When I started flying my dad's plane with my dad, it was after a pretty long hiatus from General Aviation. Just the way he had things setup, I couldn't really see his iPad well enough and he only has a very ancient Garmin panel GPS that doesn't even have all of the fixes/airports in the database and has no moving map display (think one step above the old IIMorrow LORAN Fly Buddy that I first flew with years earlier). However, his plane is fully IFR capable and has a
Davtron that displays the radial digitally. He never really used it so I'd always reach up and flip it to "FROM" so I could figure out where the hell I was. Since he was never taught on a RMI, he initially kept asking why I wanted it "FROM" when we were heading to a station, but after a while, he understood why I was using it the way I was.
I am definitely a RMI cripple.
