IfalowerCDIscalesettingisselected(i.e.,1.0or
0.3 NM), the higher scale settings are not selected
during ANY phase of flight. For example, if 1.0 NM
is selected, the 500W-series unit uses this for en
route and terminal phases and ramps down further
during an approach. Note that the Horizontal
