ATR-72-212 Airfoil shape

Since I am doing my upgrade training and ATP in the ATR-72 I am looking for more information than the ATR-72 FCOM has. Does anyone else have links to things I can learn about the super-critical wing design it uses?

This will be the first one to get, if it makes it through it's C-check.

Eh, who cares. Pull back on the stick, houses get smaller, push the stick down, houses get bigger...

I do because I am as bored as bored can be. I have two more weeks before sim with nothing to do besides sit at the beach.

NACA 43018 from what I found on google.

Interesting that doesn't look like a super-critical airfoil like they say.

I'm no Expert, but I think it would be pretty weird if they put a supercritical airfoil on a plane that's MMO is .55

Haha I know but some of the manuals said it was a supercritical airfoil. The Dash has one and was slower than the ATR

This was kind of interesting and doesn't address characteristics in the lower mach numbers and they use a swept wing turbojet as the model. Couldn't find anything on a high aspect ratio, straight wing supercritical airfoil....

This is a good one as well and also addressed another question I had with the concave vs flat trailing edges.
