I fear that the PF tried to initiate the GA by simply pressing the TOGA switches and doing nothing else. As nitpicker comments certain things have to happen.
1. Power must come up. If it doesn't then you push those sticks up (Boeing) towards the panel.
2. The nose must rotate up - be it 5, 7, 10 degrees its got to go up. If it doesn't then make it do so, by taking out the autopilot.
But then all this would be moot if, at the onset of center line deviation the autopilot was disconnect and manual control was taken.
