Approach Procedures
There are several other types of waypoints which may appear in your
Apollo NMS loaded approach and which may or may not appear on
your approach procedure charts.
Following is a brief description of these types of waypoints and the
naming convention followed.
Identification
Each waypoint in an Apollo NMS flight plan has an identifying type
and a name. When you view the flight plan legs, by turning the Small
knob while viewing a flight plan in FLIGHT PLAN mode, the display
will show a "FROM" waypoint and a "TO" waypoint for each leg.
Under the names for the waypoint, the waypoint type is usually
displayed although this field may be changed by pressing sel and
turning the small knob to show other information such as leg ETE. The
from-to-next page, located one click to the left of the 'home'
navigation page, always shows the waypoint names and types for this
two-leg "window" view of your active flight plan.
Most of the waypoint types for en route waypoints are quite familiar.
They include ARPT for Airport, VOR, NDB, INT for intersection and
USER for a user defined waypoint.
The approach waypoint types will usually also have familiar types, but
there may be a few types which are new. The approach waypoint types
include:
IAF
Initial Approach Fix
FAF
Final Approach Fix. (Note that there must always be a
Final Approach Fix inbound for TSO C129a
approaches. When an underlying approach, such as a
VOR or NDB approach does not have an inbound
FAF, one is created or added.)
IFAF
Combined Initial and Final Approach Fix with no
intermediate waypoints. (Sometimes a procedure turn
or course reversal is required - this usually depends on
the direction of flight)
