FWIW
There has been a recent thead on this list concerning instruments
manufactured outside the USA. My recent experience might be of interest
to some list followers.
In preparation for FAA inspection of my RV-6A and IFR certification, I
had my altimeter-encoder-transponder combination checked at the local
avionics repair station. I purchased the altimeter from Van's and is
part number;BG-3B. It carries the brand name of Falcon Gauge,Wultrad,
Inc. It is manufactured in China.
The testing procedure takes the altimeter to pressure altitudes from
-1000 feet to 20000 feet at incriments of 500 feet through 2000 feet,
1000 feet through 4000 feet and 2000 feet through 20000 feet and notes
the error at each altitude. The results were zero error through 4000
feet and well within the required tolerances through 20000 feet.
The technician who conducted tests commented that he tests about two
altimeters every day. He said that this altimeter performed at least as
well as the name brands that he tests.
Regards,
Richard Dudley

But for how long? And what are indications of increasing inaccuracies,
if there is a gradual degradation of the units?

That sound like a question that could be applied to any item . . .
TSO'd or NOT!
IMHO . . . if it's good today, under "normal" service it will probably
be good tomorrow?!

--> AeroElectric-List message posted by: Gilles Thesee <Gilles.Thesee@ac-grenoble.fr>
Hi Bob and all,
This is a question about an AIM electric AI. The Horizon runs as soon as
the master is ON.
A buddy professional pilot told us that we should cage the gyro before
starting the engine. This is supposed to prevent damage to the gyro due
to the rapid erection on power up.
Is that facts or ..?
What is your opinion ?
Thanks,
Gilles Thesee

Personal experience - purchased a Chinese AI and DG, knock-off look-alike of
RC Allen. AI never erected past 45 deg first time I ever fired it up -
would cost $250 to repair (which was just a little less than what I paid for
it). Ditched it and got a real RC Allen and have 260 trouble free hours.
The Chinese DG has not actually failed - but it clearly is not up to the
standards we are used to. Just about useless - would certainly never rely on
it. There may be some good Chinese instruments but these were not them.

Hi Ed,
I was wondering - how much does the el. (12V) RC Allen AI draw?

Sorry, Rumen, I jumped in the thread without realizing it was about Chinese
Electric gyros - this was vacuum driven.
