Regarding the nose pitch down on a go-around.
Virgin had an "incident" about two months ago in Hong Kong. A340 entered wind-shear and the crew selected toga at low level (300ft or so). Trouble was that despite full aft on the sidestick the aircraft pitched nose down (sufficiently for the chap in the Dragon Air office (next to r/w?) to see the entire upper surface of the wing!
The a/c reached 70ft before the nose came back up and the a/c climbed away.
Mr Airbus saw this as full vindication of his systems, the operators are not so sure...
