Selecting COM and VLOC Frequencies
While the GNS 530 is acquiring a position, take a
minute to dial in the active and standby frequencies to
be used for the first phase of the flight. The GNS 530’s
display is divided into separate windows (or screen areas),
including a COM Window, VLOC Window, and the GPS
Window (Figure 1-12).
