Activating the nose-wheel steering inhibits braking on the central bogie, becoming completely ineffective past 20° of steering.
Another little "gotcha". Presumably a good reason for this in normal ops...but when the proverbial hits the fan surely you want all stopping capabilities..... usually if you are swerving to avoid something that would be an indication you need a large stopping force....
A lot of these Airbus features which generally are pretty good seem to have major ramifications at rather inconvenient times.
A couple of caveats before the usual B vs A debate: Neither manufacturer is immune from these "gotchas", and is this incident clearly a few protocols were overlooked and lastly reducing the thrust might have seemed like a good idea too.
