I'm working with A320 and XFMC with correct conf file...recognized by FMC. All works fine, without activating the AP of the XFMC, but after flying some minutes (10min...) a flightplan the LEGS page and the complete flightplan gets empty.
Anyone know why? It is like if you reset the XFMC. There's no origin, no destination, no flightplan....
Thanks in advance.
