Thanks Larry. I have been reading up on the Skyview sys which I have for my panel. I wasn't aware of all the capabilities of the system. You mentioned that you had helped install a Skyview sys w/ AoA in a friend's RV-10. I haven't completely digested all the features of the Skyview sys. Does the AoA require an additional component or is it a built-in feature of the system? If it is part of the system, I may just purchase the static/AoA probe and sell the Advanced Flight AoA package. Decisions, decisions. Pete
