Century ll B Posted January 11, 2020 Report Share Posted January 11, 2020 I have century Il B in my 78 201 and the auto pilot rolls back and forth 7 - 10 degrees when engaged. Has anyone experienced this issue, if so any solutions Thanks Mark Quote Link to comment Share on other sites More sharing options...
carusoam Posted January 11, 2020 Report Share Posted January 11, 2020 Welcome aboard Mark... What is Kearsch? And why is your screen name Century II B? You can always start over, or change what you wrote, if you like... Have you used the search function to look this up at all? Stand by to see what answers may be coming your way... we have a few AP knowledgeable people around here... they just might not know what you are looking for without opening the thread... ya know?

adverseyaw Posted January 16, 2020 Report Share Posted January 16, 2020 Is this a recent change in the way the autopilot performs? My IIB wandered a bit and my avionics shop ran adjusted a few pots on the controller to dial up/down the gain on the various signals inside the unit. The adjustment process is fairly simple and is described in the maintenance manual. There could also be a component failure happening (in the autopilot or the DG/HSI encoder) but you can at least try the adjustment first. When I had my IIB fully adjusted, it would still wander a few degrees after a turn or encountering a crosswind in cruise. It usually took 10-20 miles for the oscillation to settle down. Like carusoam mentions, there are other threads on this. 2 Quote Link to comment Share on other sites More sharing options...
steingar Posted January 16, 2020 Report Share Posted January 16, 2020 I thought maybe Kearsch was a bastardization of Kirsch, a liquor you might drink after finding your autopilot on the fritz. 1 Quote Link to comment Share on other sites More sharing options...

jetdriven Posted January 17, 2020 Report Share Posted January 17, 2020 Is it fast oscillation , or is it slow. Quote Link to comment Share on other sites More sharing options...
