HSI Suggestion

[hankster]

On an ILS approach, one of the ways to improve your tracking performance is to use the ground track info from a GPS receiver. For example, the ILS into my home airport has 176 as the final approach course. While intercepting final, I turn to a heading that puts the ground track at 176, and note that heading as a reference. Then, I make a heading adjustment to center the cdi, and when centered I return to my reference heading. The ground track makes "donut" approaches easy.

I don't have a dynon product (yet), but I would like to see a magenta ground track triangle on the localizer page of the HSI. It would make those approaches soooo nice. Of course, I might get fat from all the donuts .

Thanks.

We've had GPS ground track on our HSI page since we released it last October.

You can see it on this screen shot, just to the left of the current heading

The next update this month puts GPS track and course setting right on the heading tape of the EFIS page.

Thanks for the quick reply.

Yes, it does show the ground track when the HSI is on it's GPS page. However, to do a legal ILS, you have to track the localizer/GS, not the GPS. Does the ground track triangle appear when the display is showing Localizer/GS? I don't see that in the documentation.

Thanks again.

If it has GPS data, yes, it shows this on the HSI all the time, even in ILS mode.

The issue is that on a D100/D10A we can only read one serial source at a time. To show ILS and GPS track at the same time, you'll need an EFIS and EMS in the plane or a D180.
