m&v, checkout Fcom 3.03.06 P9 'Climb, Cruise, Descent Speed Preselection'. It says there that you..'may preselect GD speed on the PERF CLB page.. for close in turn or close in alt constraint'. Equally, of course, you could always hit EXPEDITE once the flaps are running in to achieve the same result. Are you saying that it is in your SOPs to enter GD in the Perf Clb page until above safe alt?
