NK ClearNav Manual • Version 0.5 • July 3, 2008 optimizing your glide angle. However, many more experienced glider pilots consider it to be less safe than leaving the MacCready number at a setting that matches the actual soaring lift conditions. The reason is that at a MacCready setting of zero you are at the ragged edge of making it home. You have no margin for error (or sink). You can’t slow down any additional amount to stretch your glide or speed up to get through sink.
