Winter 57mm Altimeter

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.

I am not sure there is an alternative. PZL only do the 80mm type.

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.

Recertification of altimiters is only required if you plan on doing
some IFR flying, not likely in a glider. Just check it against all
the other altitude indicators you have in the modern cockpit, GPS,
Transponder, computer. I find the small altimiter a bit hard to read
at a glanse, so I leave the SN-10 cursor on altitude (double spaced)
on my home page. The small altimiter is just in there to comply with
the requirement to have a pressure altimiter in the cockpit. BTW, I
use the UMA non certified altimiter from Aircraft Spruce for about
$200 bucks.

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 Tim,

Which part of my statement below wasn't true? I love Winter altimeters and
all their products. But the specifications sheet shows that they have less
precision than larger altimeters - which is fine with me and most glider
pilots. I didn't say they were bad, just not as precise. Customers that
understand that are very happy with them - myself included.

Aerosonic makes some really nice 2-1/4 units.

Thank you for all your replies.

My Ventus 2cT is operated under the manufacturers type certificate in
New Zealand, therefore it has to have certified instruments fitted.
The instruments must pass the 2 yearly calibration checks. At 18,000
ft mine is 320 feet out. The calibration table requires it to be +/-
120 ft at that altitude. At sea level to around 10,000 ft it is good
then the calibration goes way out and come right again through 21,000
ft. (I know they are only certified to 20,000 ft).

Thanks again, I think I may just order a new one and get a calibration
check done before I install it in my glider.

the statement "not as precise" and compared to?
