Winglets On Horizontal Stabilizer?

Tue Aug 02, 2005 10:25 am

I was reading the post about winglets and the different types and how effective they are. So why not have winglets at the ends of the horizontal stabilizers?

Because they are not needed. The vortices that form on the wings are not as big a factor on the horizontal stabilizer and there is no added benefit to adding them.

Sure they can have it. On the Beech 1900D as an example:

Quoting Skydrol (Reply 2):

Those aren't winglets as such. They are there to augment the vertical stabiliser (which is the same as a King Air stab. and is too small for the a/c) and to enhance the aircraft's stability in a one-engine-out situation (they are in line with the engines). A winglet's function is to reduce drag associated with tip vortices.
