It is obvious you are not taking it very well that you were not aware of this procedure. You are trying to clutch at the slightest evidence no matter how ridiculous that the procedure was crap. Kindly examine the first line of the procedure.
"During the approach, with the A/THR active, Airbus recommended to set the thrust levers above the CL detent (but below the MCT detent), in exceptional circumstances, if the speed significantly dropped below VAPP."
When speed significantly dropps below 100', you simply go around. Even in your airline. Any pilot who tried to do anything else deserves your favourite word crap.
However this procedure did not come out of thin air. DSC-22-30-90P5/14 is quoted below:
The thrust levers provide the flight crew with an immediate increase of thrust when both thrust levers are pushed above the CL detent (two engines) or the active thrust lever above the MCT detent (one engine operative).
Last but not least United Airlines manual revision shows this FCB.
Thank you.
