Table 3C-30. Attribute Designators
A course reversal is enabled at this waypoint.
A DME Arc will be flown to this waypoint. DME Arcs only exist in published GPS
The waypoint is designated as the Final Approach Fix (FAF) for database and tactical
A holding pattern has been attached to this waypoint. If the waypoint is an IAF or
missed approach holding point with a data base holding pattern attached, this attribute
is displayed on the holding Flight Plan page when the holding pattern is enabled.
The waypoint is a valid intercept solution for a moving target.
The waypoint is designated as the Missed Approach Point (MAP).
This waypoint is a fix for a pattern that will be executed upon arrival at the point.
This waypoint is part of a STAR.
This waypoint is part of a SID.
The waypoint has a desired time of arrival associated with it. This indicates that a Time
Navigation (TNAV) function will be performed to obtain the Required Time of Arrival
(RTA) on the Flight Plan Waypoint page.
The waypoint has an altitude specified that will cause vertical navigation to be
Table 3C-31. Attribute Hierarchy
The right-most column of attributes
shown in this table is deleted first when
used in combination with other listed
waypoints beyond the active waypoint are in the
flight plan and the flight plan advance mode is
automatic (AUTO or FLYOVER mode), the FMS-800
waypoints. It also automatically transitions smoothly
from one waypoint to the next.
To sequence past a waypoint, the aircraft track
angle must be within 90° of the active leg course
and the Track Angle Error (TKE) must be within 90°.
Otherwise, sequencing will be inhibited and guidance will
continue to reference the inbound course to the
To prevent overshoot of the next leg, automatic leg
switching in AUTO mode includes turn anticipation, up to
30 nm prior to the waypoint, for course changes 150°.
Over 150°, the waypoint will be overflown and a teardrop
turn is made to intercept the next leg. Refer to Figure
When the change in the resulting course
between flight plan legs is greater than 150°,
the FMS will provide guidance to turn and
intercept the next course, resulting in an S-
turn maneuver into the course. The course
to the next waypoint is based on geometry
between waypoints, not waypoint course
guidance, for smooth turns.
When the pilot has selected the FLYOVER mode,
leg switching is also automatic, but each waypoint is
overflown prior to turning to intercept the next leg.
Prior to the leg switch point, the waypoint alert light
illuminates and the waypoint number on the Flight Plan
page and the ¯ to ¯ indicator on the Lateral Steer page
will flash for 10 seconds.
