PT20J Posted March 20 Report Posted March 20 A while back (I believe it was update 20.30) Garmin made the option available to delete the self test screen. The self test is designed for analog equipment to make sure that the attached navigation instruments are functioning properly. (This is the screen that shows half deflection of needles and 135 deg RMI, etc). The self test isn't necessary if the GTN Xi is interfaced to Garmin PFDs because the interface is all serial/digital and it either works or doesn't and if it's not working the PFD will display an error. If you have a Garmin panel and wish to delete the self test, you can do so in configuration mode. The GTN Xi maintenance manual (available on Garmin's website) Appendix A contains a form that lists all the configuration options. If you don't have a current one, it's not a bad idea to go into configuration mode (described in the manual) and record all the current settings. That way, you have a record of how it's set up just in case the configuration gets messed up during maintenance. Dealers are supposed to verify all the settings before and after a software update. But, stuff happens. Quote
Marc_B Posted March 22 Report Posted March 22 Interesting! I haven’t heard this before and I’ve always treated the self test check as I would with any instruments especially on an IFR flight. Quote
