When Boeing introduced the B737-400 they also included a tail bumper. Why didn’t Airbus put something in place as well when introducing the A321?
So it's not true then; the pilot can take an AB outside its comfort zone. A RAD ALT on the tail link into the pitch computer and a filter than resists further pilot input. Being a Boeing man I thought that's what all these Toulouse electrons was about. Don't let the pilot bend the a/c. There have been other demonstrations of this myth being false; here's another.
But I do ask the question as a technician, not a pilot: why not have proximity sensors in the tail linked to pitch channel; both take off and landing?
