Eights around pylons. • Failure to establish a constant,  level altitude prior to  entering the maneuver. • Failure to maintain adequate  altitude control during  the maneuver. • Failure to properly assess wind direction. • Failure to properly execute constant radius turns. • Failure to manipulate the flight controls in a smooth  and continuous manner. • Failure to establish the appropriate wind correction  angles. • Failure to apply coordinated aileron and rudder  pressure, resulting in slips or skids. • Failure to maintain orientation as the maneuver  progresses. Eights-on-Pylons  intuitive control of the airplane. Similar to eights around  pylons except altitude is varied to maintain a specific visual  reference to the pivot points. The goal of the eights-on-pylons is to have an imaginary line  that extends from the pilot’s eyes to the pylon. This line must  be imagined to always be parallel to the airplane’s lateral axis.  Along this line, the airplane appears to pivot as it turns around  the pylon. In other words, if a taut string extended from the  airplane to the pylon, the string would remain parallel to lateral  axis as the airplane turned around the pylon. At no time should  the string be at an angle to the lateral axis.  [Figure 6-10]  In  explaining the performance of eights-on-pylons, the term  “wingtip” is frequently considered as being synonymous  with the proper visual reference line or pivot point on the  airplane. This interpretation is not always correct. High-wing,  low-wing, sweptwing, and tapered wing airplanes, as well as  those with tandem or side-by-side seating, all present different  angles from the pilot’s eye to the wingtip.  [Figure 6-11]  The eights-on-pylons is the most advanced and difficult of  the ground reference maneuvers. Because of the techniques  involved, the eights-on-pylons are unmatched for developing  6-14
