I fly a bizjet with old avionics, this could not have happened on my plane.
before you line up on the runway, you would have already pushed the TO/GA button and you have a 10 degrees nose up flight director, generaly associated with LNAV or Heading mode. No autothrottle.
When you hear "rotate", the procedure is to rotate to a 17 to 20 degrees nose up attitude and to target a speed of 160knt, then ask for FLC.
when the PNF select FLC, the FD will come up to match your attitude.
So my question is :
On a 777, when you line up with your PFD ready for the departure, does the FD gives you a pitch up of 10 degrees or does it stay at 2 or 3 degrees and goes up automaticly at the selected Vrotate ?
