What is the effect of an aft shift of the centre of gravity on (1) static longitudinal stability and (2) the required control deflection for a given pitch change?

1) One of the requirements for positive dynamic stability is:

2) Rolling is the rotation of the aeroplane about the:

3) Rotation about the lateral axis is called:

4) The pitch angle is defined as the angle between the:
