Dual Input Airbus
I've come across a number of pilots who claim that during a late flare from the F/O and in order to save a potentially hard or firm landing, pump the side-stick at short intervals in a way that the dual input doesn't sound.
I have never done it, just keep my finger in the red button hoping i don't have to use it.
my understanding according to the algebraic design, is that it would be necessary to deflect ones sidestick beyond the other's deflected amount, to cause an additional elevator response.
what do you think about this underdog common practice?
