A321 - Useless A/THR or v2500 lag
Apart from disconnecting the A/THR or adding a few knots to allow for it, does anyone have any operating suggestions for the A321 in windshear? Anyone have any good techniques to prevent the THR lag?
Flying an approach the other day we had significant undershoot shear. With the loss of airspeed I was surprised by the excessive sink rate which occurred (1600fpm), and the extreme lack of A/THR and/or engine response.
Disconnecting the ATHR we recovered the situation. Truly surprised we did not receive a reactive windshear warning.
It just seemed to lag as the V2500 spooled to its higher N1 to achieve the trust/EPR required.
