I have also purchased the moving map software, which allows one screen to be put in full-screen map mode. It is easy to become frustrated with the small screen on the Garmin 496. An 8.4" moving map should be a vast improvement. It will display a map with airports and cities and all the goodies of a typical GPS. It will also display rolex replica traffic from the GTX-330 transponder and weather data if I elect to add that feature later.
Currently the map software will only allow me to create a single leg (direct to) flight plan, but they are working on expanding the features.
The displays will also connect to the Garmin SL-30 to display the VOR/Glideslope/Localizer needles. This information is superimposed on the artificial horizon.
I've mentioned connectivity a bit. This is essential if you want your EFIS to be able to present valuable information in a timely manner. The AF3500 will connect to the following:
- Transponder - send encoded altitude data and receive traffic information
- SL-30 NAV/COM - Receive VOR/GS/LOC and send radio frequencies
- Audio panel - Provide audible alerts
- Autopilot - Send navigation information and essentially "fly the plane"
- GPS - Receive global positioning data and download flight plans
