Best glide speed is a determined by the interection of the parasitic drag
curve and the induced drag curve. Parasitic drag is not going to be affected
by weight but induced drag is somewhat affected by weight as well as the
location of the CG. So, yes, it *could* reduce or increase slightly depending
on the CG.

Does Best Glide Speed reduce with weight the same as other airspeeds?
