I heard this from a former SEA colleague about this quirk in flying the scare bus. He had transitioned to the T7 and was discussing or rather giving some tips about his experience to some new A330 drivers.....he cautioned against " fighting the controls " via the side stick especially pitching motions in gusty weather when close to touchdown. According to him, if you fight the controls with pitch down inputs, the autotrim will trim down and when this cuts out below 100 ft RA as the flight control law transitions to flare law, you lose a lot of pitch authority to flare and there it goes into a crunch unless you're fast enough to take momentarily take the thrust levers out of climb detent and back to get a boost of raw power to cushion the thump. And only if there is sufficiently runway to play around with........the temporary power boost can be considerable if one is not quick enough to " retard "
