The NAV 122 is being brought back as the NAV122D/GPS
due to popular demand. In fact, at the time it was discontinued the NAV122 was one of the most desired
NAV systems of the day and today is one of the hottest items in the pre-owned avionics market. NAV
122's were discontinued only because the technology of the day drove production cost
up to the point at which the price became non-attractive.
The NAV122D/GPS is a self-contained 200 Channel NAV
Receiver, 40 Channel Glideslope Receiver, VOR, Localizer and Glideslope Indicator
all packaged to fit into a 3.0" instrument hole. The NAV122D/GPS, is completely
re-designed utilizing "Surface Mount Design Technology". It includes a resolver and
interface connections which enable the additional capability of being used as the
required "Left / Right" Indicator, as required in IFR approved GPS installations.
It will "Directly Replace . . . Pin for Pin (hole for hole) the original NAV 122 Series
clear back through the early NAV 12.
(NOTE: NAV 12 replacement will require connector changes by the installer and there are no internal marker lights or receiver.)
