What is the thrust angle relative to the horizontal at take off?
Google suggests that the A380 engines produce a total thrust of 130,000 kg roughly. If the thrust angle was 20 degrees the vertical component would be
130,000 * sin(20) = 44,000Kg
The aircraft max TOW is around 560,000kg so the vertical component of thrust is about 10% of the total force required to lift off.
