LXNAV introduces New ADI Air Data Indicator

[Richard Pfiffner[_2_]]

LXNAV

Indicates airspeed, altitude and vertical speed with an integrated high precision digital pressure sensors. The unit has standard dimension of 57 mm diameter. Not TSO.

Many features see

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.

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.

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

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 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.
