Fistable I have to advise you that I use the FSM only since few days.I have seen in Engine Warning Display that during that take off a green message "T/O" appear, during the climb appear "CLB", for the cruise "CRZ", but during the descend phase doesn't appear the green message "DES" but I read always "CRZ". Why?Thanks in advance.Regards.Donato

Donato,what you see is correct. That "green message" displays the actual thrust limit, and for descent that stays on cruise since you don't need more thrust for descent then you need for cruise.Regards,Markus
