G3X questions

[Lyndon]

The G3X Garmin. It requires some other ancillaries for it to operate. What actually else do I need to buy with it. Pitot Tube, AOT probe,  I believe it has an inbuilt GPS. So do I need a remote GPS or areiel for it to operate correctly. Does it need a magnetometer??? Does it need anything else.  I want to save on bundled shipping.

Thanks Lyndon

When you get a magnetic compass make sure it's for Southern Hemisphere.   Nev

Basics for meaningful display on Garmin G3X Touch;

GSU25 ADAHRS

GAP26 Pitot/AOA

GAD13/GTP59 interface/temp probe

GMU11 Magnetometer

GEA24 interface for engine sensors

 

You can do cross country (but not IFR) naviation using the internal GPS.

You need an antenna either GA35 (external fuselage mount) or GA26 (internal dash mount)

Maps are additional cost.

 

Backup;

G5

G5 backup battery

GA26 GPS antenna (2nd)

 

You also need a radio that will accept audio alerts from the G3X so probably a Garmin radio.

 

An ADS-B in/out transponder is also recommended.

Note you need an approved GPS source for ADS-B which the internal G3X GPS is not.

 

Real answer is talk to a Garmin shop, above is just the basics.

 

 

PS Buy the 10 inch screen as the 7 inch displays a lot less (not just smaller screen).

The magnotomer, what exactly does it do and is necessary for VFR.

Thanks Lyndon

Google is your friend;

Consider it a remote compass that feeds into the G3X Touch (and G5).

I've got all those items you listed  sorted except the Magnotomer and engine interface ( not required for the Rotax). 

I take it the G5 back up shares the same Pitot tube ?

Thanks , the GPS is not accurate enough for VFR ???

The G5 will have an antenna for its GPS.

I'm guessing the G3X will have the same set up. Thus two independent GPS units, or would they share the same remote antenna??

Yes, the G5 shares the same Pitot and temp probe.

 

I would be checking with the source of your info as a Magnetometer is a essential part of your setup.

Also, are you sure a GEA25 is not required ? The 915 I have seen use it and I believed the 916 also required it.

You need a magnetic compass

 

You need a separate GPS antenna for the G5

Fantastic, thanks so much.

 

One last question, I've opted for a remote radio. I will use it thru the G3x. Im thinking it's modern and will be fine. I also like the idea of working on one panel. I have also opted for the AP 507 head unit. ( Which is contrary to the above). My thinking is I like to feel knobs and buttons and wheels when making inputs to the way the aircraft flys. 

Right choice on the Radio?

Thanks Lyndon

If you have the panel space I would personally go with a panel mount radio. Some people like knobs and it improves the resale.

Cost is similar.

Either a remote mount or panel mount Garmin radio can both be controlled from the G3X Touch.

True. I never thought of that. I can use it remotely. Plenty of room on the panel. 

I will probably change that now.

Check which units come with mounting/connector kits.

Some do and some do not.

 

Can delay your installation when you discover something missing.

GEA25

I think your correct. I've misunderstood. I will have to order one of the above as well.

I would run your config past a Garmin dealer or Garmin Aus support line first.

Bert Flood Rotax may also be able to confirm what you need to interface the 916 engine sensors to a Garmin G3X Touch.

Some retailers are a bit hit and miss with what you need.

You do not want to pay too much (or too little) and cause delays to your installation.

Will do
