The default KAP 140 autopilot has a number of bugs. I have seen several discussions elsewhere about mods and corrections, but here, I’m hoping to compile a list of the issues as a bug. They should be relatively easy to fix, as most or all of them are not present in other autopilots that already exist, such as the G1000. There is a lot of attention devoted to improving the G1000, which is important, but I fear that this device is not getting the same focus. This autopilot is particularly important because it is used by a number of a third party planes, including my beloved Milviz 310.
These are the issues I personally confirmed today:
-
When in alt hold mode, if a different altitude is selected, pressing either up or dn puts the aircraft into an aggressive climb or descent towards the new altitude. On the real system, doing that should change the assigned altitude slightly.
-
Engaging the autopilot puts it into ROL and VS modes, but neither mode works properly when the autopilot is engaged. The ROL mode brings the wings level rather than holding the roll angle. The VS mode either goes to zero vertical speed or the previously set vertical speed, but that can be inconsistent. It should instead hold the vertical speed at the time of engagement. These bugs make the autopilot very difficult to engage during any type of climb or descent.
I’m aware that there are some mods that try to fix these and other issues, but this is a pretty basic piece of core functionality. Again, the default G1000, for all its faults, doesn’t have these issues specifically. A fairly quick pass on this system would go a long way to helping all the aircraft that use it.
Thanks!
