A320 ARS vs Manual Flap Retraction
It is recommended to use Airbus Auto Retraction System (ARS) on A320/321 for a heavy weight takeoff with speed constraints like 220 knots in SID. My question is suppose I am going to takeoff in 1+F config. Now just by looking at characteristic speeds like F, S & O and climb constrain speeds is it possible to decide if one manually retracts flaps at S speed or let ARS retract flaps and then manually retract slat after climb constrain point is crossed. In short, is there a way to decide ARS vs Manual Retraction based on numbers?
