Another item that you should notice
in the flight plan is the line that has
*NO WPT SEQ on it (figure 6-16).
This is what is referred to as a fence
and the purpose of this line is to tell
you that the KLN 94 will not automat-
ically sequence past the waypoint
that precedes the fence. The waypoint before the fence is always the
missed approach point. The reason that waypoint sequencing is not
allowed is that many missed approach procedures require specific actions
before going to the missed approach holding point (e.g., climbing on a
fixed heading until reaching an altitude).

You may notice waypoints with somewhat strange names. For example
LAX18 has a name that is not normal for a waypoint. This is an example
of what are called “terminal” waypoints. These are waypoints that are
associated with a specific airport. They are used to define a spot on the
ground that does not have a normal waypoint name. In the case of
“LAX18” this point is 18 NM from the LAX VOR on the 68° radial. Another
waypoint, MA25B, is also a type of terminal waypoint. In this case this
point is the missed approach point for runway 25. This approach applies
to both the left and right runways so the letter B is used to mean “both”.

There are a few other types of terminal waypoints that will help you to fully
understand GPS non-precision approaches. The naming convention for
these waypoints are as follows:

Fxyyy

• F stands for Final Approach Fix

Ixyyy

• I stands for Intermediate Fix

Cxyyy

• C stands for Course Fix

Mxyyy

• M stands for Missed Approach Point

RWzzz

• RW stands for Runway Fix. This is usually the MAP for
the approach

• zzz will be a runway number possibly including L for
Left, R for Right, C for Center, or B for Both.

Daaab

• D stands for DME arc waypoint. Some DME arc way
points use the following convention for waypoint names
while other DME arc waypoints use normal five letter
identifiers.

• aaa is the radial that the fix is on from the reference
VOR
