Operating Modes
The NavTalk Pilot automatically selects between
airborne and ground modes based on docking (cradle)
status. Under certain conditions, the cellular transceiver
is disabled to prevent interference to both the airborne
cellular and conventional cellular networks. The table
below indicates the unit operating mode as it applies to
ground speed and cradle docking.
