A 320 Antiskid Nosewheel Sw off prior to push
A question
Does your company SOP require that you switch the Nosewheel Off prior to pushback ? Whats the advantage of leaving the SW on during push, no
Our fleet has older Airbus and newer ones, it was easier to always switch the ASKID/NW off prior to push, no we check, I understand it is for what is written below.
NW STRG DISC........................................................ ...............................................CHECK AS RQRD
In case of pushback (conventional or towbarless), the nosewheel steering selector bypass pin must
be in the tow position. The ECAM ’s NW STRG DISC, or N WHEEL STEERG DISC memos indicate
this to the flight crew.
Could someone explain this further as what I have found in the FCOM is insufficient to understand this 100% ?
Also yes we have to check this below, if anyone has had problems with this and bypass pin faults ? It would be interesting to learn from your experience
CAUTION If NW STRG DISC is not displayed on the ECAM , but the ground crew confirms thatthe steering selector bypass pin is in the towing position, then the pushback must
not be performed. This is to avoid possible nose landing gear damage upon yellow
hydraulic pressurization.To dispatch the aircraft in such a case, Refer to MEL/MI-32-51 Nose Wheel SteeringControl System .
Thanks for your help, gentlemen
