Default G5

Thanks for the reply Bob but I am looking for something that will fit in a 3 1/8" instrument hole to replace the Gemini PFD. Don't get me wrong here, the Trutrak Gemini PFD is a fine instrument but I am striving for something I can shoot a flight director ILS in the 3 1/8" ADI and not something that will take up over half of my panel space.

I plan on getting one for a certified aircraft. According to the Garmin website it appears the optional antenna will cost $350. What's so special about this particular antenna and why can't I just use the 26c antenna? Beside the obvious answer that it's not a certified antenna.

Hello Jorge,

Thank you for your interest in the G5.

As specified in the G5 STC installation manual, the STC does not approve the installation of a GPS antenna. A separate airworthiness approval for antenna installation is required except for existing or previously approved installations.

Note also that the G5 may use GPS data from a GTN6XX/7XX or GNS4XXW/5XXW over the serial port if you have one of these IFR navigators installed.

It also specifies that other antennas that meet the specifications listed in the manual will work with the G5, but it is the installer?s responsibility to ensure that their choice of antenna meets FAA standards according to this specific installation.

The GA 26C antenna meets these specifications and works great with the G5, but receiving approval for using this antenna in the installation is likely to be challenging given there is no TSO sticker on the back.

It would be best to discuss antenna options with your Garmin dealer and installer, but you may also contact us directly via phone or email as shown below.

Thanks,
Steve

Default great educational resource

I downloaded the install manual that Steve posted, just to read for background info.
It is worth reading even if you are not yet ready to purchase.
Things like silicone fusion tape, yaw doublet, yaw body rate and more caught my eye, as being new to me.
The manual is well written, as usual. Garmin has put resources into the product that are commensurate with certified pricing.... but at experimental level investment. Well done !

Matt

If there is no pitot or static lines run to the unit will it then display GPS ground speed for airspeed and GPS altitude in place of baro altitude? I am looking to use this as a backup instrument and presently do have pitot and static at my panel. The only connection other than power I would have is an RS232 from a 430w. Are there any major drawback to this approach?

I will be mounting this on the instrument panel of an RV-6 and wondering if the internal GPS antenna would be ok in this configuration?

Thanks

I hope the G3Xpert will confirm if what I type is correct.


The G5 manual has the following:

Bottom of page 17:
NOTE: A G5 installed as a standalone unit may optionally be configured to disable its internal air data sensors. In this case, no connection to the aircraft's pitot/static system is required.

Page 37:
Attitude Sensors: (standalone installation only) Select "Disabled" to disable
the G5's internal air data sensors and hide airspeed, altitude, and vertical speed
information on the PFD. This option is intended for G5 installations where the pitot/ static inputs are not connected.


The above leads me to believe that the Air Data info can be turned off so as to not display.

Gary / Matt

So are you saying there will be a blank space for Airspeed and Altitude instead of showing GPS derived data?

Hello Tommy,

Yes, that is essentially correct, but we do show some additional GPS data. We should post an image of that since it looks pretty nice.

If you take this image (with airspeed/altitude sensors active), remove the airspeed and altitude tapes, make the GPS track bar full width, keep the two fields at the bottom, but replace baro setting with GPS altitude; you have a G5 operating with air data sensors disabled.



Thanks,
Steve

Default G5 GPS Data

I know the G5 can share GPS data from a G3X/G3X Touch LRU but where does that data come from, the CAN bus or the RS-232 data link?

Thanks
