[left]I've been going crazy for a few days to understand the purpose and use of the two GNS 430 mounted on the Seneca V Carenado. To fly with GPS, one is enough; I tried to fly with the traditional Vor system in Vor, thinking that I could set a route on GPS1 and the next on GPS 2 and then switch but the latter never follows the Vor and, instead of turning, he starts to spin the plane in the round. I have to TURN off the GPS 1 and then the 2 follows the tuned Vor. Is it possible that the two devices are only used as backups of each other in the event of a failure? Am I wrong? Help.
Two GNS 430 GPS units. Lower panel are an old Bendix-King KR87 ADF and a Garmin GTX 327 Transponder/Time unit.
I don't understand. I was referring to the two GNS 430 mounted on the cockpit.
They first had the Bendix, then they added the Garmin.
They both do different functions.
