Different MD-80 Tails

Mon May 24, 2004 10:49 am

Usually I know the answer to these kind of questions, but I need help on this one. Why do some MD-80s have "wedge" tails, and others have "cone" tails? Last time I was walking around DFW I saw both on AA's MD-80s.

Cone on the left, wedge on the right:

This could be just a slight difference or design change over the years to the same model aircraft. I think the newer ones are the 'wedge' tails to reduce drag.
Hey Obama, keep the change! I want my dollar back.

There was just a thread on this within the last week. Do a search for "screwdriver" tail and you'll find it and the many others on the subject.
