ear of main wingtip being bent down bodily to increase the lift. This isknown as wing warping, and is practically a singleacting process since the depressing force on the high tip AEROPLANE PRINXIPLES 33 is seldom as effective as the lift on the low. Warping isnot generally used on modern biplanes… … FlG-gg Fis^ga Figs. 17-23. Showing Use of Ailerons in Maintaining Lateral Balance. Banking and Turning. In making a sharp turn theouter wing tip must be elevated to prevent slipping side-wise through the effects of the centrifugal force (sideslip). This is known as banking. The faster andsharper…
