I was told that the artificial 'spring pressure' is actually rigged so that it 'feels' right eg. for RHS, you have more strength pushing the stick LEFT than right, so the resistance to you pushing it left is slightly higher. Very clever.
With no force feedback, there is no need for manual trim (no forces to trim out! Though the aeropplane would still trim for fuel efficiency) - just wondering, does 777 et al with artificial feel routinely use manual trim?
