Autothrust time constannt & Declining Airspeeds
Here is a first clue about the A/THR reaction time (~4 sec.) in managed speed mode, for a given stimulis (airspeed profile) and for an A340 in approach though. In the case of Air Caraïbe the CAS dropped from 273 kts to 85 kts very rapidly, in other cases, fluctuations are superposed to the decreasing trend.
