Sluggo, the ASSI is very well thought out for auto-throttle. You have five different airspeeds you can set up depending on flap position, I only use 3. You flip a switch(3-way) that arms it. Then you drop your throttle to zero and that engages it. If you come up with the throttle at all it disengages it and you are back to manual.

It's nerve-wracking at first doing an approach with your throttle stick all the way down but I find it corrects airspeed and sink rate as fast, if not faster than I could do it myself. It also has output for bright LED's that I have mounted like AOA lights on the front strut. Solid green .. to fast .. flashing green - perfect .. flashing red - a little slow .. solid red - go around!

I find when using it, that I land so much slower than I usually do. I have it programmed for 1.3x stall speed. I think all of our natural tendencies are to land a little hot. So it really gets your attention when you look that slow but it really shortens the roll out.

I had one landing where I carried all the way down to a full landing and then never gave it a throttle bump (to disengage). During roll out it throttled up to maintain approach speed and I wound up making an unintended but uneventful touch and go. I just hit the coals once I realized what it was doing.

I did set up the Angle of Attack function as I know that's how most fighter jets do their approaches. But I just set all the warnings and lights based on airspeed alone (it can use either). IMHO a simple pitot tube for airspeed alone would get 90% the job done with this device. Then you don't need to mess with making an AOA sensor. An AOA sensor is less complicated than you think. It is basically two tubes in the air stream, One 45 degrees up and one 45 degrees down. But a pitot tube is VERY, VERY simple. Just a tube stuck into the uninterrupted air stream and possibly a static port 90 degrees to the air stream. And there are a lot of ready made pitot tubes out there (Eagle-Tree, etc...).

Happy Flying,
