So actually, you'd need to have pitot/static connected to those instruments as well. You know, another alternative would be to use one of our EMS products. They're less expensive, but you'll still have the panel space issue. You wouldn't use the engine monitor side of things, and you wouldn't get redundancy in the flight instruments. But an EMS-D10 or EMS-D120 can be essentially used as a second "slave" display for an EFIS. All you'd need to connect are power/ground and two DSAB wires.
SkyView's display, which are much thinner than our first generation of products, are designed with exactly this scenario in mind. Unfortunately, they can't be connected with our first generation EFIS products.
