D
Before flying the approach, the waypoints, as well as constraints in
the procedure must be verified with the approach charts. When the
database contains more waypoints for the procedure than the chart
actually shows, the flight plan must reflect the selected procedure.
The database does not contain step down fixes on the final
approach when the constraint at the step down fix is satisfied by the
vertical descent path into the MAP.
D
After selection of an approach, the following must not be done to the
approach procedure.
— Add waypoints into the middle of an approach procedure.
— Relocate procedure waypoints in the flight plan.
— Remove waypoints from an approach procedure (other than by
deleting the FROM waypoint, conducting a direct--to, activating
another approach, or activating another flight plan), and then
continue to fly the procedure.
— Changing an altitude or angle constraint associated with an
approach waypoint.
— Add holding patterns, orbits, or radial intercepts to approach
waypoints.
— Changing the destination and then continue to fly the approach
procedure to the original destination.
The examples, listed in Table 6--1, illustrate approach transitions and
how the FMS flies the transitions.
Missed Approach
The FMS shows a MISSED APRCH prompt at 6L on the active flight
plan pages. This occurs 2 NM before the FAF or 5 NM from the runway,
whichever is reached first. When the prompt is selected, the missed
approach procedure is activated and inserted into the flight plan
following the MAP. The go--around button(s) must be selected to
activate the go--around mode.
The aircraft go--around button(s) are also used to activate the missed
approach procedure, but only while the MISSED APRCH prompt is
displayed.
When MISSED APRCH is selected, the APRCH annunciator goes out
and the FMS transfers from the approach mode to the terminal mode.
