If providing steering guidance through
the flight director, the FMS will command
the flight director to turn the shortest
distance to the missed approach holding
point. This direction of turn may conflict
When the MAP is the active waypoint, flight
plan sequencing will be inhibited on the TO side of
the MAP. On the FROM side of the MAP, AUTO
sequencing may be selected by the operator to go to
the next waypoint. To sequence to the missed
approach holding point or other waypoints following
the MAP in the flight plan, delete the discontinuity
after the MAP (otherwise, the FMS sequences into
the discontinuity) and select AUTO sequencing on
the Flight Plan page. The next waypoint will become
the active waypoint, with the inbound course into the
new active waypoint established by the geometry
between the MAP and the active waypoint. To
change the inbound course to the new active
waypoint, enter the desired CRS on the Flight Plan
page. If a holding pattern is enabled at the active
waypoint, the FMS will provide entry guidance into
the holding pattern.
discontinuity in the flight plan may occur when using
approaches. A discontinuity is associated with a
waypoint and requires crew action to resolve in
order to obtain proper flight plan sequencing. The
waypoint associated with the discontinuity can be
either the one preceding, following, or both. A
discontinuity is inserted int o the flight plan under two

n. Mission Flight Patterns.
(1) Mission Flight Pattern O verview. The
FMS800 allows definition of special MFP's to meet
specific operational requirements for military operations.
2. Figure Eight
4. Closed Random Pattern (CRP)
The FMS800 provides guidance within each
pattern type, including entry flight procedures similar to
those used for holding patterns.
Any MFP may be associated with up to 20 fixed
waypoints in the flight plan. When the aircraft crosses a
pattern fix, the pattern guidance is activated, suspending
normal leg advance until the MFP is exited.
(2) MFP Definition. Each pattern provides a
definition on the MFP page. To create a new MFP,
access the MFP pages from the Patterns page. Refer to
Figure 3C98 and Table 3C-69. There are four
parameters that define the racetrack and figure eight
