Good grief. Threats of lawsuits would discourage anyone from doing anything. Offering an additional feature does not open the door to lawsuits. This is just a matter of meeting customer needs AND having a competitive product. At the end of the day, the competition will offer these features and more. As a consumer, I will purchase the product that offers the best bang for the buck and provide good service. If someone uses a VFR instrument to fly IFR, and some have done that and some will, it is their choice and responsibility and consequence.
I for one have really enjoyed the excellent customer service and increased functionality of my IFly 720 units. Increased functionality is one of the main reasons I jumped in and purchased my IFly. Planning a flight is so easy and letting it drive my autopilot is just a dream. I am looking forward to seeing what additional offerings and enhancements Adventure Pilot offers and seeing how they compete in the marketplace. Highway in the sky and synthic vision is where the market is so CDI is really not a big issue.
