail plane
area, lengthened the fuselage or anything else when the declared the aft
limit now to be 31% The problem they have was putting the main fuel behind
the main spar. In the YAK 52TD we put the fuel in front of the main spar
approx on the C of G so loading with fuel does not cause huge shifts, in
fact the lightening exercise we did placed the c of g a little to far FWD in
the 52TD, all we do now is to position, battery, radio and one AI converter
in the rear to give the original C of g positions. We can also configure the
a/c for P1 back seat so putting a passenger in does not upset loading, this
is a far better option for aerobatics.
Hey, I have a question for the TW owners. Is it true that spins are
not recommended with someone in the back seat? That this was never
tested at the factory?

Yes folks, TFR's are scary since they can "pop-up" at any
time, especially during a busy campaign season. However,
many pilots in the land of Hanging Chad face a real menace:
Das Hanger Nazis. This last weekend I heard another Tale of
Terror from a fellow warbirder at a local airshow.
He hangers in SW Florida. The current airport admin entered
his (and others) hanger without his knowledge...looking for
signs of maintenance which is limited to a small partial
shade hanger located across the field. No more than 6 qts of
oil can be in the hanger, no wooden work bench, no spray
paint, etc. They even got into his cabin for examination of
paperwork, and opened the cowlings on the engines looking
for fresh signs of maintenance, and non-STC'd mods,
whatever.
Since we now know that the 911 terrorists lived and trained
in FLA, local airport authorities have taken such steps to
protect the Homeland from the Pilot Menance. They expect
local FBO's to help report crimes like "performing
maintenance in a hanger without paying the FBO's mechanic".
Dumping sumped fuel on the airport surface can result in a
$50K fine but it's OK for Phosphate Mines to ignore their
runoff...something about campaign contributions?

Hello folks,
I wonder if anyone has an answer for the following:
I've got two simple questions that may or may not have simple answers
regarding a Yak 52's carb.
I know the main metering adjustment screw
works by turning it clockwise to richen the mixture and counterclockwise
to lean the mixture, but does the idle mixture adjustment screw work the
same way?
Also does anyone happen to know at what percent power the carb switches
from idle mixture control to the main mixture control?
Best regards,
Ross Bausone

Hi again, group,
We are wondering about our power settings for our Yak 52
Is there a "standard" list of Military Power, cruise 1, cruise 2, etc settings
for percent RPM and Manifold Pressure?
We are in doubt about our settings placard.
Best regards,
Ross Bausone

I was reading some financial stories and stumbled across this one. http://www.forbes.com/personalfinance/2004/10/12/cx_da_1012topnews.html?partnernetscape
Its the new tax laws that were recently approved in congress dressed up as a tax
cut. But towards the end of the story they describe how they plan to make up
the revenue shortfall. The item of interest to this list is an increase in the
tax on aviation fuel! Just what the aviation industry needs most.

M14 Carburettor/Power Settings
In reply to Ross's letter:
=D8 Do not attempt to set up the carburettor without a manual. It is a very
sophisticated carburettor and each adjustment not only affects other adjustments,
but each is only valid for a certain rpm range.
=D8 There are five power settings:
o Take-off 360-hp (-2%)
o Nominal I 290-hp -2%
o Nominal II 240-hp -2%
o Cruise 1 180-hp
o Cruise 2 144-hp
=D8 The figures are given in the front of your logbook, together with the rpm/boost
settings and the actual figures for that engine.

Unbelievable! I'll bet some good aviation oriented attorney would jump all
over the unauthorized/no-notice entry thing, regardless of what it may say
in the lease agreement. That would be like someone renting an apartment or
any domain for that matter and the lessor arbitrarily entering the property
without prior notification to the lessee. What would happen if the lessee
happened to call the police and report a breaking and entering? To take it
one step further, what would have happened if the lessee had whacked the
perpetrator over the head because he/she wanted to protect his property?
Protecting his/her property is a "take appropriate action first, then ask
questions later".
I'll get down off my pedestal now! This just ticks me off!
Dennis

HI all
This might sound like a stupid question, but are the
power settings influenced by altitude?
My home airfield is 5400 ft asl. On an average day the
ambient pressure is probably 600 mm Hg. The book
figures for power settings seem to assume ambient
pressure for normal sea level conditions.
At the moment I tend to use 600 mm / 64% as my cruise
setting. This gives an indicated airspeed of 200-210
km/hr at 7000 / 7500 ft asl. Is this correct, or
should I be using 735 mm (would be about full
throttle)?
Jorgen, what do you use out at FAWB?

Hi Mike
Been running back & forth to FAVV a few times lately - there at 7000,
back at 7500.
At 7000 I can't get 735mm, usually get around 630 wide open. So I use
either wide open or 600mm, and pitch all the way back, around 64% (Think
my low pitch needs adjustment, can't get lower).
On Sunday I got (wheels off to wheels on):
FAWB - FAVV 69NM 33 minutes 7000ft 630mm 64%
FAVV - FAWB 64NM 32 Minutes 7500ft 600mm 64%
Used a total of 69 litres of fuel, for 01h05 flying time.
Your timing is good. I don't normally measure this, but did on Sunday
just out of interest.
Be nice to put a bigger blower on and get sea level performance up here.
Are you based at FAGC?
Jorgen
