The system is redesigned now with the introduction of the RSEP modification.
Indeed, as specified in the FCTM the speeds after RSEP modification are F5-170, F10-160 , as were before deciding to increase them as a result of uncommanded rudder case analisys.
We tend to use F5-180 and F10-160 ,due to ATC requirement to keep 160 kt to 4 NM.
