So as you have the correct procedure on the Pedal Nws steering abnormal performance with no Ecam warning let me explain you that not all the malfunctions below V1 or 100 ktos require to abort .

1st . If a low speed leads you to an undesired directional control at 60 knots due the engine torque ,and an system abnormality , the intelligent action is to reduce power on engines. To the level to stop it ? im not really agree because reducing the engine power to zero will lead the speed also and we will continue deeping on that inestability. If you are already on the right side of the runway youll eat the grass and probably destroy the plane. And yes , youll stop it following your procedure "if any malfunction appears before 100 kts ill abort".Simple minds simple consecuences.

2nd The objective is to recover the directional control . As you should know as magnificient holder of CPL license , in airbus theres a transfer of performance from the NWS to the Air Rudder with the speed . Also in boeing.
More speed more effective get the air rudder , the transfer started to produce around between 40 to 60 kts and you can feel it at 80 kts. If you are heavy the transfer is slower if you are lighter ( ferry flight) the transfer is faster.
So you ve to think what is nearer to your objective that is resume safely from that situation.
The captain decided that continue increasing the speed will allow us to recover the control earlier than stopping the plane . And well, he was right, as soon the air rudder got a little performance he centered the plane .
For landing the correct procedure is to land with autobrake MED,full reverse ,try to do not touch the pedals and use the handwheel steering ASAP .
3rd There is documented some accidents due this problem that the captains took the decision .. your decision to abort , and the get out of the runway .. they thought that was because the engine torque push them outside the runway but is not true . Is because the pedal steering has an abnormality on the degree limitation on one of the sides and when you figure out what the hell is going on ,.. they took the instinctive decision to abort .. and lead the plane to a total uncontrolled situation because they apply brakes ON THE PEDALS on a system is not working properly and bye bye.
4th Lets try to speak about aviation and avoid comments like "legal capacity holding pilot license" im not judging you , not your english grammar ,not your vocabulary , and not your knowledge im just posting in a forum about aviation.
