The  FMS  supports  two  types  of  holding  pattern definitions as follows: 1.   User-defined holding patterns attached to fix waypoints by the user. 2.   Published   holding   patterns   that   are derived     from     published     instrument approach charts. A  holding  pattern  may  be  associated  with  one fixed   waypoint   (the   holding   fix).      When   the   aircraft crosses  the  holding  fix,  holding  guidance  is  activated, suspending    normal    leg    advance    until    the    holding pattern   is   canceled.      Three   parameters   define   the holding   pattern:   inbound   course,  turn  direction,  and pattern length. (2)   Holding   Pattern   Entry   Guidance.      An advisory and steering guidance for the entry method is computer in accordance with standard FAA procedures.    The  geometry  for  a  standard  (clockwise) holding  pattern  is  shown  in  Figure  3B -65.    For  left- hand  turns,  a  mirror  image  of  each  entry  procedure applies.  This advisory is displayed on the Hold page.   Refer to Figure 3B-65 and Table 3B -49. Prior  to  entering  the  holding  pattern,  the  entry advisory  will  show  the  expected  entry  based  on  the inbound  course  to  the  holding  fix.    When  the  aircraft passes  the  holding  fix,  the  advisory  will  be  updated  to show   the   actual   entry   in   progress   based   upon   the aircraft track at the holding fix.  Refer to Figures 3B -66, 3B-67, 3B-68,  and  3B -69  for possible entries into the holding pattern.
