Before the three wheels touched the ground?
Thanks
Marcio,
At the flare at least one of the TLs (the left one) was brought to idle.
At the same time the other one either was brought to idle but its TLA reading remained in CLB or remained also phisically at CLB.
In such a situation be the wheels on the ground or not the AutoThrust will rely in just one engine to keep assigned speed. Then the right engine will show a thrust increase.
I don't know whether this thrust increase should be limited by the right TLA reading or not in this case.
