After more than 35 hrs with the A300 I had this happen for the first time (v.1.0.2, pax) NE of WSSS climbing on AP, Nav & Prof engaged. There was a warning "FD1 off" and started falling. I tried to reengage the FD, apply max thrust etc, there was no response, same for flight controls.
What is strange is that it was like hitting a wall -see the lnvmap path screenshots.
Aircraft stress damage is set OFF in msfs settings, other addons running were FSLTL, and simlink.
I repeated the flight everything went OK
