Thread: Garmin G5 and AF5600T

    Garmin G5 and AF5600T

    Hello,
    I know that I can connect the G5 to the AF5600 for AHRS info. That is really nice. However I would like to know if the G5 can get the position, oat and navigation information via the same connection.

    Thanks,
    Filipe

    This is not possible. No G5 RS-232 inputs can be assigned when the G5 RS-232 output is set to the text format at 115200 baud that allows for us to use it as an ADAHRS.

    Does this imply that you can’t use an rs-232 input from a gps navigator and you have to use the internal gps of the g5?

    The g5 has a coaxial connector for an optional external GPS if the internal GPS has unsuitable reception. Important to note that the G5 only uses GPS for 1) sanity checking the gyros 2) ground speed 3) displaying GPS track if a magnetometer is not installed. The baud rate mismatch is what makes it impossible to assign an RS-232 input when the output is 115200 baud; Garmin Aviation and the most common NMEA format are 9600 baud only.

    Use of the G5 as a backup navigation instrument to an AF-5000 installation is a whole other ball of wax. While it cannot be fully supported when the G5 serial port is tied up for use as the backup ADAHRS data source, and with the navigator ARINC and RS-232 connections already wired to an AF-5000 series system, one thing is true: The G5 receives ARINC data from a GAD29 ARINC adapter on the same formats at the same speeds as an AF-5000 receives ARINC data from a GTN or GNS/IFD navigator.

    As such, while we haven't tested this and don't warrant that it will work, it should be possible to install a GAD29 ARINC adapter and GMU 11 magnetometer on the G5's open CAN connection, tee the wiring on the nav and GPS ARINC (out only) to both the GAD29 and AF-ARINC / SV-ARINC adapters, and have the G5 work as a backup CDI display. Because the G5 is not sending ARINC data back to the navigator, you will be unable to adjust the OBS from the G5, nor will it be sending the navigator the airdata necessary to couple missed approaches. Of course, if your AF-5000 goes down, you've lost your SV-Autopilot or GPSS mode on your Trutrak anyway, and so will most definitely be hand flying a missed regardless.

    There may be other limitations to such an installation that haven't been imagined. So suffice to say, if anyone does actually try this, please post back and let us all know how it works for you.

    Thanks for the explanation!
