I'm also with Skittles on this one.
The aircraft was planted by the F/O and we had an ACARS reading of 2.1G. Subsequently the Engineers determined that it was only 1.7G because the aircraft looked at the difference between the positive and negative 'G' - apparently.
During the taxi in I was in shock to be honest, as was the F/O. The poor F/O was actually in tears at the gate.
I had thought that there must be damage although a post flight walkround revealed nothing to me. We nightstopped for the Engineer to do inspections which revealed nothing amiss.
Anyway, how any crew could think that 3.5G is nothing to worry about is beyond me.
By the way I was dragged into the office and given a dressing down about allowing an F/O to carry out a night landing off an NPA. Maybe they were correct, although it had never happened before or since.
