I'm looking at the following components:
GTN 625 with separate GNC 255 COM/NAV
GDU 460/470 (one each)
G5
Looking through the drawings, the GNC 255 has one serial port to communicate with the rest of the system; I suppose it should be connected to the primary GDU? The drawings show a choice of any of the GPS-enabled items having a potential link to the radio. Is one the best?
Also, for the NAV side of the GNC 255.... Does the 460 or 470 have the ability to show DME, ILS/VOR, etc? How is the NAV radio data read back to the G3X system for use inflight? I think that it may not, but wanted to ask.... is the only way to get this done with a GTN650 having built in Nav/Com and more serial channels?
I see in the G5 docs that the VOR heading can be set with the G5 via a serial link, so I assume the same is true if the serial link is taken to the GDU 460 instead. That also implies the radio will send the VOR error for display back to the G5 or GDU 460 accordingly. Does that also apply for ILS? DME?
