I was under the impression that the the A/THR remained ACTIVE in the MCT detent (ignoring the below 100' and Take off scenarios).
By putting the levers into the MCT detent you are increasing the range that the A/THR may use to an upper limit of MCT, but you are not necessarily commanding MCT.
Having said that I have often used the technique of nudging the levers out of the CLB detent in order to recover the speed and when you do this the power increases rapidly.
Therefore there must be a stage in the approach where the system changes over so that putting the levers into the MCT detent disengages the A/THR and leaves it in the armed mode, thereby commanding an increase in power.
Anybody care to clarify?
