there's a good chance that same PM will not be able to prevent that tail strike ... and you can forget about your red button in such a time constrained situation.
Simply not true IMO, even if the non flying pilot adds nose down input without pushing red button the actual command output is a blend of the two side stick inputs and the attitude will be reduced, secondly, most left seaters are well aware of problems caused by DUAL INPUTS, thumbs at the ready
,
especially on final.
Now, how do you engage Direct Law in your every day operation ?
For those of us trained on the Airbus, we realize that Direct Law is not required or desired, the beauty of the airplane is that I can yank the stick in whatever direction I want to get the desired effect, regardless of configuration without causing a stall or hurting the airframe, does it work that way on the 744?
