If you look at the CL alpha curves you will note that the
gradient for the swept wing is less than that of the straight wing. An
important point that comes up time and time again in the exam is that a swept
wing of the same area produces less lift than a straight wing.
Now on entering turbulence, a gust will change the angle of attack,
the change in CL for the swept wing will be less than for the straight wing.
Swept wings are less sensitive to gusts.
