Digital altimeters

Tried of the 57mm Winter altimeter being too inaccurate even after being re-calibrated. Being EXPERIMENTAL, going to look into digital.

Going to look at MGL Vega ASV-1 first as it displays altitude and airspeed. http://www.mglavionics.com/html/vega_color_singles.html

Anyone had experience with this specific make/model?

Even though you are experimental, your airworthiness certificate may be linked to a particular set of basic instruments. Best to check it out before you remove the Winter.
I have used an MGL engine monitoring instrument and thought their quality and documentation was above average. The new instruments have much improved readability.

Why not simply go to Air Avionics?
It is a fully TSO altimeter.

The ACD-57 is about twice the price of the MGL and lacks an ASI.

I just bought a SZD55 with a digital altimeter and a LX9000. First thing I did was put a new Winter 57mm altimeter in it. Main reason was insurance payout is you break it outlanding, second reason was it looks awful and is hard to read.

Just my thoughts.

It may be more expensive than the MGL unit but the fully certified AIR display (including altimeter activation fee) is slightly cheaper than a Winter altimeter - and there is the option of using the display to also control a compatible radio and transponder all from one 57mm hole.

Which would be attractive if you have, as I do, a certified glider. Being certified, however, does not necessarily mean the instrument will be better, more reliable, more accurate, etc. The digital altimeter is, most likely, more reliable and accurate than the certified mechanical altimeter.

Use caution with the Air Avionics transponder if you need ADSB out. Last time I checked their transponder is not capable of a SIL-1 or SIL-3 level output.

Trig will not share communication code with AIRAvionics therefore ACD-57 will not operate a Trig COM or XPDR.

IMO, the 57mm Winter altimeter is a waste of money and panel space.The MGL Vega instruments are said to have good visibility in bright sunlight. I think it is worth a try but first would like to see one powered. Maybe at Oshkosh.

I have one in my Glider and I have them in stock.
