When to select flaps up in a A320?
I have noticed that sometimes, when heavy and hot, if I order flaps up just when passing S speed, the airplane will stop climbing, or even slightly sink for a while (more if in a turn).
But when I delay asking for flaps up because of this, letting speed to get closer to Green Dot, the captain will "force" me to ask for it putting his hand in the lever, or announcing "s speed" or even selecting it on his own. Even if VFE is still not a problem.
żIs there a manual or briefing or whatever that makes any recomendation on this subject?
thanks
