If the fly-by-wire system is able to keep the aircraft safe by remaining inside an operational envelope (not too fast, not too slow, limits on bank angle and angle of attack etc.) why can't the same be done with aircraft attitude when close to the ground.
There is an envelope outside of which either the tail will scrape, or the wingtips will scrape given the aircraft's attitude and height above the ground. Why can't these limits be protected via the flight control software/computers?
