Orbit Pattern
The SAR exit waypoint is a duplicate of
the previous waypoint. This SAR
pattern is unique in that the navigation
path never goes through the waypoint.
The path is a circle around the waypoint
intercepted along tangents. With no
other menus displayed on the PFD,
CONT (L2)
appears to allow for
continuing out of the orbit and normal
sequencing in the active flight plan.
