Marauder Posted January 17, 2014 Author Report Posted January 17, 2014 No, no GDL-88. Thanks! I just realized you are a 1975 F owner and you did the one piece window out back. I gotta do that mod... Can you post more pictures of your plane in your gallery? I noticed a few differences from mine already, wonder what else changed. Curious to see what you have done to the interior. Quote
romair Posted January 26, 2014 Report Posted January 26, 2014 speaking of GTN series, I have the GTN 750, and one of the options to show on the main screen is wind direction and speed. However, with that selected, nothing ever comes up. Any ideas why? If you go in one of the submenus (I think utilities), you can manually input the altitude, bearing, etc, and it will calculate it for you. To me that just seems like an electronic E6B...i think it should be able to calculate all this automatically. There is an option of "use sensor" but that does not seem to make any difference. Any thoughts/experience with this? Stefan Quote

Any thoughts/experience with this? Stefan This is a legitimate gripe that I share with you. What isn't mentioned anywhere is that this field is dependent upon an Air Data Computer being installed and interfaced to the GTN. I believe the 530W displays this as standard equipment, which is another feature that was not carried over to the GTN. The other is a numeric display of which radial you are on when tuned to a VOR.

romair Posted January 26, 2014 Report Posted January 26, 2014 so is there a way to get this information into the GTN, and what kind of expensive equipment will it require? Quote
flyboy0681 Posted January 26, 2014 Report Posted January 26, 2014 so is there a way to get this information into the GTN, and what kind of expensive equipment will it require? You would need one of the following approved air data computers. None of these solutions are cheap. King KDC 281 King KDC 481 Insight 1000 B&D 90004-003 Quote
Bob_Belville Posted January 26, 2014 Report Posted January 26, 2014 I see wind on the Aspen MFD (which uses 750 GPS data.) Quote
Marauder Posted January 26, 2014 Author Report Posted January 26, 2014 I see wind on the Aspen MFD (which uses 750 GPS data.) Same for my 650. Takes the GPS data and does the calculation for you. Quote
romair Posted January 26, 2014 Report Posted January 26, 2014 Well, that would be an expensive upgrade... Quote

ArtVandelay Posted March 25, 2017 Report Posted March 25, 2017 You definitely will need some way of getting IAS and OAT data to the GTN before it can calculate the wind speed. Quote
jlunseth Posted March 28, 2017 Report Posted March 28, 2017 I have a KT74 which provides TIS-B (plus traffic via a Stratus2 to my iPad) to my 430AW. I get traffic alerts. I have never thought much about how I get them, they are kind of a pain since TIS-B is only a portion of what I get on the iPad. Quote
75_M20F Posted March 28, 2017 Report Posted March 28, 2017 (edited) My GTN750 has announced traffic a couple times here and there (and the screen auto zooms in on the traffic threat... last time it was SWA over top of RDU.......) Other then that it has remained silent. I try to avoid close encounters with terrain so I wouldn't know if it will announce terrain or not. I have it in the shop now for the OS update.

I have never thought much about how I get them, they are kind of a pain since TIS-B is only a portion of what I get on the iPad. It's TIS-A from the KT74, to get TIS-B you need a 978 capable box. 1 Quote
jlunseth Posted March 29, 2017 Report Posted March 29, 2017 Your probably right. What I know about it, is that it is incomplete and annoying, so I am looking for the way to just turn it off. I get much better traffic on the iPad (ADSB) when I want it. But the point I was makiing is that I am somehow getting aural traffic alerts through just the 430 and the KT74. Not sure how that is happening. Quote
flyboy0681 Posted March 29, 2017 Report Posted March 29, 2017 To get the full traffic "experience" you'd need the GDL-88. Whenever I fly it never ceases to amaze me not only how much traffic is around me, but the accuracy of where it is. I fly around a fairly congested area and the GTN does sound off quite often. 1 Quote

Not sure how that is happening. You are probably flying near one of the TIS-A coverage areas. These areas were created around congested airports as part of the initial mode S push in the 1990s. It is being discontinued.https://www.aopa.org/advocacy/advocacy-briefs/air-traffic-services-brief-traffic-information-servicesSent from my iPad using Tapatalk Pro Quote
jlunseth Posted March 29, 2017 Report Posted March 29, 2017 Yes it mostly happens around metropolitan areas, just when I would prefer to see the nav screen on my 430, and to focus on such things as putting the gear down, a little screen pops up that I have to clear and "she" has to say something. It is a pain. But again, my point is that the aural alert appears to be generated by the 430. Quote

It is a pain. But again, my point is that the aural alert appears to be generated by the 430. I believe it is generated by the 430 and the trigger is the mode S from the transponder. From the Garmin 430 site:"Add the GTX 330 Mode S transponder, and GNS 430W will also display Traffic Information Services (TIS) alerts that identify surrounding air traffic."What I don't know is if and how you can turn it off. This was one of the concerns I had when I started looking at the ATAS voice capability from L-3. I'm from the school that nuisance warnings tend to get ignored. From what I have read from L-3, they have built a logic into the voice alerts to only alert when a conflict truly exists. I think this is the basis of the "TargetTrend" technology that is built into the GTN series. TIS-A probably doesn't take advantage of this. Sent from my iPad using Tapatalk Pro 1 Quote

We have the GDL 88's in a few club planes and I have the GTX345R in the Mooney w my 750. I think these two provide the same data. Has anyone noted any differences? Quote
flyer7324 Posted March 29, 2017 Report Posted March 29, 2017 I get aural traffic alerts in addition to the visual traffic alert. Marauder I have another question for you. I have the Aspen pro 1000 and 650 but unlike you in ur videos I cannot any course reversal depiction on my Aspen. I sent the video of u to Aspen and they said there's a problem at Garmin's end with the way they changed how they "label" the data that the Aspen can't read. They haven't been able to reconcile how u get though. Any thoughts on that ?Sent from my iPhone using Tapatalk Quote
