Autopilot
Actually m problem is both vertical and lateral. If you set it on HDG mode to intercept an airway it reacts like a drunken sailor. It will blow thorugh it, turn back, go through it again while at the same time porpoising +/- 100 feet. When you do a vertical speed climb to intercept a pre-set altitude it does the same thing, blows through and then begins its usual porpoising. Why go to Disney when you can treat the wife and kids to the same excitement while in the air.....
I have spent thousands of dollars trying to get it fixed. Although I am not a huge King fan, the KAP 140 worked lije it was on rails vertically and laterally. Excelent intecepting ability in both dimensions. I will try the ALT static to see if that helps the vertical performance.

Back in the goold ole days (when my plane could fly) I found that I could stop the cruise porpoising if I turned off the electric trim.
I would say that perhaps it was a computer interface problem between the old STEC 60-2 and the new Garmin G-500....but I was porpoising before I upgraded. I hold lateral course flawlessly with great cross wind compensation. I have an ancient analog altitude pre-select....by that I mean that I have individual verticle mechanical dials that I use to input Baro, desired altitude, and desired verticle rate. Its primitive, but it works very well. My only other nag is GS Intercept. In my bird, when I set it to intercept the glide slope I expect to hear a klaxon horn followed by an announcement over my intercom to "Dive! Dive! Dive!" cuz she immidiately pushes forward about 15 degrees nose down. Fortunately, my thumb never strays too far from my Autopilot Disconnect button when I am below 3k I have no doubt that my issues are some adjustment that needs tweaking. But for now...I have other priorities. Cole |

I hope by the time I purchase one for my Skymaster, the problem will be determined. Considering the amount of the purchase and to have installed, I think I should be able to at least track a course and hold altitude in smooth air. I can understand if the porpose problem existed in turbulent air.
