Nescafe - the problem is that PC1/CatA profile is designed for VMC including, I suspect, a well lit helipad if at night.
They had no cultural lighting or assistance other than the landing lamp and if that is your only source of visual reference, pushing the nose down 10 degrees IS going to be very disorientating.
They should have been capable of a vertical climb followed by a gentle acceleration to get to Vmini whilst maintaining the climb.
