I have a Mooney Bravo, and I have done a few things that are for nothing more than the sake of its cool (LED lights). However, I have seen videos over the year of the Alpha Systems AOA, and how it allows you to fly your airplane in a very efficient and practical way. Last year at Oshkosh, I happened upon Alpha Systems’ booth and spoke with Mark Korin, the owner and developer of the Alpha Systems AOA. I purchased the system and had it installed over the past few months while the plane is in for annual. Here’s what I have to say. I love it! If nothing more than the fact that it has audio cues to make you aware of trends in your airplane’s airspeed. It shows you your best lift over drag on the approach and gives you great information, visual, and oral, on just how much lift you have. It’s not cheap. Plan on about $4000 for the system and another $4000 to install it, but it is a great tool. I installed the right seat, second position option, so us to have that information flying from the right seat. I feel is valuable and I do not regret spending the money. If you are thinking about it or have any questions about the system, just reach out to me and I would be more than happy to discuss my findings on it Sent from my iPhone using Tapatalk
