So he wasn't right then.
I can't see the TFU but I doubt it has flight crew recommendations for SOPs.
How does the NWS/Antiskid Switch off effect 5GC then, it doesn't just any form of MSG. It only prevents inadvertent inputs from pedals or tiller. Another issue.
If the micro switch fails you get powered actuators. Fail safe to null. I have stripped down many a steering cylinder!!
If you are towing without hydraulic pressure as you are suggesting you require a tow-bar-less tractor or Shear pin-less tow bar. An engine start on stand should be conducted to confirm adequate brake pressure if elec pump u/s and on a shear type tow bar.
(off point, sorry)
