The VSPD in pitch servo configuration was changed recently‚ following day both PFD/MFD was displaying "DSAB Network Configuration Error". Ack button or recycling power was not clearing the error. The engine RPM was also showing 1 third of what it should be.
An AME looked into it and noticed that all the values seems to have gone back to factory defaults. For instance the engine is configured as a 6 cylinder instead of the 4 cylinder lycoming that is installed. We are checking if all the old configuration were downloaded or saved earlier.
I am puzzled what could have caused this issue. Could a bad internal battery wipe out all stored configurations?
