            | Testimony : Autonomous Landing |  
            | 12/15/2011 | Bud L. | [Bud mailed the following to other members of his club]: Some of you guys know about my efforts to learn about the Ruby   autopilot.
 This unit has the ability to hold heading and altitude in it's   "assist"
 mode. And in the "autonomous" mode, it will take over the plane a   circle at
 a fixed altitude. I purchased one in the Beta program and installed   it in
 Charlie Conley's Sig LT 40, an electric conversion of that ARF.   After
 several back and forth's with the great Jim Hall of UThere, we got a   set of
 "parameters" working pretty good.
 
 One thing that Ruby claimed   to do, that I had not tested, was that the
 plane on command, will fly the   plane back and land it. This is done all by
 itself. Once you initiate the   command, Ruby will organize a landing
 "solution" and then fly it.  Up until   last sunday, I'd lacked the balls to
 try this. But this Sunday past, Ervin   and I gave it a try.
 
 I clicked the Gear Switch 3 times, Ruby took over.   The plane was upwind
 about 1000 feet and around 400 feet high. Ruby turned   and headed west for a
 downwind leg. The plane went out over the trees. Man, I   wanted to take over
 as the plane went further and further out. But then it   slowly started to
 turn left down wind, right on track for a parallel course   with our runway.
 Ruby was also decending to it's planned 300 foot pattern   altitude.
 
 Then the plane turned left, making a nice right angle turn for   the base
 leg. I could see the propeller changing speeds. Ruby controls   altitude with
 throttle. This is the same method all student pilots learn when   flying the
 "pattern".
 
 Then the plane lined up with another left turn   for final to our runway. The
 prop is speeding up, slowing down, smooth.   Slowly, the plane was coming in
 on final approach. When it was about 100 feet   away and 20 feet high, I took
 over and landed. I have no doubt that Ruby   would have landed the plane.
 
 This is the coolest thing I have ever done   in my whole model experience.
 I've been flying models since 1956. This thing   is an amazing tool. Wow! To
 have a system on board that can fly yur plane for   you has the potential to
 save a lot of situations.
 
 
 To bear   witness, Eric A. watched the whole thing. We did it 2 more
 times just for   fun!
