The GAD 29 is an affordable ARINC 429 avionics data bus module that can be used to interface up to 2 IFR-capable GPS navigators with the G3X, G3X Touch and G5 series electronic flight displays. It can also be used to adapt the GTX 800 series active traffic system for use with G3X and G3X Touch displays.
This compact GPS/navigation data adapter, when installed with the GTN 750 or GTN 650 series or legacy GNS 530 or GNS 430 navigators, can enable such advanced features as GPS steering, WAAS LPV vertical approach guidance, HSI map navigation, coupled VNAV and more for access via your compatible flight display system.
The ARINC 429 interface is the most commonly used data bus for high-end general aviation and commercial aircraft. The GAD 29 module leverages this network interface to offer an affordable way for pilots flying experimental/LSA aircraft to expand the capabilities of their avionics — and access the latest and best in IFR capabilities from their GTN or GNS series GPS navigators.
Does what is required but be sure you get the right box. The less expensive one is experimental only. Does exactly the same thing as the more expensive, PMAâ€™d version.
No, it does not. Please see part # 11-11455 for the GAD 29 connector kit.
The Garmin G5 can directly connect to the GNS 420 thru the RS232 port, a GAD 29 is not required.
Yes, the GAD29B enables NAV features
If your aircraft is certified you will need the GAD 29B. This part is PMA'd certified where the GAD 29 is for experimental aircraft using a G3X system. Functionally they are the same.
Per the manufacturer, the GAD29 only has the GPS/Navigation interface. The GAD29B adds the autopilot interface.
Yes, per the installation manual Rev 9, a GAD 29 is required for installation for a G3X.
When interfacing a compatible autopilot to the G5, the Gad29B will be needed.
