Regarding IAS, if there are people like me (I think there are), who want to design aircraft with thinking about efficiency, performance, safety, and making graceful and soft landings. It is important to have those numbers found out such as what speed will the aircraft stall, what the ideal speed is for touch down. They are about how fast the air flows through the wings not how fast the airplane is moving against ground. Perhaps it is not so important to everybody; I have several years of flight simulator experience so I am very sensitive to speed, attitude, landing rate, cockpit instruments, etc. IAS is great and I very appreciate that you offer it. It would be even more exciting if it can be displayed somewhere inside of the cockpit, perhaps on the RPM screen in the future.
