System Overview 1-3
IFD410
The Avidyne IFD410 differs from the IFD440 in that there is no
internal VHF communication and navigation transceiver. Its
primary function is to conduct GPS navigation, provided it is
connected to an external navigation source selection annunciator
and CDI/HSI indicator that are installed in the required field of
view. The IFD410 cannot be used to execute terminal area
procedures that rely on VHF navigation. The IFD410 bezel differs
physically from the IFD440 in that the radio controls along the left
side of the bezel are absent, the navigation source selection knob
is replaced by an OBS button, and the volume knob is replaced
by a single-function power on/off button.
