Boeing 737 Flap design classic v's NG

[nomorecatering]

It seems there has been a rethink on flap design in recent years. Taking the 737 as an example, they went from 3 section units with it seems much more rearward travel at small flap settings before deflecting down. The NG flaps seem to have far less fowler action at take of flap settings and much more downward travel. As well as 2 section design.

Is there any benefit, the NG would seem to add more drag than the classic at take-off settings. There must be a weight/complexity saving. Is there iny difference in the CL between the two?

[Capt. Inop]

Is there any benefit Less complex systems double slotted vs triple slotted flaps.

Better stability at flaps 40 (personal experience) and less noice on higher flap settings.

Except from that we're allowed to take off with flaps one (slats only) on the NG.
