Set all controls to DEFAULT profiles - no luck.
I did try again to restart the flight on the runway. Once again it initially set me up at the runway holding point before moving me onto the runway. The flaps again automatically (no input from me) positioned to the T/O position. This means that somewhere in the software it ‘knows’ there is a T/Off position for the flaps. However, if I then move the flaps using the mouse, I am back to the zero or full flap availability, with no T/Off position.
