Remember seeing a comment recently about an option to automatically cross fill the 430s.
I have docn and understand the “manual” form of initiating a cross fill from the flight plan or flight plan catalog on one of the 430s.
My question is: Is there any way to set one 430 to automatically crossfill the other 430 whenever the flight plan in the “top” 430 changes? Would save a lot of button pushing when ATC starts getting creative in Class B airspace!
Also, is this option documented and I’ve gone braindead?
To enable automatic crossfill, go to the AUX section (with the larger knob) then select “Crossfill”. I’m not sitting in front of the plane right now but I believe there’s a setting there which can either be “Manual” (where you must manually initiate the crossfill) or “Automatic” (which automatically cross-fills, whenever the flight plan or direct-to changes). I don’t remember offhand if you need to set both Garmins to “automatic”, or only the ‘transmitting’ one or only the ‘receiving’ one…
That said, I actually prefer manual crossfill. It doesn’t seem to add much to my situational awareness to have the same flight plan displayed on both Garmins (and the Arnav). I prefer to use #1 Garmin for the actual flight plan and #2 for stuff like “direct-to” the destination, so I know the specific distance to the final destination, or “what-if” scenarios, etc. In fact, that’s not too original - before picking up the plane I read on this forum how someone else did the same thing: flight plan in #1, and #2 for "what-if"s.
I suppose if the #1 Garmin just died, it would have been helpful to have the flight-plan pre-programmed in #2. But in that extremely unlikely situation, I’ll just have to be prepared to re-read my clearance notes and re-program the #2 Garmin at that time…
Just my thoughts - obviously we all have our own preferences!
