Lets have a go!
1. Decreases to zero and then tail goes further up on rotation.
2. At constant RAS, remains with a constant tail up. Decrease speed, tail up and vice versa.
3. At per the climb, depends on airspeed.
4. Do.
5. Tail way up.
6. On flap extension, initially it will stay tail up until the airspeed is reduced. But addition of any TE high lift device will allow a greater AofA and thus higher nose attitude and more tail upon on the vane. However, LE high lift devices allow the nose to be lower for a given AoA, thus airspeed. Thus tail will be lower on extension.
Hower does it all work? I don't know but I think that there is some silicon involved.
