GNS480

Jim,

I understand from reading those posts that there would be an update, but what the scope of that update is, I didn't really understand. Much of their discussion is over my head.

Good Day

I got the GNS-480 installed and very impressed with it.

I have a question in regards to fuel flow data, we were able to allow the 480 to talk to the JPI 700 and provided the necessary data to give me fuel required, remaining etc on the JPI but I do not get any data on the 480.

Does any one know if I can feed data from the same flow meter into the 480 as we do the JPI?

Thanks

Probably not. My Insight G4 gets time to destination from which it calculates fuel remaining data, but fuel flow data is not supplied to the 480.

Dear Bill,

The JPI and the 480 will talk to each other just fine. At least mine do. You probably don't have all the wires hooked up properly. I think there is an Rx, Tx, and ground wire that all have to be hooked up on that particular port. You will have to check out both of the installation manuals to get the specifics. There are also some set up adjustments (configuration) in the JPI that have to be set properly. On my 2nd map page on the 480 (there are four pages) I have all the fuel information displayed. It only takes one click of the round knob to get there on my 480. Each of the pages has user selectable data that can be displayed.

As we have all discussed previously on this thread, the 480 is a very capable unit, but the learning curve for the pilot is steep. It's also possible that the fuel flow information is already being sent to the 480 and you just aren't pushing the right buttons to bring it up. I can't tell from here which is the culprit. My recommendation would be to first find an instructor who can lead you through some of the 480 basics and at the same time use his wisdom in your particular plane to see if fuel flow really isn't being received by the 480. If that is the case, then the second step would be to a go to the person or shop that did the install and have them double check that wiring or the configuration until they can show you that the info is on the 480 as well as on the JPI.

I highly recommend that you seek out a 480 instructor that is very familiar and can check that for you. My strong hunch is that is where you will find the problem, but can't be certain from this distance. Reading the owners manual in depth would be helpful for you also.

Sincerely,
Skip Dykema

@Bill (Robert Miller) ... the transducers in my twinco talk to the Shadin, the JPI and fuel information is also displayed on the 480. I think that it is a JPI /480 interface... that makes the 480 fuel smart.

All the best!

Thanks everyone for the all the information on the 480, with our long winter up here in the great white north (still 2 feet of snow at my airport north of Calgary) I was finally able to go out and work on my fuel display issue in the 480. Found out the JPI was putting out data to the 480 Ok and in the configuration set-up in the 480 you have an option to select fuel data input or FADEC input and my avionics fellow had set fuel and we needed to set FADEC. Simple change but took a while to trouble shoot as you cannot run configuration on the 480 when the aircraft is operating.

Skip is correct it is a steep learning curve to learn how to operate the 480 but it is sure worth it so far.

Bill,

If you go to the Garmin website and search for the 480 you will find there is a PC based simulator for it. I've used all the Garmin simulators for different aircraft I fly and while the 480 sim is not as well developed as say the 430/530 sim in that it does not have the HSI and altitude selector it is a very good sim and runs the actual 480 code. it's a great way to learn in the comfort of an armchair vs in the air.

If you go to the group on Yahoo... and read a bit of history... there is a library link for the very latest simulator... I seem to recall that it is more recent than the one on Garmin (but I may be wrong). It was sent to a fellow that has written a couple of "How To" books about the 480 and while he held it for a bit... he eventually put it in the library because at that time Garmin had not.

Very good to know - thanks Jim!

Thanks Jim and Charles for the information on the 480 simulators I will take a look on the sites and see what I can find.
