Flying the DA 62 on a long haul flight (trying to get my saddle sore achievement) and the autopilot disengages and I can not reengage it It will reengage for about 10 seconds then drop off again.
7500 set altitude, NAV ON, about 2.5 hours into the flight.
I have experienced this before on a previous flight, but do not remember which aircraft/gps system.
Thanks.
Dave
