This from the Airbus operating manual re use of manual thrust and the 100' you referred to.
USE OF A/THR
The pilot should use the A/THR for approaches as it provides accurate speed
control. The pilot will keep hand on the thrust levers so as to be prepared to
react if needed. If for any reason, the speed drops significantly below VAPP,
the pilot may push the thrust levers forward above CLB detent (but below
MCT) till the speed trend arrow indicates an acceleration then bring back the
thrust levers into CLB detent. This is enough to be quickly back on speed.
The pilot should keep in mind, however, that, when below 100 ft AGL, moving
the thrust levers above the CLB detent will result in the A/THR disconnection.
Regarding the fuel/wing icing prob, can't find the ref, but from memory, if the outer tank fuel temp is less than zero (??) and you are descending into an area of high humidity with an outside air temp less 10 (??) you need to transfer fuel to warm it up.
Can any other bus drivers, fill in the blanks on the temps?
