We're considering adding a GNS 430 to our panel. The hight of the
display is rather small, and Garmin tells me that the position of the
plane is fixed in the center, and can not be relocated to the bottom
of the display, which would allow the entire display, rather than only
the top 1/2 of the display to show airspace ahead. I think that in the
enroute mode, it would be nice to be able to use the entire display
for airspace ahead. But I have not actually flown with this unit, and
I'd like to know if those of you who have used it find that the
display of airspace ahead is adequate and easily visable. I realize
that zooming out can increase the area displayed, but at the expense
of detail. Thanks for any info you can provide.

You can download the simulator he
