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.

Winter 57mm Altimeter
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.

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.

Winter 57mm Altimeter
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 tim Please visit the Wings & Wheels website at www.wingsandwheels.com Winter "Paul Remde" wrote in message ...

Winter 57mm Altimeter
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.

Winter 57mm Altimeter
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. |
