You have to read the manual to discover the vertical speed indicator can be used as a vario
(using electronic Total Energy compensation - no probe), or as a standard, uncompensated VSI.
No audio, but probably at least adequate as a backup to the primary vario. That makes it a
3-in-one combo: ASI, ALT, Vario. That's good news for small panels, and a lot cheaper, too.

Looks like an excellent concept but does it have any sort of approval? I can't see any mention one way or the other on the LX Nav website or in the manual.

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.

I may be wrong but I don't believe any of the Winter Instruments we see in gliders have ETSO certification.

They are ETSO, and they come new with a Form 1.

"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":

http://www.lxnavigation.com/iris-series/

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

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 here:

Good Soaring,

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.

No ETSO for the ADI at this time. I would say OK for experimental aircraft.

The Air Avionic ACD has a ETSO Altimeter and also controls Transponder/Transceiver.
