MAP Missed Approach Point
MAHP Missed Approach Holding Point
ARC A DME arc terminator (The preceding flight plan leg is
described as an arc to this waypoint. An ARC
waypoint may follow another ARC waypoint.)
APPR An intermediate approach waypoint. These are
sometimes used as step-down fixes or to define a
course to the next approach waypoint.
An Apollo NMS TSO C129a approach will always begin at an IAF. It
will always contain at a minimum an IAF, FAF, MAP, and MAHP
sequence. The IAF and FAF may be combined. Waypoints may be
used more than once; the same waypoint could be the IAF, the MAP,
and the MAHP; however, TSO C129a non-precision approaches
require that there always be a distinct FAF to MAP leg. Intermediate
waypoints, of type APPR or ARC, may be anywhere in the sequence
except between the FAF and the MAP.
The following example uses the VOR DME RWY 12 GPS-overlay
approach to Baker City Oregon.
The Apollo NMS has a flight plan loaded from the Salem, Oregon
airport to the Deschutes VOR, DSD, to the Baker City airport, BKE.
An approach, the VOR DME RWY 12 approach with the D272Y
(waypoint on the BKE VOR 272 radial at 25 nm.) IAF is selected and
loaded. When viewing the flight plan legs, the following legs may be
viewed.
