I have a question. I fly a C-172RG here at the flight school. The #1 nav went inop not too long ago (uses an HSI), and is placered IAW 91.213. Is the HSI, coupled with the GPS considered inop also? It seems to work (The HSI and GPS). When the HSI is selected to the #1 Nav, that is when the flag appears.
