Contact LXNav, as there are obviously a lot of aircraft that require certified instruments, and
they may be pursuing certification so they can also serve that market.

"A lot of aircraft" in this case would be every single glider in the world except US exp. reg gliders, I guess.

Sounds like a strong financial incentive to pursue certification! But, I don't really know what
they think their market is, which could include the US experimental airplanes. They obviously
think there is a decent market that made it worth developing the ADI, as does LX Navigation,
with it's similar "Iris all-in-one":

The main differences between the two that I know about are ..

-The ADI offers an expanded scale at low speeds; the Iris does not (I'm told it's feature they
are working on)
-The ADI Vne can adjust with altitude; the Iris does not have that feature
-The ADI setup is done directly on the instrument; the Iris requires a $200 wifi adapter to
connect to a computer
-The Iris has a built-in backup battery; the ADI does not

I sure hope they launch a 80mm version!

Contact them, tell how much you'd like that! The only difference would be a bigger case and
display, which they already have for the S100, S80, and V80.

Hi,

I've been asked a lot whether the new LXNAV Airdata Indicator has a built-in backup battery. It doesn't. I'm glad because I'm not a fan of built-in backup batteries. They sit in unused for many months and then charge for the glider's main battery - reducing the main battery's ability to power everything else.

I have 2 recommended solutions for making sure the LXNAV Airdata Indicator is available when you need it.
- Use redundant main batteries that you can easily switch between. I use a Battery1/OFF/Battery2 switch in our glider.
- Use a AA battery pack and change the batteries once a year.

The Goddard-Cable-S3-Backup-Sw-1 wiring harness includes a battery pack for 8 AA batteries. It has an ON/OFF/Backup panel-mountable switch for manually switching from main battery power to the AA backup batteries. It is compatible with the LXNAV S3 variometer, LXNAV ADI (Airdata Indicator), and LXNAV G-Meter. I just finished testing it with the ADI and it ran with the backlight at full brightness for 11+ hours. You can see details he

Can also be used with LXNAV S3, and Air-Avionics Air Control display Altimeter.

Craggy Aero S3/ADI Backup Battery Pack Holds 8 AA batteries ON-OFF Panel switch will power the V3/ADI for approx 15 hrs.

Switch has 2 positions Main Glider battery, Backup battery.

There is certainly nothing inherently wrong with backup batteries; I ordered that option for my Garmin G5 PFD. The backup is a lithium battery that holds its charge well. Most importantly, I have vital flight data in the event of a main power failure.
