Hi Jack. No, different problem I think. When already in CRZ the FMS shows a green speed/mach number. e.g. Managed speed is, say .80. I want to CRZ at .84, but as it is in green, I can't change it to the higher mach number. It won't let me. If I 'use 'select' mode on the FCU, I can CRZ faster, but if I then revert to 'managed' mode, the speed reverts to the green speed as shown in the FMS. BUT, I'll look at this again tonight.....perhaps when I select the FCU speed, the FMS DOES go blue....this I will check ....apprec your comment
