Question to THS Trim and pitch rate
As i understand the previus posts concerning the nose up THS trim, this is said to be a normal function of Pilot nose up stick input and the computers.
Can somebody explain, how tis is done in relation to the airspeed? I mean, at high airspeed the change of the trim for a given stick input would be slower and at low airspeed it would be higher?
What kind of speed input does the system use, the wrong one from the iced up pitots? If that is the case, in the beginning the actual speed was still high, but the sensed speed was wrong and already much lower.
PNF recogniozes abnormal speed and sets pitch and power, in this case correcting also for the drop of the right wing while trying to get the nose to 5° pitch. The system generates a much greater pitch imput due to the wrong airspeed, which the PF does not recognize right away due to other distractions.
Or does the system generate the same input regardless of airspeed (canīt imageine that would work)?
It would explain the initial maneuvre.
