The avherald article doesn’t make sense. At the rotate call the PF looks solely outside whilst rotating until the runway / horizon starts to disappear then transfers onto the FD. At this point the pitch attitude will be around 7-10 degrees, which is the single engine climb out range, 2 engine about 12-15 depending how much improved climb. So they would have had to pitch forward again to follow the FD which would be totally counter intuitive unless you encountered severe windshear. If the FD was commanding a pitch down you would instinctively check the airspeed. If it was still increasing you wouldn’t push forward. If it was decreasing then either windshear or airspeed unreliable (like the lufthansa cargo 777 crew who had exactly this recently and did a great job recognising and recovering from it). If there’s any doubt then 10 degrees pitch and 85 % N1 will achieve a safe climb out. And as PM if the PF started pushing forward it would feel horrible and immediate intervention would surely occur?
