Conditions:
-max speed on SID 220
-S speed at 208
-Green Dot at 223 kts
1. with S being the min slat retraction speed why am I not allowed to select Flaps 0 after passing S speed + a positive trend vector? Why do I have to wait after the speed restriction has been passed in order to reach green dot? Is S speed just defining the speed where you can retract to 0 and with having positive acceleration it will fit perfectly to reach green dot speed when finished
2. how would you manage this situation?
I was thinking about pre-selecting/pulling Speed to 205kn avoiding auto flap retraction..then after passing the speed restriction order „manage speed“ and retract the flaps to 0?
thank you indeed!
Put in MCDU preselect speed 220kts and after takeoff let flap auto retract then retract slat and the aircraft will automatically fly 220ks in select speed. Not much issue.
