Is it powered direct or by another instrument?
Did you install a dedicated fuse?
Did you install a dedicated off/on switch or is it slaved?
Do you use a dedicated GPS antennae or split with another instrument..
Do you ever have the in-flight need to turn it off?
If you have both, why would you fly with one on and not the other?
If necessary, how is the Trig -2X and the TN-72 software updated?

Thanks for your reply.

I refuse to install flarm, because I consider that company to be actively obstructing the adoption of adsb in gliders, by diverting money better spent on adsb, and by not allowing flarm traffic displays to accept non-flarm-format inputs. My glider has a Trig 22 and TN72 and a scout adsb-in sending data to the foreflight on my kneepad iphone.
