Basic Operation
Nav Radio (VOR)
Press
VOR
to activate control of the internal Nav Radio. All other functions will continue to function normally,
such as navigation on active flight plans.
DME Distance
Distances, such as to a Localizer/DME waypoint (equivalent to Localizer DME), are based on calculated
distances from GPS information. The GNS 480 will choose the DME that is the closest to your geographical
location within 200 nm. If a station identifier has been decoded by the NAV radio, the closest DME from the
list with matching frequency and station identifier is used to determine distance. If no station identifier has
been decoded and there are multiple DME’s with the same frequency found within the list, no GPS distance
will be displayed. If only one DME is found that matches frequency and the DME is not part of an ILS, it will
be selected to determine the GPS distance. This means, if a DME is found that is part of an ILS, a decoded
identifier match is required. If the decoded identifier is not in the list no distance will be provided. No distance
will be shown for a localizer that does not have a collocated DME.
ID
Press the
ID
key to toggle the Nav audio between Voice or ID. After pressing the
ID
key and the ID function
label is highlighted, the Morse ID will be available. When the ID function label is not highlighted, Nav audio
Voice is selected.
Monitor (MON)
Press the
MON
key to toggle the Nav channel monitoring function. When monitor mode is active, a MON an-
nunciator will appear on the left side of the standby frequency, the standby radial replaces the active identifier,
and the MON function label will be highlighted.
Frequency monitoring allows you to listen to the Standby VOR frequency while the GNS 480 monitors the Ac-
tive frequency for activity. Radial information for the monitored VOR frequency will also be displayed. When
Active frequency receives a signal, you will hear the Active frequency until its activity stops. Pressing
MON
will
be ignored for ILS frequencies. If Voice or ID functions are active, the Nav radio will temporarily turn off the
ID function until the Monitor function is turned off.
