I see the glass, all in one engine monitors and flight instruments, for sale by the various aircraft supply catalogs, but there is no mention of FAA PMA, or STC in the ads. Are those strictly for home builts and experimentals, or do some come with STCs for particular aircraft. That would be one way to solve the limited avionics and flight instrument space in the older Cessnas. Does anyone know (I'm sure Rick does) how these can legally be installed in the 175?
