If you were experiencing the following problem, we have an update on this issue, and a solution for you to try out:
To recap, some customers have been experiencing momentary GPS data dropouts from 3rd party GPS devices that can feed a D10/D100 series-based autopilot. When this happens, and the autopilot is following the GPS through either the NAV or TRK modes, the autopilot decides that the GPS has gone away. This, in turn causes the autopilot to revert to heading mode. Some customers experience this routinely, as often as every few minutes.
We've had a hard time characterizing the exact nature of the problem, and getting a smoking gun of the problem happening in action is pretty difficult for affected customers to do. So, while we aren't 100% sure that this attempted fix will work, we're fairly confident in it.
Below is a "beta" version of D10/D100 series firmware that is exactly the same as 5.4.3, except for that it includes an attempt to fix the above undesirable behavior. It has no new features, and it does not fix any other problems. This software is not considered an official release. Though it is considered stable, it has not received the full set of release testing that would normally be performed on a firmware release.
PLEASE tell us if this firmware fixes the dropout issue for you. We'd love to get both positive and negative confirmations from everyone that installs it. A post here or an email to support at dynonavionics dot com are the best ways to let us know how it works for you.
