Does anyone have any experience using the Garmin Aera as a back up when flying IFR? I'm trying to figure out if it is something that could save your life in an emergency? I know it is not legal for navigation, but if you had a full avionics failure, could you use it to fly and approach and get down? Second question. It seems as though the garmin handhelds only have the FAF's and non of the IAF's. How do you go about shooting the approach. Do you have to get vectors on to final? Or is there some way to get the IAF's and IF's loaded in. Even if you have to do it manually. Again, this is in reference to an emergency, where you have lost your primary form of navigation.
