this isn't true..and I don't think Winter would be very pleased to know they
are being misrepresented...the "certified" Winter altimeters (Winter also
does make a variety of instruments without EASA approval) meet and are
certified to EASA standards TS 10.220/48 like and accepted the same as US
TSO and can be used in certified aircraft....there were some modifications
made in recent years to these altimeters to improve performance in that some
older version did have occasionally an issue with jumping a cog in the
barometric adjustment gears but even the older versions can be repaired and
calibrated back to the required specifications.
You can send your altimeter back to the manufacturer (I also accept winter
instruments here that I ship for my customers to the manufacturer for
repairs) for update, overhaul and re-calibration if needed and you'll find
they are very good with their support and service and always stand behind
every product they produce. Winter does recommend periodic re-calibration,
just like nearly all altimeter manufacturers

Hi,

What was the criteria for the failure of the check? The Winter altimeters
are not, and cannot be as accurate as larger altimeters. Winter doesn't
claim they are. But they are fine for most glider pilots. I sometimes
get complaints about them from instrument rated power pilots, who expect
them to perform like a larger altimeter.

You can see the specifications on my web site he
http://www.cumulus-soaring.com/winter.htm#W-4555

Or perhaps the unit just needs repair at Winter. They support their
products very well. A repair would cost much less than a new unit.

I fly with 2 Winter 4555 altimeters in our DG-1000 and I'm happy with
them. But I suppose I'm biased because I sell and support them.

In the last year I heard of a new brand that offers 57mm altimeters for
use in certificated aircraft. I inquired and found that they cost over
$3000!!!! Wow! That is the only other option I am aware of. I don't
remember the brand name, but I believe United Instruments now offers them
as well for even more money.

Best Regards,

I have just had my Winter 57mm altimeter fail it's instrument check.
From what I can ascertain, this is not all that uncommon. Does anyone
have any ideas or suggestions of a suitable 2-1/4" alternative.
