The following examples of typical approaches
illustrate where the LOC-DME waypoint may be
useful. In addition, examples using DME information
from VOR waypoints are given.
ILS with DME Data from ILS DME Antenna
The following example uses the ILS Rwy 10L
approach to Portland International airport. This
procedure describes the use of your Apollo GPS
distance display to supplement the DME distance as
you reach the BUXOM intersection.
1. Prior to intercepting the localizer, or before
reaching the BUXOM intersection, set up your
Apollo GPS with IVDG LOC-DME as a waypoint.
2. Press
DIRECT-TO. Select the IVDG LOC-DME
waypoint using the
LARGE and SMALL knobs, and
then press
ENTER.
