The given description of a servo tab is actually more accurately applied to a "balance tab" since the action merely serves to assist the pilot's input. With a true servo tab, the pilot's input is not delivered to the main control surface at all, but only to the tab. The aerodynamic force exerted by the tab is therefore the only means of operation of the main surface. It follows that there can be no such thing as an "anti-servo tab."

The example shown in the photograph is in fact an "anti-balance tab." It allows the pilot to control the main surface directly, but creates an opposing force that is directly related to control deflection, thus diminishing any tendency to over control.

Expert tag[edit]

The information on this page doesn't match some of the information I read in some aviation books. I think it requires expert attention and reliable sources. There are some good German sites on the subject such as this one but I am neither native English nor German speaker therefore I am not gonna try to edit the article.--Abuk SABUK (talk) 23:18, 1 March 2013 (UTC)

As a published author in the field I would probably qualify, so I have reviewed it and removed the Flettner claim. It can be put back in with a proper ref cited. Otherwise the rest of the text is either cited or is correct. - Ahunt (talk) 13:09, 2 March 2013 (UTC)
  • OK, thank you. While searching about this dilemma I stumbled accross this forum site. It looks like somebody who were also searching the subject himself came here and edited the article without enough info or relevant sources. In my language flettner is used for other secondary control surfaces such as trim, servo, balance etc. as well but that may well be a false friend.--Abuk SABUK (talk) 21:24, 3 March 2013 (UTC)
