I'm new to the forum and I'm trying to educate myself on what is and what isn't required. I recently purchased my first plane, an experimental Arion Lightning. It's equipped with an MGL Voyager EFIS, Garmin GTX-327, and Garmin 430W. it also has a backup airspeed, altimeter, and second radio. The glass EFIS has all the required gauges, gyros, slip/skid, OAT, etc...
My question is this, what is required testing for IFR use? I know the transponder has to be tested every 24 months, but what about the pitot static system and the Garmin 430W? Does the Garmin 430W require any kind of installation test or inspection? I do have the current nav/data updates.
Thanks,
Curt
