Angel Angle of Sweep B737 NG Wing

G'Day ppruner's,

Was covering some lessons in the 737-400 CBT and it mentioned that the wing sweep was 25 degrees.

I have been through the NG CBT and it doesnt mention the sweep angle. I was asked the question at an interview and have not been able to find the answer.

I understand that boeing calls the it a super critical wing, it has a greater span etc but cannot find any reference about the new sweep angle.

Can anyone help me?

Thankyou in advance for your replies.

Wing sweep angle is one thing the 737 Classic and the 737 NG have in common.

Both are 25 deg. This is a popular sweep for this class of airplane as the A320 wing is also 25 deg.

The value of the advanced technology airfoil on the 737 NG is apparent.

The Classic LRC is around .74M while the NG LRC is around .80M.
